Document Revision History

Revision 0 February 27, 2007 Original work paper from February 2007 short form.

    Revision 1 October 12, 2007 Converted to new work paper format.

     Added DEER Differences, Codes & Standards, EM&V sections

    and analysis.

     Reduced the annual operating hours for the Misc. Commercial

    building type from 4,500 to 3,612.

     Reduced the peak demand Coincident Diversity Factor for the

    Misc. Commercial building type from 0.76 to 0.634.

     Misc. Commercial building type annual energy savings reduced

    from 243.00-to-195.048 kWh/fixture.

     Misc. Commercial building type peak demand reduction reduced

    0.0429-to-0.0358 kW/fixture.
