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.

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

Contact us for your NZEB designs..we will be able to help you in the interest to secure the building in being less independent to the energy utility companies.check out our house floor plans.
