DOE Tour of Zero: Garbett's Net Zero-Energy Home at Rosecrest by Garbett Homes
You are here
This high-performance home built by Garbett Homes near Salt Lake City, Utah, is a certified U.S. DOE Zero Energy Ready Home.
The 4,111-square-foot production home is expected to save its homeowners more than $3,500 a year in energy costs in a Utah climate that experiences extreme hot and cold conditions.
The Garbett home’s exterior siding is a combination of durable fiber cement, brick, stucco, and cedar siding.
The dry-by-design foundation starts with a properly graded site that encourages water to drain away from the home on all four sides.
The ultra-efficient foundation insulation includes 2 inches of closed-cell rigid foam insulation installed on the exterior of the basement walls.
A 10.29-kW solar electric system more than meets the electric needs of the home, while a solar thermal system reduces domestic hot water energy use.
The sunlight filling the natural daylight home is supplemented by high-efficiency compact fluorescent lighting.
High-efficiency ENERGY STAR-labeled appliances and water-saving low-flow fixtures help reduce energy and water bills.
An ultra-efficient central air source heat pump with high-efficiency gas furnace backup provides heating and cooling delivered by an interior comfort delivery system with ducts installed in dropped ceiling soffits below the attic.
The high-efficiency advanced wall framing uses less lumber, leaving more room in the walls for the blown-in fiberglass insulation.
The high-performance thermal enclosure consists of taped rigid foam exterior sheathing, house wrap, and properly installed window flashing under durable exterior claddings.
