DOE Tour of Zero: Flagstaff Meadows Model Home by Capstone Homes
You are here
Capstone Homes built this 1,941-square-foot affordable home in Bellemont, Arizona, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
This cost-effective home was built in Flagstaff Meadows, which is Flagstaff's first Zero Energy Ready single family home community.
The builder specified that the home’s dual-pane, low-E, U=0.34, vinyl-framed windows were a model compatible with the home’s high altitude setting.
ENERGY STAR-certified appliances including the refrigerator and the dishwasher add to energy savings.
The Internet-connected home security and energy management system includes leak sensors in the bathrooms and kitchen that will alert homeowners if there are leaks in the faucets or under the sink.
All of the home’s lighting is LED, with two interior motion sensors and two interactive light switches.
Two inches (R-10) of rigid foam lined the interior of the perimeter footing walls before the post-tensioned slab was poured.
The home’s 2-by-6 walls are filled with R-22 of open-cell spray foam, which insulates and air-seals the exterior walls.
The attic is insulated along the underside of the roof deck with 8 inches of the roof.
A natural gas 94% efficiency tankless hot water heater provides endless hot water.
Capstone cut air leakage by more than 67% with an aeroseal whole-house air-sealing process that consists of spraying a nontoxic sealant into the air while the home is pressurized with a blower door kit that carries the sealant particles to any holes in the building envelope.
