ASHRAE/IES 90.1-2013 Gains 30% Savings over 2004 Standard
The requirements of the 2013 revision of ANSI/ASHRAE/IES Standard 90.1-2013 will result in buildings that could achieve six to eight percent more efficiency than buildings built to the 2010 standard.
Published in October 2013, the 90.1-2013 Energy Standard for Buildings Except Low-Rise Residential Buildings, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. Pacific Northwest National Laboratories (PNNL), in support of the Department of Energy’s Building Energy Codes Program, conducted the energy savings analysis on 110 addenda included in the standard.
PNNL’s analysis shows that the site and energy cost savings are 37.7 percent and 37.8 percent, respectively, by using the 2004 standard as baseline for the regulated loads only. For the whole building energy consumptions, national aggregated site energy savings are 29.5 percent and energy cost savings are 29.0 percent.
On a nationally aggregated level, building-type energy savings range from 19.3 percent to 51.9 percent and energy-cost savings from 18.6 to 50.6 percent. These figures include energy use and cost from the whole building energy consumptions including plug and process loads.
