Energy analysis and monitoring of this home was completed in conjunction with the National Renewable Energy Laboratory’s Exemplary Home Program.

This home was built on what is normally considered a less then perfect site for optimizing solar energy i.e. east-west slope. Careful design and grading provides passive solar gain for both the main living area and for a walk out basement. The home has 2×6 exterior walls with ¾” Styrofoam on the exterior for an R value of 22.75. Radiant barrier is installed on the roof and local eastern cypress is installed for siding.  There is a decorative slab in much of the first floor with a portion that has decorative wood inlaid, or is scored to provide a decorative detail. The house also includes the following: HVAC – 2 stage heat pump – Rinnai on demand unit exterior to the house for better indoor air quality, plus solar hot water heater – 1.5 KW solar electric system with battery back-up
