Seattle Energy Code -Update

This Thursday January 18 we presented a Seattle Energy Code update by John Hogan, Senior Code Development Analyst for the Seattle Department of Design, Construction and Land Use.
John focused on the lighting energy section of the code and the cities attempt to reduce the allowable lighting energy use by 10% beyond ASHRAE/IESNA Standard 90.1-2004.
Throughout the discussion there was not much disagreement with the proposal, mainly questions in regards to its impact on the use of certain lamps and equipment, as well as clarification regarding the LPD in specific spaces.

The question is: have we reached a threshold where we are compromising lighting quality in order to save lighting energy?
