To find cost effective ways to improve the energy efficiency of Habitat homes
To calculate energy profiles of home designs developed by the Floor Plans Team for use in presentation by the Software Team
Create a model of a Habitat house within the Energy 10 software
Simulate the energy use of a home for a year
Make modifications to the base model and compare to current design
Compare energy savings to cost of design changes

Energy 10 Inputs– Floor plan– Air infiltration model– Lighting profiles– Local utility costs– Shading– Insulation– Weather
Base Mode Simulation Results– 92,000 kBtu annual energy use
– $800 annual energy cost
– 60% due to heating
