Last year, the Environmental Protection Agency (EPA) completed the rollout of version 3 of its Energy Star for New Homes program, and more HVAC contractors became involved in this process to certify efficient homes.
Homes built to voluntary Energy Star specifications made up about 26 percent of all new homes constructed in the U.S. in 2011. Under the latest update of the specifications, Energy Star homes consume at least 15 percent less energy than those built to the 2009 International Energy Conservation Code (IECC).
The Air Conditioning Contractors of America (ACCA) announced that it has recognized its 500th Quality Assured (QA) contractor. ACCA launched the QA program in February 2011. Since then the association said there has been a steady flow of contractors applying to the program.
