ASHRAE and IES Seek to Lighten Energy Use
November 26, 2009

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and The Illuminating Engineering Society of North America (IES) want to “lighten up” your energy use. ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. Currently, 15 proposed addenda to the standard are open for public review.

Among the proposed addenda out for public comment is addendum cd, which would require active exterior control rather than just require the control capability; add bi-level control for general all-night applications, such as parking lots to reduce lighting when not needed; and add control for facade and landscaping lighting not needed after midnight.

The proposed addenda to ASHRAE/IESNA Standard 90.1 are available for comment only during their public review period. To read the addenda or to comment, visit the ASHRAE Public Reviews website.
