1. SPRING 2010 Spring 2010 CS 8803 - Happy Healthy Home Zero Energy Homes By ANUJA CHOCKALINGAM SURABHI SATAMHappy Healthy Home

2. SPRING 2010 Spring 2010 Contents Project Idea Survey – What really matters to people? Analysis Conclusions

3. SPRING 2010 Spring 2010 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’.

4. SPRING 2010 Spring 2010 What is Zero Energy Home?

5. 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 What is Zero Energy Home?

6. SPRING 2010 Spring 2010 SURVEY WHAT REALLY MATTERS TO THE PEOPLE?

7. 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? SURVEY - WHAT REALLY MATTERS TO THE PEOPLE? RESPONSES

8. SPRING 2010 Spring 2010 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.

9. SPRING 2010 Spring 2010 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.

10. SPRING 2010 Spring 2010 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.

11. SPRING 2010 Spring 2010 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).
