The Illuminating Engineering Society, in partnership with the Lighting Controls Association, has published LEM-7, Lighting Controls for Energy Management, a detailed guide to energy-saving lighting controls. The publication was written by Craig DiLouie, LC in support of the IES Energy Management Committee.
The 48-page 8.5×11 guide, which is available for $35 (IES members) and $50 (non-members), was written to help designers, users, commissioning agents and other interested parties understand energy-saving strategies, design considerations, equipment, the variety of communication protocols and the importance of commissioning for lighting control systems installed in both interior and exterior applications in all types of buildings.
