NEMA Updates White Paper on Lighting Controls Terminology

The National Electrical Manufacturers Association (NEMA) in Rosslyn, Va., published an updated white paper to clarify the terminology used in design and specification of daylight responsive lighting controls. NEMA LSD 64-2014 Lighting Controls Terminology.

The white paper, originally published in 2012, defines terminology related to controls for lighting systems for non-residential and residential applications. The goal of LSD 64 is for NEMA definitions to ultimately be used as the definitive reference for codes, standards, and legislation. This will eliminate the creation of new meanings for already defined terms, will minimize misapplication of controls terminology, and will eliminate the need for customized glossaries and terminology sections, NEMA said in a release.

The white paper was developed by reviewing every known description for lighting control terminology, and represents a standards working group ultimately agreeing upon best definitions. The working group reviewed definitions from documents such as American Society of Heating and Refrigerating and Air Conditioning Engineers standards, Illuminating Engineering Society of North America Handbook, NEMA guides, and all energy codes in use at the time, including California Title 24.

NEMA LSD 64-2014 may be downloaded at no cost on the NEMA website.
