The appropriate treatment of task lighting for energy code compliance has always been a potentially confusing issue. The intent of ASHRAE Standard 90.1-2007 (as well as previous editions back to 1999) and the International Energy Conservation Code (IECC) (including editions back to 2003) is for task lighting to be included in compliance calculations when it is part of the lighting design. This applies to office spaces where task lighting is common, as well as other spaces where task lighting may appear in various forms.
