Green Architecture

Green Architecture-a misunderstood word

Green Architecture is probably misunderstood and misrepresented ie the Green certification program make a building Green.Neither is it that  merely planting of green plants in building does not represent Green Architecture. Existing Green Certification programs exists but the focus is skirting the topic and issues at large.

But rather ,the planting of Green plants must have a purpose, which ought to be, to provide benefits of eco biodiversity, reap the benefits of health as  type of home affects your health and improves the Biodiversity of the surrounding environment.
And it ought to saves the eco system and our future depends on it. Our future and sustainability depends on it on how we teat the Climate system, which we all share..Global temperatures are rising and it is said that the most conservative calculation indicates a temperature increase by 2-6 degrees C by the year 2100. The climate systems are being aquandered.Our Eco Biodiversity is being lost rapidly. The Loss of biodiversity ought to be the primary reason for Green Architecture. Buildings and Infrastructures are to design the strcutures with a restoration of biodiversity –Restorative Biodiversity design Biodiversity design,otherwise our future sustainability will be affected to the brink of disaster of out civilisation.

Carbon Trading

The Kyoto Protocol,1992 in the UN Framework Conventions on Climate Change but adopted in 1997 established the basis of Carbon Trading, Carbon offsets.
192 nation agreed to reduce Carbon emissions, which Identifies the 6 GHG gasses as 1) CO2 2) methane, 3) N2O 4) hydrofluorocarbon  5) perfluorocarbon and 6) sulphur hex-fluorocarbon. All these gases are referred to as Carbon emission, Carbon dioxide is the weaker global warming effect but the amount of it is the largest amount. Before the Kyoto Convention 2 Convention were held to establish the basis of Carbon emission, what is was considered as Carbon emission etc.

Carbon Trading Price Fluctuations

Protocols

The Carbon Trading has been defined in 3 conventions as follows:
a) Earth Summit-Conference on Environment and Development –UNCED, Rio 1992
b) United Nation Framework Conference on Climate Change UNFCCC( not binding due to no time limit was set by the UN
c) Kyoto Protocol, 1997
Carbon Trading is under the purview of the UN, Article 26 of the Vienna Convention on the Law of Treaties 1969 and therefore the Kyoto Protocol is a treaty
In Malaysia, the Ministry of Natural Resources and Trade is in charge of CDM. In Malaysia, 100 tonnes were traded in 2008, at RM4.8 Billion. I ton of carbon was  sold at RM48. The price of carbon rallied from US 25 – US 12 over these years.

Ways to earn Carbon Credits for Carbon Trading

There are a few established legitimate ways of Carbon trading , which are:
a) using PV solar panels as Carbon Offsets are made
b) using wind turbines as Carbon Offsets are made
c) designing Net Zero Carbon Emission buildings or Net Zero Energy Buildings
d) Managing a forest ( Tropical) or wetlands, as the soil and tree sequesters CO2 by using PV solar panels as Carbon Offsets is made
e) Investing in a Carbon reducing projects such as Renewable energy projects, Geo-Thermal, Biomass, PV solar panels, micro turbine and wind turbines.
How much can you gain by Carbon Trading?
A typical building as in a 100,000 sq ft of gross built commercial space up area can offset carbon 390 tons of carbon per year.
The financial amount you can trade is 390 ton per year xRM48/ton=RM18,720
Carbon Emission for Combustion Fuels
Coal…………………0,37kgCO2/kWh
Gasoline…………. 0.27kg CO2/kWh
Diesel………………0.24kgCO2/kWh
Light Oil…………. 0.26kgCO2/kWh

Talk 1. Targeting for  Net Zero Carbon Emission in Process and Product Design …Net Zero Energy Buildings
Synopsis of the Talk  Dr YewAi Tan

Oder a seat for the seminar now, by clicking here  Net Zero Carbon Seminar

At the UN Climate Summit in New York on 23 September 2014, the Prime Minister of Malaysia reiterated Malaysia's commitment towards reducing its carbon emissions, in terms of emissions intensity of its Gross Domestic Product (GDP), by 40% by 2020. This will be implemented by reducing carbon emissions through new policies on climate change and green technology. Under the 11 th Malaysian Plan, RM 2.3 billion has been set aside for green technology based projects. This pledge, originally made at the United Nations Climate Change Conference (UNFCC) 2009 in Copenhagen, Denmark, was conditional to receiving technological and financial assistance from developed countries. This year, Malaysia looks on track to hit the targeted carbon reduction emissions having achieved 33% reduction carbon intensity of its GDP. As GDP is the monetary value of finished goods and services, Malaysia will therefore have to grow its GDP without a parallel increase in emissions in order to achieve the 40% reduction.

The Climate Change problem will never go away on its own and ignorance on its seriousness is no longer an excuse for inaction. For effective mitigation

Net Zero Carbon and Net Zero Energy Cost

Net Zero Energy Cost Seminar

against climate change, there must first be acknowledgement that the burden must be borne by all. The next step will be how each and every one of us, the residents of planet earth, can help in reducing carbon emissions with a target towards achieving zero net carbon emissions. Before embarking on efforts to achieve zero carbon emission in process and product design, it is essential to be clear and familiar with the many terms and terminologies commonly associated with carbon emissions such as greenhouse gas (GHG) emissions, carbon footprint (CFP) , carbon capture, carbon sink, carbon neutral and energy neutral, etc. For example, CFP is defined as a measure of GHG emissions over the full life cycle of a process or product including the design stage, if applicable. It is the overall amount of not only carbon dioxide (CO 2 ) emissions but also emissions of other GHG such as methane (CH 4 ), nitrous oxide (N 2 O),chlorofluorocarbons (CFCs), hydro fluorocatbons (HCFs) and sulphur hexafluoride (SF 6 ) that are directly and indirectly associated with a product along its supply chain. GHG emission is an integral part of all systems of production and consumption, In the case of a process or product design, each activity within a supply chain process step which is involved in the production or design of the product must be analyzed to determine CFP measured in mass units (kg, t) of carbon dioxide equivalent (CO 2 eq) emitted. Through a carbon audit, any sector of an industry (e.g. palm oil or building industry) can systematically address environment-sensitive practices along the whole chain in the design and process of a product. One of the most important move that can be taken is to ensure that all products and services made and provided involve minimal carbon emissions. To arrive at net zero carbon emissions, emissions must be offset or subtracted and ways to achieve carbon neutrality will be highlighted in the paper. Suggestions on the formulation of possible mitigation strategies to curb GHG emissions and ways to target for zero net carbon emission by balancing emissions with simple negative emissions solutions such as tree- planting and the use of other more advanced technologies including the use of renewable energy generated from waste products, the sun or wind will also be discussed. The goal is to provide required information on the importance of our shared responsibility to reduce carbon emissions in the hope of ending the high emitting and energy-hungry practices of the modern world.

Talk 2. ACMV system design for Net Zero Energy Buildings in the tropics in the  Net Zero Carbon Seminar

by Dr Stellios Plainiotis

Net-zero energy buildings (Net-ZEBs) are a quantifiable design concept and an absolute solution to minimize the operational environmental impact of buildings. However designing such advanced buildings presents a challenge because there is no established design strategy to methodically reach the goal and many of the available calculation tools have limited applicability for Net-ZEBs. Appropriate modelling of building-integrated energy systems (passive and active) is essential for the design of ACMV systems and the study of optimal control strategies. These systems will play a major role in achieving the net-zero energy goal and need to be carefully selected, modelled, and sized for an optimum design. This talk focuses on optimizing active ACMV systems with emphasis on building simulation and parametric analysis. This presentation will review current design practice and tools for designing ACMV systems and presents methods employed by NEAPOLI to design ACMV systems in the tropics. It also discusses modelling issues and outlines the procedure used in several optimization case studies by NEAPOLI.

Talk 3: Achieving Net Zero Energy Status: the case of the Hospitality Sector in SE Asia

Synopsis of the Talk  in the  Net Zero Carbon Seminar by Dr Stellios Plainiotis
Oder a seat for the seminar now, by clicking here  Net Zero Carbon Seminar

Although the hospitality industry is responsible for only 2% of the world’s CO2 emissions, it makes an excellent sector for achieving Net-Zero Energy status  because energy  consumption  is  higher  than  in typical residential and non-residential buildings, so  there  is  a  larger potential for energy saving measures. Hospitality projects in Asia can benefit from reaching net-zero status through:

  • Energy savings and reduction of operational costs
  • Unique positioning in a highly competitive market
  • Improved image and service for guests
  • Access to a new “sustainability” market segment, both individuals and companies
  • Increased comfort as an added-value for hotels’ guests
  • Corporate Social Responsibility targets met; Environmental, social and economic sustainability.

There are however great challenges related to financing the additional initial capital expenditure and to  business model that includes a number of energy intensive operations associated to their customers’ comfort and expectations, therefore closely linked with their competitiveness and viability.  After presenting the fundamental concepts, design strategies, and technologies required to achieve net-zero energy in hospitality buildings, this presentation will discuss a case study of a Net-ZEB Hotel in Malaysia by NEAPOLI.

Talk 4: Generative and parametric design optimization techniques towards Net Zero Energy Buildings, Synopsis of the Talk  Net Zero Carbon Seminar by Mr Theodre G

Oder a seat for the seminar now, by clicking here  Net Zero Carbon Seminar

Net Zero Energy Buildings (Net-ZEBs) represent a new paradigm that radically changes the way we view and construct buildings. Our current practices, tools, and culture involved in the design and development of contemporary buildings are not entirely compatible with this new perspective. We are in dire need of new design paradigms that will allow the re-conception of the design process itself. NEAPOLI’s Research & Development efforts are focusing on two of the most important innovative design methodologies available today: generative and parametric design.

Generative design can be defined as an evolutionary process that charts the development of an original idea, searching quickly through all its possible permutations, testing different design configurations, learning and improving at each step. New design tools employed at NEAPOLI now allow cycling through thousands of design alternatives in small amounts of time, making generative design a very powerful approach especially for the early stage of design.

Parametric design can be defined as the varying of one (or more) building parameter(s) and performing a simulation to quantify that parameter’s impact. NEAPOLI employs parametric analyses to provide at least three valuable pieces of information:

  1. The optimal/near-optimal value of a design parameter, always in relation to other often competing parameters. If the performance metric for a particular parameter indicates that there is an optimum value, the design team may wish to use this value in the design, assuming it is practical, economical, and compatible with other design aspects.
  2. The relative sensitivity of a parameter. This is particularly useful when multiple parameters are compared.
  3.  The relative importance of accurately modelling a building system. The most care in accurate modelling should be given to the aspects that are most sensitive. Sensitivity analysis is a very important confidence building tool for NEAPOLI consultants.

This presentation will provide an exploration of these innovative design approaches, it will show how they can provide competitive advantages over contemporary processes, and finally share ideas and examples of their implementation in the design of Net-ZEBs.

 Talk 5: Net Zero Energy Design in practice: design optimization methodologies and tools Synopsis of the Talk  in  Net Zero Carbon Seminar  by Mr Theodre G

Traditional construction practice created buildings to meet current needs, without addressing how well they fit with the natural environment. Because they were lacking adaptive capabilities, they would usually require remodeling or replacement when use-patterns or external conditions changed, an approach that is costly both financially and environmentally. Net-ZEB buildings can provide solutions to this because not only are designed and built to produce all of their own energy, capture and treat all water, but they can also designed and operated to have a net-positive impact on the environment, including repairing surrounding ecosystems.

However new and innovative tools are required to achieve and realise that vision. While generative and parametric methodologies are gaining ground in both architecture and design practices, their practical use remains limited due to the lack of design tools equipped with generative and parametric capabilities.

This presentation will describe the current status of generative and parametric tools for the building design industry and how these are being used to improve building design. In a workshop-like manner, the audience will be taken, step-by-step, through real-life design examples showcasing NEAPOLI’s ‘box of tools’ paradigm which allows the development of highly complex and integrated models able to assess in parallel a wide variety of building performance and design issues.

Net Zero Carbon Seminar

By: Gregers Reimann

In a Low Carbon World, we will have to deploy on the dual strategy of energy efficiency and renewable energy. In this presentation, the focus will be on renewable energy and its stronger and stronger case as opposed to fossil fuels. Interestingly, renewable energy costs are starting to achieve grid parity. Moreover, once the true cost of fossil fuels is factored in, namely the external costs like (carbon) pollution, the business case for renewable energy becomes even better.

For Malaysia, biomass and solar energy are the most applicable conventional renewable energy sources, but once implemented on a big scale, they both take up significant land area. Therefore, apart from re-stating the importance of energy efficiency, this presentation will also examine how renewable energy can be integrated in our built environment without taking up ‘extra space’.
Highlights of this presentation include:

Referencing the recent IMF study on the true cost of fossil fuels and its astounding conclusions. For Malaysia, for example, if we were to pay the real cost of fossil fuels, the petrol should cost RM4.50 per liter, which is more than double of the current cost.

Calculations example of how much solar photo-voltaic panels are needed to cover the entire Malaysian annual electric consumption. The result may surprise you in a positive way.

Talk 9 : “Zero Energy / Carbon and Innovative Tropical Building Case Studies

Synopsis of the Talk in  Net Zero Carbon Seminar By: Gregers Reimann
Oder a seat for the seminar now, by clicking here  Net Zero Carbon Seminar

The biggest and cheapest carbon emission savings are found in the building sector. Therefore, the building sector will play a key role in achieving the low carbon sustainable society that experts are urgently calling for. This presentation will focus on Malaysian case studies of low energy buildings both for commercial and residential sector. The focus will be on the design strategies employed in the case studies, both with respect to innovative passive building design by working with the climate and with respect to innovative active design solutions for ventilation, cooling, lighting and controls.  The low carbon aspect of the presentation will focus on the operational energy, which constitutes the bulk of the life-time carbon emissions for most buildings. The case studies presented have achieved measured energy savings of 50% or more and often with an attractive short payback time from reduced monthly energy bills.
The presentation will also re-examine how to approach thermal comfort for people in an energy efficient way and with the added benefit of providing improved air quality.

Some of the case study highlights include:

Case study no. 1: Zero energy bungalow (2016) in Kuala Lumpur with innovative natural cooling system that lowers the indoor temperature by 2-3°C, hence, eliminating the need to use air-conditioning. In fact, the bungalow does not have any air-conditioning installed.

Case study no. 2: Innovative high rise day-lighting system (2015) in Kuala Lumpur. Even though the occupants engage the manual facade window blinds, the daylight system maintains 7-meter perimeter zone of the office fully day-light.

Case study no. 3: Energy efficient building retrofit project (ongoing) saving 50% of the energy consumption in part by a new approach to providing thermal comfort to the building occupants

Case study no. 4: Innovative energy efficient and low energy slab cooling as exemplified in two Malaysian offices buildings, the GEO Building (2007) and the ST Diamond building (2010).

Talk 11: LCA and LEED for Enhancing Energy and Environmental Performance of Buildings

Synopsis of the Talk in  Net Zero Carbon Seminar by YewAi Tan
Oder a seat for the seminar now, by clicking here  Net Zero Carbon Seminar

The orthodox goal of increasing housing for growing population needs is now slowly being replaced by a shift in focus to buildings that promote variety, access to healthy and clean air, and a healthy and ecological sustainability environment. This is driven by risks that climate change poses for human and natural systems.  Global warming, sea level rises and associated extreme weather events are now adversely affecting population health and will continue for centuries to come.

With over half the world’s population now living in urban areas, resilient urban housing plans will need to incorporate more extensive approaches to meet the challenges of a world imperiled by severe weather conditions resulting in floods and droughts.  Attention will be on enhancement of ecosystem health as well as the health and support of thriving urban environments.  The building and construction industry is known to be the one of largest contributors of environmental pollution.  According to the United Nations Environment Program Report, buildings account for a third of greenhouse gas (GHG) emissions, 25% of global water consumption and 40% of global energy consumption and resources.   The fact that this energy consumption in buildings can be reduced by 30% to 80% using proven and commercially available technologies accentuates the importance of greening buildings as one of the most effective ways to reduce the carbon footprint (CFP) of the building and construction industry.

The main objective of Green buildings is to reduce negative impacts and increase occupants’ health. Green buildings address issues concerning sustainable site planning, water and energy efficiency, conservation of resources and improved health, and the impact of buildings on health and indoor environmental quality.  The Malaysia Green Building Index (GBI), initiated in 2009, is based partly on USA’s Leadership in Energy and Environmental Design (LEED) but adapted to fit the Malaysian climatic conditions.

The LEED rating system is a voluntary U.S. based  green building programme which aims to “evaluate environmental performance from a whole building perspective over a building’s life cycle, providing a definitive standard for what constitutes a green building’’. In essence, the LEED method rates the energy and environmental performance of buildings and is clearly an environmental assessment tool.

CFP is a computed number which an industry can use as a baseline reference for improvement.  At the same time, the methodological tracing through Life Cycle Assessment (LCA) of the various sources of GHG emission in sustainable buildings will give a clearer indication on where mitigation steps can be implemented for GHG reduction.  LCA is also an essential component of building assessment as it is a step-by-step process for evaluating the environmental burdens associated with an activity, product or process.  The method, based on the life cycle of the activity, product or process identifies and quantifies energy and materials used and wastes released to the environment, thereby assesses the impact of those energy and material use and wastes to the environment. LCA is applicable to all system levels in the building sector. Each system has its own set of assumptions and limitations and each is designed to address certain aspects of environmental impacts.  An inventory of all inputs (e.g. energy, material, water used) into and outputs (final product, emissions, wastes)  out of the system will allow for calculation of impacts based on energy consumption, waste generation or other impact categories such as global warming or land use.   The approach can be used for the selection of building materials or for assessing the environmental impact associated with the physical building.  Therefore, in order to obtain useful information from environmental assessment of buildings, the rigor of an LCA approach can be used to support and complement the evaluation of LEED compliance.

Malaysia’s Green Diamond Building headquarters of the Energy Commission (Suruhanjaya Tenaga) of Malaysia in Putrajaya won Southeast Asia Energy Prize in 2012. The building, completed in 2009, earned Platinum ratings under Malaysia’s Green Building Index (GBI) and Singapore’s Green Mark program.

TOOL 1) Air Flow Analysis

CFD, Computerized Fluid Dynamics is a tool to analyze the flow of air flow and heat transfer within the building and in the external sides of the building. This studies can be used for Mechanical Engineers for air conditioning studies, for ventilation purposes for architects and the wind load on external cladding and external microclimate where heat island are detected and it can be eliminated by designing the layouts. These are some of issues CFD will address:
a) temperature distribution along the atrium, b)the adequacy of the diffusers for air distribution, c) adequacy of air conditioning diffusers and outlets for comfort, d)the adequacy of natural ventilation, e)the effect of wind speed in the locality affected by the shape of the building f) stale air islands are discovered.

TOOL 2) Wind Driven Rain, WDR

The negative effect of humidity and hygrothermal situation are predicted early, that which affects the durability of buildings. The covered area for the pedestrians, protection during a storm is studied. by studying the intensity and spiral distribution of driving rain.

Tool 3) Finite Element Modelling

Soft-wares such as Therm 6.3 and Window 5 are state of the art computer soft-wares that analyses details of building, windows, walls, sills etc to discover sources of  losses of heat (during winters) or sources of heat is gain(during summers)

This software was developed by Lawerence Berkely National Laboratory

Tool 4) Sun and Shadow Studies

The soft-wares are google sketch up,Ecotect,Rhino/Grasshoper, and Honeybee/Ladybug

Understanding the building sun and shadow will help to discover sides of the building that needs to insulated from heat gain or heat loss.The shadow analysis will help to evaluate the effect of window and shading devices that keep the building comfortable.

What is Modern House Plan?

The Modern House Plan  is clean-lined , sharp and crisp-edged using shapes that are sophisticated looking homes.and ,functionally focusing first and foremost and primarily using a modern material and exposing the structures or using the structures in a cunning way .

The modern house has a smooth and shiny surface ,everything ,maybe even white and balanced.

Modern homes are very elegant,neat ,sleek, precise and are constructed to the finest of a quality of workmanship which is a beauty by virtue of this attribute.Taking the cue from the motto,” God is in the detail”. It uses the most up-to-date techniques of construction and using new ideas of materials and inspiration from ;modern art and graphic and using equipment for constructability of modern forms.

Modern homes are greatly simplified taking the cue from the motto “Less is more”, giving way to a clean aesthetic where materials meet in simple, well-executed joints. Modern house was most typically using the concrete structures using a flat or broad low-pitched gable or shed roof.

Exposed structure, an expressive using modern materials such as single panel glass cladding, silicone and , and the incorporation of landscaped areas into the house and on the top of the house, Living roof concepts where landscaping are placed on the rooftop where it is extensively waterproofing to keep the roots from uprooting the waterproofing.

Modern Architects ?

In an architectural sense, Modern architects were Louis Sullivan & Frank Lloyd Wright( US), Otto Wagner (Vienna), Victor Horta ( Brussels), Le Corbusier (France) and Antoni Gaudi (Barcelona). The German Architects -Ludwig Mies Van der Rohe and Walter Gropius organized the Bauhaus School that was a great influence on the modern Architectural movement.

However, for the purpose of this article, we would like to refer to all homes that are presently being used as a Modern house .

modern house floor plans

Green and Sustainable House floor Plan

The features of Modern House Plan are:
1) cantilevered structure

A cantilevered structure is a feature that is typified in modern homes, It may be used as a counter balance. A concrete cantilevered structure slab extended from the house, without any support from a pillar or beam, is useful to provide effective shading. The modern house is a flat or broad low-pitched gable or shed roof and this roof may also be cantilevered.

2) Shape and Forms of Modern House Plan

Shapes and the forms of houses are based boxes shaped, or interlinked boxes and the vertical forms are juxtaposed against horizontal elements for dramatic effect and illusions effects.

3) Materials of Modern House Plan

Materials are often used in well-defined planes, Modern house exterior wood is also stained so that the texture and character of the wood can be expressed. some modern home uses of synthetic sidings added steel structural support.

Modern homes use traditional materials in an interesting way, where materials such wood, brick, and stone are simplified lacking the traditional ornaments, in ways where architecture reflects a modern aesthetic. Traditional horizontal clapboard siding is used as vertical board cladding used in large planes. Stonework and brickwork are simple, fascinating ornaments removed, and used in rectilinear shapes and extruded planes.

4) Symmetry of Modern House Plan

Modern home has Asymmetrical exteriors with curved walls or unusual angles and shapes.Forms may tend to be organic breaking away from the rigid, regular,symmetrical as there are studies that shows much benefits accrue from organic forms, read here.

5) Exposed structure forModern House Plan

Exposed structure and an expressive use of modern materials and columns exposed to draw aesthetic in the exposed structures.
Exposed concrete block, bricks, exposed wall are left bare finish to reveal the true character of the structure in lieu of a finished material.Concrete floors, plastered wall are stained and exposed, long-span steel trusses permit open column-free spaces, and service pipes such as also exposed.

Modern home adopt the new “skin-and-bones” architecture for their emphasis on steel structure and glass enclosure and vice versa.

6.)Net Zero energy Homes with Green and sustainability House plans

Comfort  with minimal use of energy such as Radiant heating systems enhances human comfort,   orientation with respect to the solar path, super insulation of the building, sensors to save energy, BAS to manage the building for maintenance and PV solar panel. Wind turbines ,geothermal energy and biomass energy to enhance the sustainability of the environment,

Modern home uses of large sheets of glass in effect bring exteriors of building’s site into interiors of the building, with dramatic views and introducing and harvesting natural daylight deep into the interior of homes

Modern home has natural and smart landscaping. The best modern homes are energy efficient. They are oriented to take advantage of natural forces to generate renewable for passive solar heating in the winter.

So ! What is a Beach House really?

Beach Houses are the serene homes often located near the beach and shorelines. Typically they are also houses are located in the mountain areas with view of near the waters of the sea shores.

It is also like cottage houses, which are places to spend the holidays and enjoy the vacations.

The typical features of beach house plans describe the houses with large verandas with a wooden structure. Spacious beach house plans also include houses built with a magnificent view of the beaches. The rooms such as breakfast room, master bedroom, the living room and the guest room have a circulation access to the decks. The rooms may be given a spacious areas.

What are the distinguishing features of beach house? 

Beach house interior design tends towards simpler and exclusivity of spaces is removed in comparison to the conventional and traditional concepts of home.

The ocean is a great source of inspiration for many different beach house design ideas. The shape and forms of the ocean may affect the form of the beach houses. The design style of beach house is a real favorite among the people alike is the Contemporary Coastal style. It’s a style that essentially reminds us of the beach itself.

It really creates an atmosphere that is cheery, airy and relaxing atmosphere

Beach House Interiors
The one of the most exciting parts of a beach house is all of hardy and robust types of furniture pieces that go all throughout the interior of it , generally made from organic materials and natural fibers, that reflects the beach life as much as possible. Rattan furniture,( wicker ) beds made of natural oak frames, finished bamboo blinds and dotted with canvas chairs., along the deck and umbrellas fixed to sun bathing seats.

Interior decor for beach house never has to be expensive and should be more fun.

As a means of interior decoration, sea shells tropical trees that evoke the ambiance of warm as palm trees, sea shells, sea fishes, star fishes, the boat scenes, ships. tropical fruits juices etc may be ideal to create the ideal interior setting of a beach house.

Curtains or drapery that is rather reflective of the nature, seas or clouds and sunny beach-like in nature, can help to diffuse natural setting and mood of beach outdoors.

The large single paneled window, granting the views of the seas and the outdoors may help to create the out doors feeling in doors in a graceful manner,

Utilize the Mermaids Indoors as a decor of beach house and even in the outdoors as this has an immediate sense of outdoors.

Net Zero Energy concepts

Bring In More Natural Light as to create the beach ambiance but it is sensible to utilize net Zero energy concepts as a green sustainable feature to reduce the energy from the grid. And sources of energy may be a hybrid of wind turbine and a solar panel that pays for the finance of the second beach . energy may be a source of earning some finance as the house may be left unattended too during the off holiday season, when renewable energy may help to finance the second home.

It make sense to harvest the sun where the lux level is about 140,000 lux at mid day and whereas the light for task level is only 350 lux.

This home was built with lots of glass walls around it but carefully to reduce the heat inside the beach house,

What are the types of beach house?

There are 3 types of beach houses, namely:

  • Urban Beach House
  • Sophisticated Beach House
  • Modern beach house

Wind Turbines

This is the energy that helped the pioneering Americans to conquer the frontier, where, every village and farm was dotted with a wind mill .
Wind energy is free and clean and available in abundance and created without having to burn fossil fuels or manufacturing process that damages the environment.

The estimated energy that can be harvested in the wind is 20million MW world wide according to World Metro logical Organization.

Advantages of wind energy:

a) It is clean and does not employ fossil fuel
b) It can be installed in great speed unlike hydro energy
c) It is cost less those solar or any other sources of energy. It is about 3 cents/kWh compared to 5cents for coal powered plants.
d) It is modular system and can be added upon
e) It does not depend on the sun and the time of harvest in not restricted to the day but wind may be harvested during the night and storm situations when there is wind. About 90% of the time the wind turbine can harvest energy. The minimum wind for wind to be harvested is getting lower, presently technology to harvest wind as low as 5m/s
f) The cost of wind energy does not depend on the prices of fossil fuel or the market forces.
g) It is 60% efficient compared to 20 to 40 % efficiency of Photo voltaic panels.

The offshore wind energy is becoming more popular in UK and in the US, the following are some of the projects:
1.)Thanet off shore wind farm
Total off shore wind energy off the US Atlantic has the potential to take off the fossil fuel by 30% total energy off the grid.
2.) Vatenfall off shore wind farm
The wind turbine in England supplies energy for 200,000 homes built for £780 m it has 100 no of turbines of 380ft over 35km2 , Vatenfall, a Sweddish company secured the project

3. Block Island Wind Farm
Google has scheduled to construct along the Atlantic ocean for deep sea wind turbines along a 35m transmission line to generate electricity for 17.000 households- Block Island Wind Farm will tap the enormous energy of the Atlantic coastal winds.
http://www.washingtonpost.com/news/energy-environment/wp/2015/07/27/a-milestone-for-wind-energy-work-underway-on-first-offshore-platforms-in-u-s-waters/
4. Wind farm in Yorkshire England
The world largest wind farm in Yorkshire England will provide energy for 2,000,000 households. English pounds 14.5bm. Wind farm, comprising of 100 turbines of 380m high {115m} and spanning over an area of 35km sq{13.5 sq mile}

Wind energy is proportionally related to the following factors:
a) Wind speed
b) size of wind blades
c) type of blade system
d) the height of the wind turbine

A modern wind turbine produces electricity 90% of the time, but it generates different outputs depending on the wind speed.
a turbine’s best efficiency is 40% at a wind velocity of 9 meters per second (about 20 mph), it will be 40% only at that wind speed. At all other wind speeds it will be something worse.

Consideration for design

The wind should be 5-8mph, the height of the wind turbine is be above the surrounding by 10m to receive unobstructed wind supply, the supply of wind is uncertain but is available during the night, cloudy days, when the PV panels don’t work, complementing with the PV solar panels as a Hybrid system, may be a good consideration as they compliment each other. Location of site near the sea coast will make wind turbines a more viable option by the strong wind

Some interesting facts
The amount of energy the world needs is 155,500TetraWatt per Hour, which is 155.5x1012KwH.

The amount of energy the earth received from the sun is 10.3x1017KwH which compared to amount of energy that is sent in not 1%, not 0.1% but 0.015% which is a pittance of a proportion. Conclusive is to say that this calls for a case of renewable energy, if we could tap the energy from the sun, the energy we consume is hardly anything to think off in comparison to the environmental damage we create by fossil fuel. The energy of the sun is used for converted into wind, wave, movement of air and the vegetation in it.

Moreover the amount of Geothermal energy available in the US , according to a report produced in Harvard ,is sufficient to supply the US’s energy for 2000 years.

Green and Sustainability solutions for our Cities

All over the world the we generate much domestic waste from New York City to New Delhi, a call for reduction of waste should be in calculated by Architects. Buildings are the sources of waste and it should be reduced, reuse and recycled otherwise we will find ourselves living among the waste.

Waste designs failures

Failure of Disposal Waste designs by Green Architect

We can learn from nature how waste is processed. The spider eats up the waste webs , plants consume the Co2 we dump, and the bacteria consume our waste, the earth does not have a dump center. But our domestic waste is left to decompose and we are running our of land fills as the waste takes about 30 years to decompose and diapers takes 500 years to do like wise, to a stable conditions.

We generate much waste as the figures listed below reveal; Architects can do much to solve the problems.

  • New York City generates as much as 36,200 tones of garbage every day.
  • London city’s waste can generates 9,100 tones per day, equivalent power to power 2m homes
  • The amount of domestic waste( Municipal Solid Waste) generated is 2,400 tones per day in Kuala Lumpur
  • New Delhi generates about 7,000 tones of waste per day

In the absence of a comprehensive Integrated Strategic MSW Plan all over the world, Architect can forge a plan to reduce the waste at the source-the building, where 95% be recovered and recycling the aluminum and steel and the wet waste to be reprocessed composted for reuse. Or biomass waste power be generated and re-supplied into the grid.

Consideration by Green Architects  in Domestic waste( solid) disposal

As Green Architects our responsibility lies in designing for Waste Collections Centers (waste dumps) where rubbish is sorted out not dumped. Sorting should be done at every floor of the office tower so that it is not dumped at the waste dumps but easily sorted out early at the source.Sorting should be wet waste, paper, cans and bottles waste.Every waste dump at every residence, industrial buildings, resorts, hotels, commercial centers are
to be designed like wise for waste sorting.

Consideration by Green Architects  in Domestic Waste water disposal

As Green Architects we ensure the drains are built properly ,the collapsed drains can be a source of to breed mosquitoes. Bios vales may be considered to replace the external drains as the waste water can be recycled as portable water even for human consumption.

 

Consideration by Green Architects  in Wet Waste disposal

As Green Architects we should ensure the food waste ( wet waste)are not dumped into the drains which help to breed rats rampantly, liters in drains can encourage the rat population to breed.

Wet Waste mixed with the landscape waste, should be sent to the composting yard at every building which should be reused as compost manure which is a better manure for the landscaped areas as it stabilizes the acidity of the ground helping to maintain Eco balance in the ground, See the Edmonton waste center in Canada, an example where waste is recycled as manure. We can start small composting places at our every building sites . If it was a campus style development or a housing scheme where wet waste generated could be massive amount, a Net Zero Energy Architect would design for generating  biomass renewable energy from the wet wastes.

Consideration by Green Architects  in Construction waste disposal

Construction waste should be minimize by using construction systems that reduce wastes such as IBS system or waste is recycled within the site, ensure the contractor reduces waste in the first place. As architect it is our responsibility to design buildings as a waste sorting, reducing and recycling at the source than to shove the problem to city municipalities to solve green and sustainable issues before the waste sites swallows our living spaces.

The common misconceptions about Net Zero Energy Building as reported by Wikipedia: A zero-energy building is a building with zero net energy consumption, meaning the total amount of energy used by the building yearly equal to the amount of energy created on the site. This is only partly true in the early day when this principle was first conceived. And to this day this is the common misconception among many .

In fact the energy (the energy pie) consumption is reduced to about 80% of the conventional consumption and then the balance 20% of the balance of energy is made up by the renewable energy, the renewable energy may be sourced from solar Photo Voltaic panels, geothermal, wind turbines or biomass energy.

This article is about the case for Net Zero Energy Building and why we should perpetuate this goal: There has always been some anticipation of imminent disaster that we need to be cautious about, such as the ones illustrated below:

  • Recently Bill Gates asked the, If some cataclysm, all scientific knowledge was destroyed, what is the one line fact that next generation of humanity needs to know!
  • About 50 years ago the question schools debated on was the earth was depleting its resources and the end is near.
  • Recently with the major obvious undeniable weather changes and so called global warming in the Arctic glaciers!

There have been many calls for Green Sustainability movement called -Going Green, thinking this is the solution to the impending juggernaut disasters. In reality the solutions in Green are really superficial and will not help very much with self reliance and self sustainability.

  1. When Japan faced the Fukusima earthquake that destroyed the Daiichi nuclear plant they experienced a power crisis that awaken to the importance of energy conservation and lead to the need for Net Zero Energy Building A new standard for construction was implemented to this end of 2020. We need Net Zero Energy Building for our future survival.
  2. One would think that even this should not be the goal would not suffice unless there was a total independence for electrical consumption and not be dependent on the utility company for energy consumption should be the ultimate goal, with Net Zero Energy Buildings which is off the grid. Net Zero Energy Buildings tend toward self reliance.
  3. Net Zero Energy Buildings reduced the waste in as much as 80% purely on the basis of passive strategies and shading, smart landscaping and other active strategies. The buildings are more efficient and low energy consuming where not wasting is reduced and resources and minimized;
  4. By installing Net Zero Energy Building you have clear conscious that you are  morally doing the right thing, stopping the unwanted wastage.
  5. By installing Net Zero Energy Building, you indeed saving money , which could be used meaningfully elsewhere, imagine the regular monthly bills amounting to USD200 could be used meaningfully else where.
  6. By installing Net Zero Energy Building you are responding responsibility to the climate changes demands that us undergoing world wide by reducing the foot print and closer towards becoming self sustainability for our future survival..
  7. By installing Net Zero Energy Building you have Value for your rent able space or value for property, Developers will find the Net Zero Energy Buildings as a marketing tool to bargain for higher rental compared to Going Green for certification. Green building do not receive higher rentals as tenants do no see the need to pay higher rentals for Green sustainability certified building.
  8. By installing Net Zero Energy Building, you secure government grants and benefits from most governments of the world.
  9. By installing Net Zero Energy Building you may receive taxation incentives
  10. By installing Net Zero Energy Building you don’t have to pay the monthly electric bill
  11. By installing Net Zero Energy Building you are making the buildings, cities ,world economies more efficient and  enhances the productivity of the  individual and collectively at large.

Here are reasons persuading for the case of Greening our Cities and Green Ecological Biodiversity for all Architects to be informed.

Reason 1-Remove the Heat Island effect by Green Ecological Biodiversity
It is known from research that the heat island effect is reduced as there is more green vegetation in the surrounding, the ambient temperature is lowered. Building aprons around the building which tend to conduct the heat into the building, therefore it is best to use grass Crete or turfs at the building surrounds in lieu of aprons. Road pavements should be replaced with grasscrete.

Reason 2- Reduces your energy consumption by Green Ecological Biodiversity
Smart landscaping reduces the energy consumption in the building, where it is primarily used for shading and warding off the heat from the building and in redirecting the cold wind winters away from the building will help to reduce the energy consumption by 10 to 50 percent of the energy bills. Shading the air conditioning units will help to improve energy efficiency. Read on save energy by landscaping.

Reason 3- Reduces pest controls and Waste by Green Ecological Biodiversity

compost

  • Pest controls –Green Ecological biodiversity will certainly go a long way to reduce pest controls, such as reduction of mosquitoes, rats which is a prevalent problem from New York to Singapore. In NYC which is a concrete desert , which has little trees resulted in an ecological imbalance of rat population, which as large as the human population in NYC. The problem arising from this imbalance is rat related diseases, oriental mites, etc. The solutions may be to enhance the Greening the city with Green ecological Biodiversity.
  • In the recent Greening of Singapore City, which was to green the city but failed to keep ecological bio diversities in place is keep away the bird and bats from the city, which resulted in an increase of mosquitoes and rats. The bird and bats eat up mosquitoes and rats and help to keep the balance. And eventually the recourse was to increase pesticides to kill the mosquitoes which in turn affect the water ways. The solutions to these cities going Green Ecological biodiversity.
  • Humus compost Waste– the waste from the Green landscape can be converted to natural humus compost, natural manure which helps the soil acidity in balance, healthy soils and keeps the bio-tic cycles( worms and living organism) of the soil in balance. When petrol-chemical based fertilizers are introduced into the soil, it destroys the worms and destroys the balance of the acidity of the soil and harden the ground and destroy the productivity of the soil whereas the compost based manure created by plants builds and keeps the soil soft and moist with a Eco balance.
compost bin

Reason 4- Increase oxygen content in the air by Green Ecological Biodiversity
Oxygen is necessary for our bodies in the following respects: a lack of it creates a tendency toward committing suicides, In Utah there is an suicidal epidemic due to the lack of Oxygen in the thin air, and an aggressive greening strategy of Utah city will certainly help to reduce the thin levels of Oxygen in the mountain tops air.The green ecological biodiversity will introduce more oxygen into the air.

Green ecological biodiversity

Green ecological biodiversity cycles

 

There are many hundreds of other reasons why Oxygen is needed – for brain developments, speedy human body recovery, reduce respiratory diseases, improves immune system , which are emphasized in the alternative medicine .

Reason 5- Improves air quality by Green Ecological Biodiversity
Green trees ionizes the dust and the dust from the air falls to the ground and thus helping to keep the air scrubbed, fresh for human use.

Reason 6- Reduces the air pollution by Green Ecological Biodiversity
Further more the pollutants such as SO2, NO2 and Carbon Monoxide is removed by the trees and helps to keep the air refreshed

Reason 7- Reduce stress and helps recovery and sick leave by Green Ecological Biodiversity

  • It was discovered from researches that if beautiful scenes placed in hospitals bedrooms helps patient recover 30% faster and uses 30% less medication for recovery. This goes to say the same for homes and offices; we are resilient from the mental and physical stresses that we are inflicted at work by having green scenes in our building s and cities.
  • Research also reveals that the no of occupants taking sick leave is dropped with green ecological biodiversity. This will help to enhance the productivity of the staff and people.

Reason 8- Increases the value of property by Green Ecological Biodiversity
The investment on Green ecological biodiversity comes with an increase in the value of property . This based on the Green of Singapore resulted in overall increase in value of the city.. I refer to landscaping with Green ecological biodiversity and and not the “Go Green Certification movement” ( such as LEEDs, or Mark, GBI certification). A developer complaint that he does not get higher rental by having invested on Platinum certification by Green bodies.

Reason 9- Improves the presenteeism, decreases absenteeism and sick leave by Green Ecological Biodiversity
Research reveals that greening with landscape within the building and in the surrounding will tremendously improves the quality of life and decreases the absenteeism of the workers and tenants working in the building and this helps to increase the productivity of the occupants.

Reason 10-Improves the water quality by Green Ecological Biodiversity
As rain water is treated in the blue infrastructures that work in complement with the green infrastructures, water is stored and recycled for our consumption by water hydrology, which in turn reduces waste water and polluting the rivers. Bios vales are used to clean up the water, reprocessed and recycled for consumption even as portable water.

Reason 11Self Reliance and self sustaining by Green Ecological Biodiversity
The forest does not need human care such as watering the forest; neither does it need insecticide and pesticides to survive. We can learn from the natures bio-metric to be independent self sustaining and self reliant. If we can establish the green ecological biodiversity of plants and landscapes, biodiversity of the animals that inhabit the landscape and biodiversity of the Eco cycles that help symbiotically one cycle to another for survival can we be self sustaining and self reliant. The fish in a water tank, with enzymes, bacteria, fungi, green weed and the snails is self reliant. The weeds produces O2 for the fish to live on, which in turn produces C02 for the weed to live on, the enzymes and bacteria eats up the waste of the fish and keep the water clean. The symbiotic relationship exist and so should we as Architect do likewise for our future survival and self reliant sustainability.

Haze in Singapore

Can Green and Sustainability strategies solve the Haze in Singapore and Indonesia

 8 valid reasons to go Green and Sustainability and the 8 valid weaknesses in the Green movement principles

Here we discuss the flaws in the Green and Sustainability movement that is catching on so rapidly world wide.

Reason 1- Sustainable planning
The cities and buildings are planned well for reduction and recycling of waste , energy efficiency, cleaner air within the office, and clean water for consumption, The green architecture is sustainable-sustaining the existing the environment for high quality of life well planned for the sustaining of life

Weakness of this
It is a weak attempt to solve the larger problem such as domestic waste, improve the life in urban living, improve the air quality or improve the poor water quality as they portend to improve. It should be aggressively attend to the issues rather to tend to it superficially, for instance” Can the Green and Sustainability stop the haze into our homes”

Reason 2- Waste
It will reduce outlandish waste in our environment, which is a serious problem as the land fills are full and the waterways are polluted by the landfills which return into our consumable systems dangerously affecting our health.

Weakness of this Green and Sustainability principle:
Waste should be removed all together and not reduce, but reused and recycled completely. In nature what waste we produce as CO2 in the air from our breaths is converted to O2 by the green landscapes. All waste from domestic and industrial waste should be like wise treated completely obliterated or reprocessed to useful matter.

Reason 3- Energy Efficiency
The buildings are energy efficient and installed with higher performing systems to reduce the energy consumption.

Weakness of this Green and Sustainability principle:
The Energy consumption should be Net Zero Energy Building and not a weak attempt to reduce energy consumption. And more importantly removed the dependence on the Grid. Wind turbines should complement with solar PV panel and combined with geo thermal energy. When there is no energy from the sun at night the wind will compensate for supply and when both fails to supply in case the eventuality of a disaster, geo thermal could be the alternative supply of energy.

Reason 4- Air quality
It helps to keep high air quality, which controlled and regulated which is improves healthy living environment but does not improve the haze or reduce the dust in the air.

Weakness of this Green and Sustainability principle:
No air quality is really improved; it is a real attempt to temper with air quality. The air is polluted with CO, NO2, SO2 or dioxin should be cleansed for consumption. There are no real attempts to even address this problem.

In the event of a Haze,( as in South East Asia by the recent burning of trees in Indonesia, or volcanic dust in the air etc) Does the Green building cleaned the air that we breathe in! No! It is not. One should reprocess air to remove the dusts, the pollutants, the hazes and bacteria and Viruses, in the air for use.

Reason 5- Water quality
It helps to reduce the wastage of portable water but not improve water quality, As much as high air quality the water quality will have a direct effect on the health of the residents.It focuses on the rain water harvesting.

Weakness of this Green and Sustainability principle:
Portable water is reduced, rain water is harvested but water in the pipe is contaminated, the water should be harvested for consumption, water from the underground for consumption should be considered as an alternative sources as supply in an eventuality of a drought of off seasonal weather changes affecting the water supply.

Reason 6- Reduces Energy consumption, Saves Resource, Reduces Waste
Every person is conscious of reducing consumption, waste and a new life style of economy. Material made from recycled Waste material is favored .Domestic waste is reduced, paper is not throw away, but either reused or avoided from being used.

Weakness of this Green and Sustainability principle:
Waste is reduced but not totally eliminated. It is said that the spider eats up the web waste and in nature there is no waste. Organic matter is recycled into inorganic matter,which is consumed again into the system.

Reason 7-Innovation
Creativity to think out of the box is granted some point for qualifying for the green certification.

Reason 8-Reduces long term cost of living
It does not cost much for now and it will eventually reduce the cost in the future and some propose that cost should not be factor; the cost of human life should be saved at all cost, as future of human life depends on sustainability.

Weakness of this Green and Sustainability principle:
In reality there is no reduction of cost in the future as the cost of sustainability is always higher and this is a cost already into the future and therefore the cost does not reduce in the long term. The argument that sustainability saves life to justify the high cost now is a fallacy.
In reality there survival of the human race does not depend on rainwater harvesting, pv solar panels etc but by eco biodiversity, net energy building off the grid and total self reliance as in the biometric of nature.

Reason 9-Sustains Environment for the future
In reality all the above principles as and the argument has been flawed

Weakness of this Green and Sustainability principle:
Green and landscaping not an essential feature of Green and Sustainability Architecture

  • Issues not considered in Green and Sustainability Architecture
    The ecological balance is not considered as we live in a eco system and the environment has taken a bitten and if it fails our survival will be at stake,
  • Sewer waste is not at all in design consideration. Sewerage and domestic waste is processed and recycled into the environment as in The Edmonton Composting Facility – Canadian recycling plant where human waste is recycled into manure for the city use.
  • Waste waster should be recycled as it is done in Singapore for human consumption.
  • The Net Zero Energy calls for total reduction of energy consumption which is not merely touching on sustainability, but attaining higher levels of Green and Sustainability. If we are able to be off the grid our sustainability will be even better still as self reliance is attained.
  • How can the Green and Sustainability help in the smog that polluted south East Asia with the recent spate of burning in Indonesia. In the light of the haze that is not considered, haze is a serous issues in China ( pollution from the industrial waste, in Singapore, Malaysia a result of burning in Indonesia)
  • If a disaster like a Tsunami where the power grid was destroyed, or a volcanic exploding dust in the air cutting of the suns rays for months, a blizzard of rays from the sun hit the world how can we survive this independently and be self reliant in the midst of catastrophic disaster.
  • The forest is sustainable and self reliant where no human care for treatment with pesticide or insecticide or regular watering is needed but it is self reliant surviving on the natural rain water unlike our farms where pesticide, manure, insecticide and regular watering is needed for its sustainability. We can learn from the nature’s Green and Sustainability as it is because of its biodiversity where one depends on the other and so should we live together with nature’s ecosystem. Read further on why green landscaping can help our sustainability.

Indian House in Goa

Indian House in Goa

It is hard to put in a nut shell that what and which constitutes Indian house design. India has been ruled by the British, Afghans moguls, that Indian house designs character has not been defined by these colonial master. or rather the British learn much words from the Indian culture( words such as shampoo, lantern, bungalow, cantonment, canoe, cyber,etc)

The houses in the North of India is not different from the houses in  South neither  were they any different form homes in the East – nor the West. However some enclaves in Goa and Pondicheery had remarkable difference because of the Portuguese and French influences for a much longer period of time than rest if India.

The Royals(refereed to as the Raj) lived in huge palaces where their wives and nuclear family lived in. In most places there were a large central courtyard where royal functions took places , where guards paraded with the elephants and a place of ceremony for the Raj. It was heavily guarded with one main entrance and with secret passages for Princely families to exit during wars. Water supply was secretly duct-ed underground to from the mountains for consumption at the Palaces .These water were designed for fountains in the gardens and dropped along window openings to allow the wind to pass through creating a cool breeze into the courtyards. the Net Zero Energy Architects should note that the passive designs were traditional used in the ancient architecture of India with respect to cooling with water and massive walls were good insulator of heat during he summers.

While in the courtyards held functions, the children and the wives were not to be seen in public spaces, they watched the function form hidden rooms from above the courtyards. The word Bungalow, is an Indian word adapted by the British for single storey house in large compounds.Landlord lived in Bungalow whereas peasants lived in Villages. These Bungalows were places where the rich landlords lived in.

Traditionally this bungalow , Indian House Design patterned after the palaces of the Princely palaces-courtyard house were common. The bungalow was elevated above the ground which led to an central hall which led to the master suite on one side, and to the visitor’s room on the other and the main dining hall.

Check out for some great design of Indian houses at http//:www.sda-architect.com The dinning hall had view of the central courtyard which was visible form the master suite, and all the other bed rooms. The maids quarters and the kitchen were at the end of the courtyard. A corridor led to the kitchen that butted the courtyard.

 Indian had a great love for their Gods and devoted to their gods in Temples ,and housed their gods in Indian design Temples. The palaces had temples and offered sacrifices to the god before going to war. They offered gold, precious stones, diamond, jade etc to their God when they were victorious in the wars and business ventures. These offering were held in Temple

Treasuries chest vaults.

The Temples were built in granite stones, sometimes mountains en block were carved and chiseled out to form the temples in the South of India. Use of precious stones in the temples were quite normal in their devotions.Marble for surface treatment was also common as it was found abundantly eg the Taj Mahal.

stone work on Indian places of worhip

Houses in the villages were usually had a front terrace where the folks sat out in the evening for a yarn.On entrance it lead to a common hall which was like Living room and Dinning room combines. There were rooms in the rear for the privacy of living.

In the Mohenjo-daro the civilization it was known to have been built in grid lines and the houses were known to have public sewer lines and common utilities. But with the advent of rapid modernization  and urban migration   during the British rule the  these urban planning once in greatness was  lost.where the focus was not exploiting the industries of India rather than planning the cities for urban living.

The Challenges of Net Zero Energy Building Architect

The Challenges of the Building Architect is greatly increased as the Knowledge that an Architect should imbibe is already a difficult and a broad one.But the additional roles of the Net Zero Energy Building Architect. for now and in the future is becoming even a more arduous and a difficult journey to undertake and to become a Net Zero Energy Building Architect.

Building Architects are becoming acutely familiar with the need to produce high performance energy buildings in the Green and Sustainability certification Requirements by the certifying bodies such in LEEDs ( USGBC), GBI (Malaysia), Green Mark (Singapore), Passivehaus ( Germany) and Zero Carbon( UK)etc

There was much accolade and hue and cry when Pyramid Building in Putrajaya attained the Platinum certification of GBI, all over the world. The achievement of sustainability and low energy consumption buildings is only the beginning of a greater goal of being organically independent. (read below) In reality achieving a level of sustainability is only the tip of the ice berg.

Net Zero Pie

Energy Pie

Energy consumption can be minimized by using the principle recommended by Ashrae 98.1 and Living Challenge. Modern technology makes it possible to produce Net Zero building, it is no more a fantasy for Net Zero Energy Building Architect .This is possible for high rise building and large scale commercial developments.Read on

Net Zero Energy Building Architect should be able to meet the challenges the climatic situation poses, as necessity is the mother of invention. Architects now have found relevance in the world with sciences and not merely delve in the realms of creative and artistic world.

 

Net Zero Energy Building Architect

Net Zero Energy Building Architect knowledge should be extended to the world of Building Physics and  ought to be able to:

  1. Provide an integrated procurement system with the Net Zero consideration in place at the outset. Integrating the Net Zero component into design at the outset of schematic stages, which conventionally is never done
  2. Be familiar with the technologies that enhance the reduction of Net Zero and those qualify Energy Star Renewable energy types such as Photo voltaic systems. Solar thermal systems. Wind turbines, biomass harvesting, geothermal heating and cooling systems and day light harvesting, chilled beams
  3. Familiar with Building Physics of the heat gain, the thermal heat gain, the sciences of heat (conductance, conductivity, specific heat gain, the psychometric chart of air characteristics of moist air), Heat wheel and recovery, enthalpy wheels, daylight factors, Resistivity, energy modeling, solar analysis. plug load, peak loads,
  4. Familiarity with software’s such as Ecotect, Vasari, Therm, design studio etc
  5. Familiarity with standards that govern the Net Zero Energy Building such as Ashrae Standard 90.1, Building codes established by Calgreen, IgCC, Standard 189
  6. Familiarity  with the requirements of certifying programs such as LEEDs, ( USA) GBI(Malaysia), Mark standards( Singapore).

The definitions of Net Zero Energy Building is defined by the NREL, read definitions The highest of the goals of NZEB is the Zero Energy Emission (Carbon) which is difficult to calculate and achieve. This goal is more difficult to achieve that Net Zero Cost.  There are many professionals that are pushing the agenda on Net Zero such as Architct MacClay, many should emulate stand and help to move this principles forward.However the our future with Green sustainability and Net Zero is not enough, we need to be ecologically well balance, ecological biodiversity integrated benignly and furthermore for our survival be organically dependent( read below)

 

The Future with organic dependence

The future for Net Zero Energy Building Architect will depend on how we look to nature and learn the bio metric of nature which does not waste, where waste is reused by others ecological systems.The forest does not need manure, pesticide or insecticide neither watering for survival. They are organic and independent from the external sources for survival. The Forest is organically independent. I wish to coin the term organically dependent

This goal is to be organically dependent of the utilities provided by the National Utility providers for electricity, water and waste disposal etc.

As much as the US should be minimizing the dependence of oil from the Middle East, so should we be in every aspect of maintain and achieve independence to outside sources.Imagine we had a Tsunami as in Japan, our total dependence on the Utility companies can pose a great danger, if the Tsunami was worst than it did, Japan may have been wiped out the world power.

Our long term survival depends on our independence from the external sources. This principle is greater than the sustainability of building which is a trend through out the world.

For one to be organically independent the following should be considered:

  • Energy consumption should be produced economically at the site or building. which we have defined as Net Zero Energy Building.
  • Waste should be saved form the rain harvested at the site and reserved at the site for use where water is not supplied form external supplies. Options such as pumping from underground wells should be considered as a last fall back on reserves when water in the store runs out. Rainwater can be stored underground using Biosvale storage systems.
  • Waste water disposal should be recycled for reuse at the site. Portable water for drinking and use at the site should be harvested at the site.
  • Sewerage waste should be processed at the site and reused for vegetation.

Beach House Floor Plan

 

There are many designers claiming to have designed good beach house designs, but what a good beach house floor Plan should constitute. I think fundamentally the good beach houses designs should have these considerations:

 

  1. First and fore most Beach House floor plans needs to be designed as a resting abode, after a stressful working time. It should be a place where ones nerves are calmed settled.
  2. Secondly the plans need to be designed for recreational activities such as games by the beach, a BBQ by the patio or terrace etc. The idea of a beach house is also to get together for some fun.
  3. View of the beach from the living, dining and the bed room is essential feature. Create a warm spectacular view of the beach, jetty and surrounding landscape. You may achieve this by having large glass window panels for visibility but carefully shaded for energy savings. Read on smart landscaping on how you can achieve Net Zero Energy building by smart landscaping.

 

Beach house and cottage house

Cottage Beach house, 1*

 

  1. Use a courtyard with landscape within the beach house as it creates a world of the beach within where views are not permissible or even a swimming pool to relax within when it is not comfortable at the beach.

 

 

I love the design of swimming pool in the design of Equis House*2 by Barclay and Crousse. The view of the swimming pool is in the path of the blue ocean. The blue pool is built lifted up in the air that is seen with the blue ocean as the background from the beach house . Where the beaches are scares but merely rock out crops-“a spacious terrace, designed as a man made beach, extends to the horizon line via a unique narrow swimming pool. This area is characterize by its relationship with the sky and the water”*3

 

 

Beach house with a swimming pool

Beach House- Equis House 1*

  1. The beach house shall be a comfortable place- shaded from the heat or cold winds and designed for your specific needs- a sun bathing summer sun or winter views.

 

  1. The floor plan for house need to take the harsh weather beatings- the salt spray in the air would rust down metals and any metal that is not protected well will be rusting away very quickly. So the houses need to be protected well against the weather extremities. And the house needs to be well detailed to serve these purposes.

 

  1. The floor plan for house , should keep the sand out of the foot ware, where it is NOT needed. A good design should to care of this. Sand and dust in the air, can also minimized by a good landscape design to cut of these elements.

 

  1. Don’t forget the context of location. Beach house floor plans need to be designed for the surroundings .If you are in the tropic use the coconut palms as a good element for design. Palm trees make great landscaping for the house. If you are in the Mediterranean Sea use the natural stones, that are richly found in your house design so that it sits comfortably in these settings.
Beach House- house by the sea

Beach House-Play house by the sea

 

 

 

If you are perched on top of a stone outcrop, design for the winds, the great sun sets or sun rise for great vista of the horizons. Remember you can install a wind turbine to harvest wind renewable energy where you can earn money when you are not there. Wind energy harvested well can make your home a Net Zero Energy building, where you can sell your net zero carbon emission as money earner.

 

  1. If you run out of ideas, visit us at http://www.sda-architect.com for some great design. Enjoy your visit. These designs have great visuals for floor plan for house.

 

  1. In modern floor plans for great flexibility the open house plan concept is also an option as it provides spaces for privy and wide open space for children to run around within and to have great indoor functions with wide spaces.
  2. Net Zero Energy Architect

It is pertinent that homes are designed for Net Zero Energy building where there total power consumption is reduce to zero over a period of 1 year. A beach house has plenty of sun and wind these resources will contribute much renewable energy. It is a shear waste of resources in the light of the Net Zero Energy building favored by the Department of Energy in the US (DOE). Ashrae 2020 envisioned that all building tends towards Net Zero energy building by the year 2030.

  1. Should you need advise kindly call our Net Zero Energy Architect in our website at http://www.sda-architect.com
  2. Our Net Zero Energy Architect will attend to your needs as soon as possible to your satisfaction
  3. Lastly have fun in your venture in seeking for Net Zero Energy building plans.

Diagram above is a modification and reinterpretation of Tom Hootman‘s energy savings concepts.

Other Design Process which ought to be integrated in the building design are:

a) create a shoe box model of the tower and analysis the energy consumption, using this model as a basis of comparison for the proposal for the detail design.This will be called the control energy model

b)Add features which will help to reduce the energy consumption as listed above from  Steps 1 to Step 8. Using he control energy model above, the energy saving are evaluated and compared for each of the proposal

c) The Benchmark for energy consumption is established by the Consultant using the Peers Buildings Baselines and the energy pie is created with benchmark for each category of the energy pie.

d) Specific modification are made based on this energy data.

e)The renewable energy normally are a very costly element. it is advise that the options such as Photo Voltaic systems , wind turbines, biomass energy harvesting systems, geothermal heat/cooling systems  from the ground are studied carefully  to make up for the  last remaining portion of the energy pie to create the Net Zero energy building . The last remaining portion reduced to a minium of the total 20-25 % of the total energy pie.

There are 4 Definitions of Net Zero Energy Buildings by the NREL (The National Renewable Energy Laboratory):

  1. Net Zero Site Energy Building -a building that produces as much renewable energy as it uses over the year.
  2. Net Zero Source Energy Building – a building that produces as much renewable energy as it uses over the year when accounted from the energy source.
  3. Net Zero Energy Emission Building -a building the purchases or produces enough emission-free renewable energy to offset the emission from the energy used in the building
  4. Net Zero Energy Cost Building-a building that receive enough financial credit to offset the energy consumption of the building over a period of a year.

The Net Zero Energy Cost Building is preferred definition as it is much easier to achieve and convince the building owners to adopt the proposal of  can see the actual cost benefits for the money  invested in to achieving the Net Zero energy building. In the case of a large development such as a 64 storey office tower, the cost for Green and sustainability would range about USD15million. therefore any vested investor would like to see invested money returned over a period of time. The achieving Net Zero Energy Emission Building are long shots deals as it can be capitalized eventually by selling  Carbon print to companies of vested interest

How to Build a Log House-Part 1

Construction Lesson 1 (Sill Logs, Floor and Joints)

 

What are the Sill Logs?

Sill logs are the logs that rest directly on top of the foundation and its connected to it by the anchor bolts.

 

How to Choose Your Logs?

  • Just about any type of log can be used, as long as it’s relatively straight and it is around 8”-10” diameter.
  • It has only minor tapering no more than 2”. And the length for it is around 16 ft.
  • Conifers such as pine, fir, spruce and tamarack are preferred because these softwoods are workable, durable and relatively lightweight.
  • Hardwoods, particularly oak can also be used, though their sapwood is highly susceptible to infestation by borers and fungus.

 

Sill Logs:

  • After completing the foundation based on the house plan the work on the upper part of the house begins.
  • The first step in the house structure is to install the sill log on the floor plan
  • Note: this is an important part of the job because if the sills are not laid as mentioned in the house floor plan and if its not laid squarely and securely that might effect the whole structure.

 

Steps of Constructing the log house Sill Log.

  • If you don’t want a full basement, you must excavate the house plan dimension at least below the frost line, install footings and construct a wall up to 20 in. above grade level.
  • You must also install piers within the foundation walls as mentioned in the architecture plan to support the floor girder. Also, install anchor bolts along the top of the walls to attach the sill.
  • Begin floor construction by hewing or cutting flat the bottom of the sill logs.
  • Then make holes in the sill logs to fit in the anchor bolts and install sill sealer or a termite shield according to the local building code.
  • The corner joints are made by bottom notching the logs based on the house design.
  • Hew flat the top of the girder and install it over the support piers.
  • Join it to the sill with a mortise and tenon joint. Drive nails through the top of the tenon and into the mortise to complete the joint.

 

Steps of constructing the log house sill log and floor:

  • In a similar manner, hew or cut flat the top of the joists and install them between the girder and sill logs so they are flush with the top of the girder.
  • Install the sub flooring perpendicular to the direction of the joists. Now you’re ready to start on the walls as designed in the architecture plan.

Steps of constructing the log house wall joints:

  • Many different types of notches can be used to join the logs, but a good choice for the beginning log builder is the scribe, fit, round-notch method.
  • It features semicircular notches cut in the bottom of the logs to fit over adjacent logs. Also, a V-shaped groove is cut down the length of each log bottom so the entire length can sit flush on the log below.
  • Although this method is slower than others, the corner joints are self-draining-water running down the outside of the house hits the log tops and runs off, instead of being trapped in the notch.
  • The V-grooves also eliminate air drafts between the logs.
  • The joints between courses do not need chinking, so you can avoid one of the most chronic maintenance problems of log homes: repairing cracked chinking.

Net Energy Building for Office Tower

Models for Net Zero Energy Buildings are used by  Net Zero Architects to calculate the amount of energy saving in the schematic stages of the design, which then are  used as a basis of energy  design control through out the design implementation stages.The model is a 3-D electronic model of a building, it is also a simplified model without much details of the building, which will help calculate the calculation intentions. It is refereed as a shoe box model. There are many types of models used in designing a Net Zero Energy Building design.There are 11 types of Energy Model, which are:

1.) Heat Transfer model for Net Zero Energy Buildings in House Floor Plans
Model show that show how the heat is transferred from the outside to the interiors of the building architectural floor plans.
2.) Lighting model for Net Zero Energy Buildings  in House Floor Plans
Model showing how the day light penetrates top the interiors of the building and it helps Architect to design the light fittings in the building architectural layout outs.
The study of a the lighting levels through out the day would show the amount of light derived from the sun into the building and it helps the Net Zero Energy Buildings Architects to design the additional lighting need ed to make the building sufficiently lighted up.
The amount of light that can be daylight harvested can also be studied, note the amount of light lux derived from the sun is about 100,000-140,000 lux in comparison to what is needed in the office space is only a merger 400lux, the potentials of day light harvesting has to be considered seriously in the light of the current worldwide needs.
3.) BIM Model-Building Information Model for Net Zero Energy Buildings  in House Floor Plans
A digital computerized model, which has information about clashes of the architectural and engineering elements, it provides information about costing, and when plug-in with time project management time line program, we are able to produce the physical model developing over the time line of the builder. The model can be used to study the thermal heat, energy model and total embodied energy of the building architectural plans. This is a great tool for architects and project management consultants.
4.) Energy Model  for Net Zero Energy Buildings  in House Floor Plans
–A simple model used for computerized computation of the energy usage in the building for every month or per year based on the climate conditions, and the building insulation and orientation for buildings. A designing tool, which is helpful to Net Zero Energy Buildings Architects in  choosing the mass proportion and selection of materials.
5.) Wind Model for Net Zero Energy Buildings  in House Floor Plans
– A simple model used for computerized computation of the direction of the wind into the building based on the openings of the buildings. It will help Net Zero Energy Buildings Architects to decide where openings shall be created to enable wind to be harvested.
6.) CFD-for Net Zero Energy Buildings  in House Floor Plans
Computerized Fluid Dynamics is a study of the flow of air in  a  building, where the direction is established and the comfort is designed and it is a tool for Net Zero Energy Buildings Architects to remove impediments to comfort. It helps the architects to design buildings of how the heated air flows, how the ventilation of air flows throughout the building.
7.) Massing and Study Model for Net Zero Energy Buildings  in House Floor Plans
-a model used by Net Zero Energy Buildings Architects to evaluate the proportion, the shape , bulk , form aesthetics and how the form affects the environment.
8.) Thermal Model for Net Zero Energy Buildings  in House Floor Plans
– a model which reveal the sides of the building, where is heated up during the day. With the Thermal model the building designer may be able to decide how the building may be treated or insulated to keep the thermal heat from entering in to the building.
9.) Solar Path Model– for Net Zero Energy Buildings  in House Floor Plans
The path of the sun through out the year, and how it affects the building’s shadow and how it affects the sun’s rays into the window openings and show how the sun’s ray falls on the building and the building’s shadows is cast and how the neighboring building’s shadow affect the building that is being designed.
10.) Ventilation Model– for Net Zero Energy Buildings  in House Floor Plans
The study of wind and movement of air within the building
