The net-zero energy test house at the
The 2,700 square-foot (252-square-meter) test house is built to U.S. Green
Despite 38 days when the test house's solar panels were covered with snow or ice, the Net-Zero Energy Residential Test Facility's (NZERTF) sun-powered generation system produced 13,577 kilowatt hours of energy. That's 491 kilowatt hours more than used by the house and its occupants, a computer-simulated family of two working parents and two children, ages 8 and 14.
In terms of energy consumed per unit of living space-a measure of energy-use intensity-the NIST test house is calculated to be almost 70 percent more efficient than the average house in
In relation to cost, the NZERTF's virtual residents saved
In all, Kneifel estimates that incorporating all of the NZERTF's energy-related technologies and efficiency-enhancing construction improvements would add about
Planned measurement-related research at the NZERTF will yield knowledge and tools to help trim this cost difference. Results also will be helpful in identifying affordable measures that will be most effective in reducing energy consumption. And research will further the development of tests and standards that are reliable benchmarks of energy efficiency and environmental performance overall, providing information useful to builders, home buyers, regulators and others.
