The deadline for the comment and review period for proposed addenda to ASHRAE 90.1 is Sept. 28, 2009. ASHRAE 90.1 is the ANSI standard that serves as the basis for energy codes in the United States. The addendum proposes to reduce Lighting Power Allowances (LPAs) for most types of spaces. For a few types of spaces the lighting power allowances will increase. The proposed addendum also allows LPAs to be increased for spaces where a Room Cavity Ratio threshold is exceeded, or for spaces with permanent obstructions.
