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 This pledge, originally made at the United Nations Climate Change Conference (UNFCC) 2009 in Copenhagen, Denmark, was conditional to receiving technological and financial assistance from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.

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.

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.

 The houses are traditionally timber house plans. Some of oldest houses dated from the 16th Century. These houses are now in museums which is an object of study by craftsman and builders.

The plan of the house and how it is used also remain traditional. Only the kitchen and sometimes the place for eating meals are modern; the other rooms, for working, sleeping and social intercourse, remain true to tradition. The floor is covered with straw mats (tatami); the family kneels at low tables to eat and drink, and they sleep on the floor as from time immemorial. <4>

Thus living in the Japanese style broadly implies adherence to tradition, just as we would do if we dwelt in modified chalets in our central European cities. The architect, as a ‘creative’ designer, has no part to play in the traditional housing of Japan. The craftsman designs the house according to ancient traditional rules, as was the case for centuries in our mountain valleys.

The Design of The Traditional Japanese House
The Traditional Japanese House has view into the garden, the house is flexible , the strength  of the house and the beauty of the house is amazingly well built all together that creates a wonderful and comfortable ambiance as one enters into the The Traditional Japanese House. The comfortable feeling is what Architects try to create, a feeling that put you to ease as you are inside the home.

 a)Views into the garden

The houses are design for views in to the garden, balconies are surrounded with cuts the sun and the harsh weather in the homes. Balconies are essentially a major feature of the Japanese House.

b) Flexibility

The partition made of light material to allow flexibility of the use of room. A living room could be the dining, or even a common family area. Sliding Shoji Screens are common.

 c)Strength of structured

The structure of the timber that is used of extra strength to endure the weathering and the earthquakes that Japan is so frequently subjected too. While the structure is robust the internal materials are light weight using paper, bamboo, straw and timber.

d)Beauty

The elegance and grace of the house is aesthetically designed to bring a simplistic view of the house with little furniture which helps the mind to likewise be simple and functional in thinking and living.This helps to think straight and live straight disciplining the mind and the body.

The Japanese House Plans
As you enter into the house, the shoes are removed at the Genkan( Hall way) and slippers are worn .

 Architectural Insights
Economy and brief of material used is maintained and the use of light passing into spaces via translucent material is common.

The perfect proportions of squares are used relating to the tatami mats.

Haiku timber House
Haiku is a type of poetry, which means each poem contains seventeen syllables–frequently in the order of 5, 7, 5 syllables .The theme of haiku poetry is the relationship and interaction between nature and humankind.Haiku says that form and function are one. This philosophy was adopted by Frank Lloyd Wright. Haiku Houses have many of the features of their Bungalows.It is elegant and beautiful, priceless in its inherent peace, tranquility and harmony.

The Traditional Japanese House were in many way designed for Net Zero Energy Building, firstly  the house were made of timber which was a naturally abundant and the veranda  were thermal zones which kept the heat away during the summers the smart landscaping  kept the heat  away during summer and the homes were lifted above the ground to keep the heat away from the ground which air below the floor was a good form of insulation, the interiors were made of paper which was an excellent material which insulated the interiors form gaining heat nor losing heat during winters, with respect to Green sustainability the choice of timber could never get better.

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).

 

renewable energy

wind turbine

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

key words: Project Architects,Resident Architects,Design Architects,Bungalow Architects,Shopping center specialist Architects,Interior designing,Hotels Architects Architects,Hospital Architects, Architect Arbitrator ,Commercial Office Architects,Architect Planners,Landscape Architects,Timber building Architects,Resident Architects. arkitek

There are many Types of Architects  listed below are some of them and what they do:
Many types of Architects are covered in these website such as Green Architect,Net Zero Energy Architect, Eco Green Architect.

Principal Architect

He is runs the Architectural company, he may be the founder, owner of the company

Project Architects

What does a Project Architects do?
The Project Architect  manages a team of Architectural office staff consisting of Resident Architects , Design Architects and a team of draftsman .He ensure the project is managed contractually ( contract administration. A Project Architect is  used for a large project  or he would be required to deal with many smaller projects.

He reports firstky to the Pricipal Architect of the comapny and he may report to the Owners of the building ( or a Project Management Team). He rports on the overall progress of works,manages changes that occurs which may arise from time to time ,manages the Program or any issues that may arrise at the site. He also manages a consultant teams of Civil & Structural Engineers, Mechanical and Electrical Engineers, Urban Town Planner, the Cost consultants( called the QS), and Landscape Architect, Interior Designers, Specialist Consultants such as –Acoustic consultants, Lighting consultants, Façade consultants and Green Sustainability, Net Zero Energy Consultants and Ecologist. The contractor or the builder reports to him on the progress regularly

Design Architects

What does a Design Architects do?
A Design Architect designs the building, by complying with the client’s design brief and local building code and  bye law requirements. He report to the Project Architect or to the Pricipal Architect. 

He submits the plans to the local authorities for approval and coordinating the approvals of the engineer’s plans to the local authorities as well. The design architect during the construction will ensure the design aspects of the building are attained and reviews the approvals of materials submitted by the Contractor and ensure it is compliant with the specifications of the contract.

Bungalow Architects

What does a Bungalow Architects do?
An Architect that specializes in designing of Bungalows as the design and construction of Bungalow is a rather confine to a very specialized area of work. The difficulty of putting up a Bungalow cannot be underestimated. He  meets the needs of the owner of homes both at a macro level and at a micro level of details. Every nook and corner of the bungalow is subjected to review by the house owner . This Architect ought to be rather knowledgeable about the details of material, construction and aesthetics of the buildings. He should be familiar with the different types of house plans,history of house architecture, the types of houses, large homes and small homes, timber materials , log houses, cottage houses, beach houses, 2 bed room houses, 3 bed room houses, duplex houses, southern living homes, Asian homes and Green Homes, modern house plans, Open house floor plans, Japanese house floor plans etc, It is varied form place to place and region to region. He  designs homes according to the need of the owner and it meeting with the local market value systems to maintain value of the homes.

Shopping CenterSpecialist Architects

What does a Shopping center specialist Architects do?
The shopping specialist architect , deasl with large shopping centers, hyper markets and supermarket. It might seem like a simple thing , which is not true otherwise; in fact a mistake  undertaken in the design of a shopping centers, may result in a gargantuan tragedy. It may resulting in a white elephant or a ghost shopping center. Therefore in selecting an Architect to design a shopping center one should evaluate his background of experiences in shopping centers designs. The strategies to capture the flow of traffic, direct the flow,captivating their interest,lighting levels and the latest trends in shopping is rather important for the success of the shopping center and creating a thriving shopping center.
The Architect will study the types of shops and how it will be laid out to create demand and reduce dead ends of circulation of traffic and is aware of the magic of working public traffic using anchor tenants.

Interior designing Architects

What does, a Interior designing Architects do?
An architect who is specialized in the interiors of the building and creates and transforms the interior spaces to a functional space or a space of beauty. The interior design should begin at the outset of design process making the spaces as an integral part of the building and not as a make over of the design as an after thought. There is a difference between an Interior designer and a interior decorator. A Interior decorator merely provides the make up of the building .

Hospital Architects

What does, a Hospital Architects do?
A Hospital architect deals with an area of specialization  with the internal planning of hospitals. These are medical and health requirements, which shall be complied. All aspects of the spaces are designed with the health of the patients in mind .For instances the lifts are specially  much slower that the conventional lifts it takes into consideration of patients with weak heart or high blood pressure who are susceptible to heart attacks. The rooms are designed for clean room conditions and the air will be designed for clean air to minimize the spread of air borne diseases.Room are subjected to view for quick recover.Planning of the services are necessary for Energy efficiency as Hospitals guzzles energy.

Hotel Architects

What does a Hotels Architects do?
Hotel Architects are specialist in designing the bed rooms, the commercial kitchen, ballrooms, restaurants, lounges, connectivity of service corridors to service lifts, loading, unloading area and the maintenance areas. There are many types of hotels. Some hotels that are  centered around golfing circuits, some are based on beaches fronts, some on ball rooms and seminars services and others dependent on visitors from the Air port or local retail centers etc .Operators of Hotels, such as Hilton  have their own manuals for designing hotels in keeping with their brands.Architect  design according Hotels Operator’s  guidelines stipulated in Operator’s manuals. This will  ensure the operations are efficient and profitable. All 5-6 star hotels will be designed with the Operators requirements at the outset. This will avoid design tragedies and mega failures in Hotels. If you need to know if Design matters, look around at Hotels that have failed in business other than  that “location matters”.

Commercial Office Architects

What does a Commercial Office Architects do?
The design of high rise office towers shall be designed with low maintenance free designs, efficient layout floor plans, high energy performance building, shaded well from the heating sun and conservation of heat during summer and cautiously with the safety of the end users during maintenance of building, design for easy management of the building. New concepts such as Net Zero Energy Building, which is our area of special focus.  Green and Sustainability concepts are introduced by certification bodies such as Living Challenge, LEEDS, Green Building Index,Green Marks etc.

Architect Arbitrator

What does a Architect Arbitrator do?
An architect that is familiar with the contractual relationship between the parties in the building industry and how the function and further more he is most familiar with the designing and the design process and the work that all parties are bound in the industry. And this makes him as a suitable candidate to arbiter the arguments that arise among the parties in the industry. In some countries where there is no Construction court, many lawyers and even Judges are not familiar with the terms of the contract, duties of the parties of the contract and the relationship between them and make the proceeding and the judgments to be miscarried. Therefore it is best to have architects who are legal based who are the best arbiter to conduct and make the best judgment in arbitration case.

Architect Planners

What does a Architect Planners do?
An Architect who is trained academically as an Architect and  as an Urban Town Planner.An architect is aware of what is happening within a building . Town Planner designs a collection of buildings in a Town or country settings. An Urban Planner designs the interrelationships between the buildings. He interconnects the buildings with open spaces, parks and garden etc. Building are designed by architect without any consideration to the buildings in the neighborhoods. It is said that building have to talk to each other and the design of park in relationship with the footpaths leading to one another is necessary to create an wonderful urban environment. Urban Town Planning fills in  these gaps and is a go in between Planning and Architects in urban areas.

Landscape Architects

What do Landscape Architects do?
A landscape architect, at a micro level, is one who designs the soft landscape (plants, lawns, shrubs etc) and the landscape (pavements, benches, footpaths, street lights bollard etc) .
At a macro level he may be a designer as a Town Planner. He may also design the country sides and be involved as Town and Country Planner does in Town and Country Planning.

Timber Building Architects

What does a Timber building Architects do?
An architect who is familiar with the architecture of  timber, the different type of timbers ,how to preserve timber, the art and crafting and beauty of timber . He has an appreciation of the fine timber quality, how to design rustically in some situation ,making a beauty out of the ruggedness of the house.He is a master of timber homes.

Resident Architects

What does a Resident Architects do?
Resident Architects are those who oversea the quality of materials used and overseas the workmanship,during the construction of the building. He will ensure where  standing supervision is required especially where concrete works are carried out.He is partly responsible for the works carried out by the contractor. He ensures the contractor uses materials , specified by the designer (Architects), He is engaged only during the construct of the works until the building is successfully handed over to the Owner of the building. The Owners of the building, may extend his engagement as A Residential Architect until the Building is certified fit for occupation (in some regions this is called the Certificate of Fitness in others it is called Certificate of Completion and Compliance.)
a) He should be able to study all drawings such as Architectural and Engineering . He identifies errors in drawings and missing details .He checks and conduct test on the material that is used by the contractor.There are times although the approved samples submitted are never used on the building during the construction by the contractor. The materials are short changed during the construction . This leaving the building with a massive maintenance problem ,during the life span of the building.
b) He may send the materials to the laboratory for testing to ensure compliance with the specifications.
c) He submits progress report to the building owner and the Principal Architect of the project. He reports the works is in progress and the no of workers at the site. He also report  the equipment used at the site.He reporst the weather conditions at the site.
d) He monitors the Health and Safety Manuals and enforces it at the site such as ensure the use of  Hard Hats, Safety boots, Safe erection of scaffolding , Safety cables, safety nets , safety platforms are in place, ensure no water-ponds are found at site to minimize the breeding of mosquitoes, healthy the living quarters for workers, the Electricity cables are elevated above the ground with proper switch outlets etc.
e) The Resident Architect endorses the correctness of the Contractor’s Progress report.

What is Architecture ?

The question -What is Architecture ? is often discussed among students of Architecture endlessly. Students of Architecture spend a no of years trying to get the grips of the meaning of Architecture. In the early years the students of Architecture are confused trying to get a grips of it. In this article I wish to reduce this gap of bewildering students.

Architecture  is designing the building space in which we live in. Some define it too broadly as “Architecture is “, others define it as “Architecture is Frozen music “. While there is  truth in this definitions, the space we live in and work in , are our Architectural spaces and as such, it is every thing about us- the Environment.

Net Zero Energy buildings

Traditional Malay House,

Architectural design is putting and making a composition of  the space in a logical meaningful way that makes sense. Thereby there is a indirect correlation ship with how music notes are composed. whereas in building the notes are features and elements borrowed from the past or created anew fulfilling a functional need. You can design spaces that are awful and it is poor taste. Good designs have the following intrinsic attributes:

  • Comfortable and Functional
  • Durable with time
  • Sustainable design with eco biodiversity green ecoconsiderations
  • High energy efficient buildings- read-NZEB
  • Creates an ambiance of the space that it was meant to be
  • A space that creates an emotional experience that leaves traces of memorable experience otherwise it is a shell.
  • Reasonable Costed and not flagrant, buildings of exorbitant cost can achieve anything that you want. A insensibly costly building is a sin.
  • Beautiful with the visually, makes the hears hears sound that are pleasing, allow light to flow and thereby making the space an memorable experience.
  • Defect Free, buildings may look wonderful in the beginning but may result in leakage, cracks and uninhabitable conditions is not good architecture, the right material not the right construction is not used.

If any of those above is not found in your Architectural designs, it may be due to a deliberate omission. As to achieve all may be difficult and some times impossible. For instance the most beautiful building with great interiors has terrible structural design and high unreasonable cost. So good Architectural design -is all about making compromises along the way with cost, comforts, durability and other contending elements.

History of Architecture

Architecture is as old as History .When we talk of history of the past civilization, we talk of the architecture of the buildings. And buildings are the only remnants of the past. most record, evidences of the cultural activity is studied by the functional spaces of the buildings.the spaces such as baptismal fonts, altars of worship, temples of ancients, places of sacrifice, inscriptions of words on temple walls. Buildings of the past are mostly temples or buildings of worships. the remnants of homes are generally destroyed except for the remnants of the foundations such as in the Indus Civilizations. The civilizations of the past are :

  • Egyptian, Indian, Chinese
  •  Assyrian Period (before Babylon)*1
  • Mesopotamia (Babylon and Before), Ancient Americas (Mayan       …etc)
  • Persian Period
  • Greek Period
  • Roman Period*1
  • French(Gothic )*1
  • Georgian Architecture-The George Whyte’s House *2
  • England(Georgian, Tudor, Victorian)
  • Industrial
  • Modern
    Today buildings are high influenced by one another. For instance:
  1. the White House was patterned after the grandeur of the Roman Capitol
  2. The high rise buildings, in our cities are influenced by the new material manufactured during these periods after.
  3. The Gothic building followed after the Roman, whereas the Gothic (French) improvised from the Roman Arches and post & beam system to heavy arches(flying buttress) which supported higher and magnificent cathedrals.
  4. Chinese, Japanese Architecture while were developed independently but were not influence by the others neither influenced the world as we know of today. Except the Indian influenced spread to Angkor Watt, Malaysia, and Bali Indonesia, which is now the Bali architecture.
  • Post Modern Era
  • Green Sustainability and Net Zero Energy Buildings Movement

How to use House Architecture in designing your dream home plan

 

An Architect is one who designs your house but an Architect unless he has a great burning passion about his work , then and only then can he realize the dream house plan into a dream home plan. This creation of a home unless worked with love .A house architecture are the principles an Architect to create a dream home .The house architecture constitutes of the following aspects of architectural styles.

 

 Architectural Styles

The architectural house style adopted today have a story to tell of the historical trends of the past. Some of our homes are influenced by the styles of the past movements and revivals of past architectural movements. The classical movement, Gothic, Neo-Classical, Gothic revival movement, Victorian, Tudor etc. and then the Modern, Post Modern and descontructivsm to today Green and Sustainable movement and the Net Zero Energy movement.

If you take time to look of the styles of the homes, you could see how the present home has the tell tales of the architectural movements of the past. The pediments, elements of the building which continues=d to be used even today, is a reflections of these past movements. The White House was built during the times when the Classical revival was current world over.Even as of today some of these features of the White House are copied into our bungalows .

Therefore houses today is telling of  the evolution of styles and end result of technological changes that has brought changes in our society -that is the development of new material and of construction have had a tremendous effect on the styles and design of our dream home plan today. The technogical invention of glass , iron technology and siicone technology has vastly infuenced the kind of office buildings of today.


The architectural house styles available for selection are :

  1. Colonial styles
  2. Classical styles
  3. Spanish styles
  4. Mediterranean styles
  5. French styles
  6. Ranch styles
  7. cottage styles
  8. Log homes styles
  9. Georgians styles
  10. Victorian styles
  11. Tudor styles
  12. Post-modern styles
  13. Modern styles
  14. organic styles
  15. Green architecture and sustainable building style
  16. Net Zero Energy building type
  • In choosing a style, for your dream home plan, you may want to choose from the past as they were and modernize the architectural layouts. you may need to suite architectural layout based on the availability of material locally and type of skilled craftsman. In some regions timber crafts men are available and in others mason workers are found in abundance and thereby you need to adapt accordingly otherwise the cost of the home will not within the affordable cost range.
  • Any attempt to recreate the buildings of the past to its exactness, may be  cost prohibitive. For instances the windows of building of the past are highly ornamented but present day houses are simplified to a great degree.
  • An interesting point is with regards to homes recreating homes of the past to make your dream home plan. has its problems with changes that have happened since such as– The houses of the Founding Fathers in the America had water-wells outside the home. The slaves  fetched water from the well for them to take cold showers.*1 This was so due to the situation of the times. Modifying the homes to suite for the modern day will requires the skills of an Bungalow Architect, do contact us if you need help with this regards at http://www.sda-architect.com

What the basic Net Zero Energy Building Terms used in Design

Net Zero Green and sustainability

Photo Voltaic Panels

The main Net Zero Energy Building Terms  used in Designs are :


1,) Net Zero Energy Building Energy Models
are virtual e models of the building which is based on building physics and it uses a baseline model and compares the energy savings with the proposed model. Interpreting the results will make the difference. Read the 10 types of energy saving model in this blog

The Energy performances are to be controlled through-out the delivery process tracking for net zero energy performance?The entire design team should interface with the energy model for energy modeling to be successfully achieved as an end to the energy model.

Inputs such as OTTV, RTTV, air con loads, temperature set points , outside ambient temperatures, and details about systems will help the energy model to be accurate.A white box model/shoe box model helps to analyze the daylight and energy performances.  A white box model is a simple 3 d electronic model of a building without much details of the building.merely showing the overall shape of the building, and the insulation material will be shown.

These Net Zero Energy Building Energy Models can be created by Sketch up plug in such as  IES Virtual Environment and Energy Plus and Open Studio.This  model study is possible with VE( mass, window/wall ratios).In the future, the Thermal comfort models may be designed for designing purposes.Other Tools box that can be useful are–Weather Maker, sketch up, eQuest, IES Virtual Environment(VE), TRNSYS and THERM

The basic  Net Zero Energy Building Terms used in Designs


2.) Energy-energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.
The types of Energy are – Kinetic Energy, Potential Energy, Mechanical Energy,Gravitational Energy, Nuclear Energy, Chemical Energy, Electricity Energy, Motion Energy, Thermal Energy, Radiant Energy and  Sound Energy.

3.) Law of Thermodynamics states that:
a)Energy cannot be created or destroyed, the sum energy of the universe is constant.
b)Law of Entropy, that energy flow from hot to cold

4.) Power is the rate of doing work or transfer of energy, P=W/t, SI for power is Joules per sec(Watt), a LED using 1watt diode uses 1-watt energy for 1hour

5.) Horse Power is to measure mechanical power,

6.) Btu is heat used to raise the temperature by 1 pound of water by 1 degree F.MBtu is the power to cool and heat water for air con.
Megawatt hour is electrical energy

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
