Architect: Michelle Penn, AIA This barn home is modeled after an existing Nebraska barn in Lancaster County. Heating is by passive solar design, supplemented by a geothermal radiant floor system. Cooling uses a whole house fan and a passive air flow system. The passive system is created with the cupola, windows, transoms and passive venting for cooling, rather than a forced air system. Because fresh water is not available from a well nor county water, water will be provided by rainwater harvesting. The water will be collected from a gutter system, go into a series of nine holding tanks and then go through a water filtration system to provide drinking water for the home. A greywater system will then recycle water from the sinks and showers to be reused in the toilets. Low-flow fixtures will be used throughout the home to conserve water. Photo Credits: Jackson Studios
