Green Building and Long-Term Sustainability

Keller Court Commons is built recognizing the built environment has profound effects, both positive and negative, on the natural environment, as well as the people who inhabit the homes.  The greatest environmental impact from homes is size – the volume of materials and energy extracted, processed, transported, and maintained during the life of a home.  The homes are mid-size, 1,400 to 1,500 SF – the average size of homes not long ago.

To reduce the use of non-renewable energy all homes have a 2.8KW solar electric system as well as state of the art high-efficiency hybrid heat water heater for both domestic water and radiant floor heat.  Interior materials have been selected for good interior air quality.  The homes are very well insulated – blown-in-batt walls and ceilings with a combination of closed cell foam and batts.  The home exteriors are constructed with long-term, low-maintenance materials such as Galvalume siding and roofing, metal windows as well as solid cedar siding.
