A whole-house approach was applied to upgrade the energy efficiency of this once dilapidated property and to install zero energy technologies including photovoltaic roof panels, an active solar hot water system, and geothermal heating and cooling.

The property is set in an area with costly energy prices and a strong state renewable energy program. This combination was perfect for creating a zero-energy remodel that makes economic sense. It is estimated that this remodel decreased the heating and cooling energy consumption by approximately 60 percent.

Energy efficient strategies were derived from and contribute to the Strategies for Energy Efficiency in Remodeling (SEER) project. The SEER project was developed by the NAHB Research Center (NAHBRC) as part of the DOE Existing Buildings Program under the Building America umbrella. The Building America program is sponsored by the Department of Energy (DOE) through the National Renewable Energy Laboratory (NREL).
