Project Idea Mainly revolves around people’s idea of an Eco friendly Homes

• Eco-Friendly: having little or no impact on the Native Eco System.

• Reduce the environmental impact on the planet.

• Demonstrates how ‘Less means more Quality Living’.

What is Zero Energy Home?

SPRING 2010

Spring 2010

Definition: It combines state-of-the-art, energy efficient construction techniques and equipment with renewable energy systems to return as much energy as it takes on an annual basis.

Goal:• Reduce carbon footprint• Increase energy efficiency

SURVEY

WHAT REALLY MATTERS TO THE PEOPLE?

SPRING 2010

Spring 2010

-Which energy improvements make sense for my situation?

-What is the real payback of each improvement?-Does renewable energy make financial sense given the

other improvements possible?-What is the best heating and cooling system for my

situation and preferences?-What is the ‘right size’ for my system ?-Will all the rooms be the same temperature?-What are my options for healthy indoor air quality?

Analysis

• Everyone’s main concern is Cost, easy Temperature control and Quality.

• People have a clear understanding of Zero net energy homes that ZEH are homes which are often equipped with solar power and are designed to generate more energy than they consume.

Conclusion

Renewable Energy: Approach your project from a true whole building perspective and provide a comprehensive strategy for the following:– Building envelope– Heating– Cooling– Hot water– Appliances– Lighting– Ventilation– Energy production etc.

Conclusion

Right Sized Equipment Reduces Costs and Increases Performance:

• Improper HVAC sizing and layout can lead to humidity and mold problems, system inefficiency, and short cycling with mechanical failure and shorter system lifespan.

• The right-size and design the systems to avoid these problems, ensure the best performance, and reduce costs associated with installing a bigger system than is needed.

Conclusion

Sustainable Options: • Alternative choices that can either reduce or

eliminate fossil fuel use completely on your site.

• Potential targets can be to reduce or offset your carbon footprint, create a fossil fuel free site, or incorporate renewable energy systems to partially or completely off-set annual energy consumption (zero net energy).
