Using the latest lighting technology and techniques to reduce energy use is proposed in an addendum to ASHRAE’s energy conservation standard. The lighting power limits allowed under ANSI/ASHRAE/IESNA Standard 90.1-2001, Energy Standard for Buildings Except Low-Rise Residential Buildings, would be completely revised under proposed addendum g, recently approved for public review.
Also approved for review was addendum i. The public review dates will be announced later this fall. Addendum g proposes to completely revise the lighting requirements based on the latest technology and techniques. The revisions incorporate recent research on fluorescent fixture light loss factors and space type characteristics of new commercial construction, as well as revised lighting level recommendations as published in the IESNA Lighting Handbook Ninth edition, according to Eric Richman, chair of the 90.1 lighting subcommittee.
