Title-24 vs. ASHRAE 90.1 for LEED-NCv2.2 EA Credit 1: LEED has stated that it will accept Title 24-2005 as an equivalent replacement for the ASHRAE 90.1-2004 code for the EA credit 1. LEED 2.2 requires the total energy use of the building (regulated and process loads) be used in the energy savings calculation for EA1. Title 24-2005 uses only regulated loads in the energy calculation. Since LEED 2.2 accepts Title 24-2005 as an ASHRAE 90.1-2004 equivalent, do the process loads need to be included in the Title 24 model for the LEED 2.2 EA credit 1 calculation? Or is the standard Title 24 analysis that considers only regulated loads the appropriate comparison?
