This presentation summarizes the modeling and simulation of a net zero energy building (NZEB). It discusses how buildings account for a significant portion of carbon emissions and how NZEBs can help reduce this impact. It also outlines the key design elements, benefits, and modeling process of NZEBs. The presentation shows the 3D modeling and energy usage simulation of a sample NZEB in Revit and finds it uses less annual energy than a conventional home while providing benefits such as lower costs and reduced carbon emissions.

3. LITERATURE REVIEW
• Buildings are responsible for approximately one-third of worldwide carbon emissions
• Currently, small scaled developers and investors are started to attempt and
understand how to reduce energy and CO2 in their buildings but there is a lack of
potential technologies and policies to help them understand if they are on track to
achieving such goals.
• The term Net Zero Energy Building "NZEB" is now widely used commercially in the
building and construction sector but without a clear definition and understanding.
• To understand more about NZEB, research on the same has been done.

4. Introduction
• Construction industries can play a
significant role in driving the majority of
energy use.
• Building sector accounts for between 33-45%
percent of the world's carbon emissions.
• Energy efficiency investments can be a
profitable strategy to reduce carbon
emissions [1].

5. • It was crucial to focus on lowering the amount of
energy used in these structures by utilizing cutting-
edge concepts and technology.
• A promising plan for reducing the environmental
impact of buildings is the development of Net Zero
Energy building.
• In comparison to a comparable ordinary conventional
building, a Net Zero Energy (NZE) building is much
more fruitful.

6. • In NZEB, a yearly amount of local renewable energy generation is equivalent
to their load demand.
• A Net Zero Energy building can be made possible by architectural features that
provide high levels of energy efficiency and renewable energy production [2].
• These structures are required in order to synchronize the power grid,
import power when it is needed from it, and export surplus power back to it.
• .It is obvious that a zero-energy building requires a significant investment
budget and high capital expenses, but both will pay off for the owners within
a set number of years [3].

8. Design Elements for NZEB
• Passive building design – to reduce energy load.
• Active service equipment and facilities - to maintain the interior atmosphere and
resident comfort.
• Systems for generating renewable energy – to obtain renewable energy [4].

10. BENEFITS OF NZEB
• There will be a reduction in the annual cost of living.
• Renewable resources are more dependable and have longer lives.
• The owners of the buildings will not be affected by any energy austerity in the
electrical energy during peak loads or load shedding.
• The prices of the zero energy buildings still have high potential when it comes to re-
sales.
• The carbon dioxide emissions could be drastically reduced in the future [5][6].

11. MODELLING AND SIMULATION
• To create a building design that takes into account all of these
elements, we need software that enables us to assess the
electrical power requirements.
• Revit is a BIM (Building information modeling) which help
architecture, engineering teams to design infrastructure
and building with greater accuracy and simplify complex
problems.
• Users can create a building or structure and all of its
parts in 3D and add 2D drafting elements to the model.

15. Average daily energy use for conventional home 46.565kW
Average year-long (annual) energy use for
conventional house
16996.225kW
Average daily energy use for NZE house 30.193kW
Average year-long (annual) energy use for NZE
house
11020.445kW
Difference in the energy consumption 16996.225kW - 11020.445kW =
5975.78kW

16. RESULT AND DISCUSSION
• NZEBs have a variety of benefits, many of which are described earlier, despite their
initial expensive cost.
• Government authorities can handle energy crises and environmental changes
by offering incentives and subsidies to investors.
• Energy costs will be very low or almost nonexistent, and selling extra energy will
result in a profit.

17. CONCLUSION
We can conclude that the NZE Building is better than the conventional buildings in
various ways as mentioned.
