Ensuring Lighting Duality and Lighting Efficiency: A New Basis For Lighting Standards James A. Wise Pacific Northwest Laboratory, Richland, Washington, USA Barbara K. Wise Pacific Northwest Laboratory, Richland, Washington, USA Susan F. Savage Pacific Northwest Laboratory, Richland, Washington, USA Summary This paper reports the first year results of a major United States Department of Energy (DOE) study that assesses potential lighting quality impacts of lower lighting power density levels (lpds in watts/m_2) under consideration for DOE's commercial buildings energy standard. This standard sets energy performance requirements that are mandatory for federal buildings and voluntary for the private sector in the United States. New energy legalisation passed during 1992 will make it mandatory in the future that individual States adopt energy codes at least as stringent as the Federal standard. The research performed under this study is providing a new basis for setting DOE power density levels, in order to assure that quality of lighting is maintained as lighting energy is improved.
