Developed by the National Electrical Manufacturers Association’s (NEMA’s) “enlighten America” campaign. The checklist items for all buildings begin with establishing the proper light levels for the tasks, spaces, and people involved. Too little light and visibility — and productivity — can be compromised. Too much light and the result is waste. Controls are effective complements to daylighting by providing steady light levels despite daylight-quality changes caused by the time of day or weather. For industrial buildings and warehouses, the checklist is focused on specific areas, including exits and entrances, open and staging areas, aisles, restrooms, and many others.
