Revisions to ASHRAE Standard 90.1 Would Expand Scope

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has proposed six addenda to Standard 90.1-2007 that would expand its scope and change how lighting efficiencies are calculated.

One addendum would add operations and maintenance as well as renewable energy to the scope of the standard, which currently covers only the design and construction of buildings. Other addenda would add calculations for exterior lighting power limits and would expand the applicability of lighting-efficiency standards.

The addenda were released for public comment late in 2008, and, if passed, would become effective sometime in 2009. More information is available at
