As defined in the C-PACE program guidelines, energy efficiency projects must include a formal evaluation of the energy consumption baseline and projected savings that is consistent with the (i) requirements of ASTM International Standard E2797: Standard Practice for Building Energy Performance Assessment for a Building Involved in a Real Estate Transaction; (ii) the ASHRAE Level 2 or 3 guidelines for energy audits or any comparable energy assessment guidelines, as applicable.
The methodology for the savings projections is determined based on the complexity of the project. For example, in a single measure, like-for-like equipment replacement project such as a boiler replacement, the required documentation can be less comprehensive than for a multi-measure, comprehensive project that involves interactive effects. For more information, refer to the C-PACEĀ Program Guide.
