The updated requirements will ensure that the government’s Energy Star label continues to deliver an increase in energy efficiency over homes that are built to code and standard builder business practices.
These guidelines will go into effect in January 2011, although some builders may choose to adopt the new requirements earlier.
The new guidelines for Energy Star qualified homes include comprehensive air sealing, properly insulated assemblies and high-performance windows to reduce utility bills, and high-efficiency heating and cooling systems engineered to deliver comfort, moisture control and quiet operation, and equipped with fresh-air ventilation to improve air quality.
Because Energy Star homes offer a tightly-sealed and insulated building envelope, a package of flashing, moisture barriers, and heavy-duty membrane details is critical to help keep water from roofs, walls, and foundations for improved durability and indoor air quality.
Energy Star homes should also feature Energy Star qualified lighting, appliances and fans helping to further reduce monthly utility bills.
In addition, Energy Star qualified homes require verification by independent Home Energy Raters who conduct a series of detailed inspections and use specialized diagnostic equipment to test system performance.
