Features
Buildings are designed for 100% solar space heat and domestic hot water. No boiler or conventional water heater is required. Solar heating incorporates energy storage to maintain comfort for ten consecutive cloudy days. A small wood stove, producing 25,000 btu/hr, and fired for only 8 hours per day, can extend this to 30 sunless days. Really.
Photovoltaic (solar) electric panels provide 100%+ of annual electricity use. Optional battery or generator back-up can accommodate “off-the-grid” installations.
This energy performance is achieved through site-specific adjustment of design parameters that include:
Detailed calculations reflect the anticipated occupant’s need for domestic hot water and the important meteorological variables of the location. These include:
Systems design and component selection are based on thoughtful energy flow management and energy efficiency, taking care to make use of the stream of waste energy where possible, and to maximize the use of natural phenomena including sunshine, shade, diurnal temperature variations, wind, rain, humidity differential, etc. Each item incorporated into the construction is evaluated carefully for its contribution to the overall energy efficiency of the house as a whole. Each item is also selected with serious consideration of the environmental impact of its manufacture, delivery, and ultimate disposal.
