A recast of a presentation done for the Fairfax Chapter of Association of Energy Engineers in November of 2013. Presentation focuses on the the Advanced Energy Design Guides published by ASHRAE with association of AIA, USGBC, and IES with funding and technical support from DOE, NREL, and PNNL. In addition, the DOE Advanced Retrofit Guides are also discussed. Both sets of guides are available for download from this resource database.

"Improved lighting efficiency has long been a major strategy to reduce the energy use in buildings. These savings have traditionally come from improved efficiency of lamps and ballasts. Today, deep energy reductions and Zero Net Energy (ZNE) are possible by continually controlling each of these efficient fixtures in response to varying details within the space. This guide provides an overview of luminaire-level lighting control (LLLC). The full LLLC approach provides controllability at each fixture with real-time energy tracking and data collection."
"When designers of the first net zero energy school in the U.S. considered how they would approach the lighting design differently using today’s LED technology, the results extended far beyond just switching out the lightbulbs. The hypothetical redesign of Richardsville (Ky.) Elementary classrooms involves rethinking the daylighting design based on the evolution of LED lighting and the cheaper cost of photovoltaics (PV)."
