Guidance for determining office-equipment heat gain is contained in a new standard from ASHRAE.
“Most plug loads operate at a fraction of their nameplate electrical load, so, as a result, produce significantly less heat load than engineers may use in their cooling-load calculations based on those nameplate values,” Glenn Friedman, chair of the Standard 203 committee, said. “This can result in oversizing of air-conditioning equipment, resulting in extra initial cost for that equipment as well as higher operating cost.”
The cost of Standard 203-2014 is $35 for ASHRAE members and $41 for non-members. Copies can be ordered by phone at 1-800-527-4723 (United States and Canada) or 404-636-8400, by fax at 678-539-2129, or online at www.ashrae.org/bookstore.
