 Geothermal heat pump  Solar radiant floor heating  Geothermal heat pump provides cooling as well as heating.

 Large south-facing solar panel on the roof,  Passive Solar

 The most important aspects of our design would have to be the size of the house and the alternative energy sources used to generate electricity.  Having a smaller square footage allows our ZEH to use less energy to provide heating and cooling throughout the house.  Having alternative energy sources such as solar panels, allows us to be less reliant on electric companies.  The house forces a lifestyle change by switching to a natural food source.

 “My favorite feature was the rooftop deck area where you can set up a grill and chairs and cook food and relax.” -Tyler  “My favorite aspect is the rooftop garden to provide natural, organically grown food, while also absorbing heat that would be transferred to the home during the summer.” –Brandon  “My favorite feature is the radiant floor heating because it gives the house a unique functionality and in the winter makes waling around the house in socks unnecessary.” -Ben  “My favorite feature is the log walls because it gives the house a pleasing aesthetic look, and functionality as it keeps the house rather air tight.” - Andreina

 Importance of passive solar heating  Gained skill using SketchUp program  Useful for future planning  Learned about how zero energy homes ration out their energy throughout the year.  Produce enough energy in summer to offset energy cost in winter.
