Painted Hills house net-zero SIP project

The Painted Hills house is a solar-powered employee home at the John Day Fossil Beds National Monument and is the first net-zero home in the National Park Service. It was designed and built with the goal to generate as much or more energy than it uses. SIPs (structural insulated panels) were selected in the design to offer superior insulation and reduced infiltration to provide the most efficient building envelope.

The house also generates energy through photovoltaic solar panel system, solar hot water heater, and produces enough energy to not only cover the residents use but also to charge the occupant’s electric vehicle.

The R-Control SIP panels were manufactured by Big Sky Insulations of Belgrade, Montana.  The designer was Zero-Energy Plans, LLC and the builder was Kirby Nagelhout Construction Company.
