Five Models of Energy Efficiency: A Guide to Beautiful, Energy-Efficient Homes
Five US builders are being honored for their exceptional achievements in high performance building at the second annual BASF Builders Challenge Awards.
Led by the U.S Department of Energy (DOE), the Builders Challenge is working with homebuilders across America to build a new generation of high-performance homes, working toward the ultimate goal of providing cost-effective, net-zero energy homes by 2030 for all Americans.
To qualify for the Builders Challenge, homes must meet at least a 70 on the EnergySmart Home Scale (E-Scale) — which means they must use at least 30 percent less energy than a typical new home built to code.
2010 BUILDERS CHALLENGE AWARDEES
Colorado Builder’s Net-Zero-Energy House Costs Just 7% to 8% More
Ecofutures Building Inc. developed four certified Builders Challenge homes (two with minus-three HERS ratings). These net-zero-energy measures represented only 7% to 8% of the total building cost.
Artistic Homes of Albuquerque offers a net-zero-energy upgrade option on all their homes. They’ve completed and sold 11 true net-zero-energy homes ranging from 1,305 to 2,905 square feet and costing between $160,000 and $300,000.
Tim O’Brien, a fanatic about eliminating air infiltration, actually got $400 back from the utility the first month after construction was finished. He guarantees a zero energy cost for the first 5 years on his home.
