ASHRAE
In excess of 30 percent more energy can be saved using the 2010 version of ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, than the 2004 version, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recently announced.

According to analysis performed by Pacific Northwest National Laboratory (PNNL), without plug loads, site energy savings are 32.6 percent, and energy-cost savings are 30.1 percent. With plug loads, site energy savings are 25.5 percent, and energy-cost savings are 24 percent.

On a nationally aggregated level, building-type energy savings ranged from 8.8 percent to 38.3 percent, and energy-cost savings ranged from 7.9 percent to 33.6 percent, figures that include energy use and cost from plug loads.

PNNL modeled 16 different building prototypes in 17 different climate zones for a total of 272 building-type/climate-zone combinations.
