Using the annual energy use data submitted, the project’s current grid data, and the project’s location, USGBC will generate a 25-year BAU projection of the project’s carbon emissions, including a comparison with a straight-line reduction.
Provide a high-level estimated end-use breakdown as shown in Table 1.

Building Performance Standard Business-as-Usual Projection
Projects subject to a carbon-based or energy use intensity (EUI)-based building performance standard (BPS) must create an ordinance-specific 25-year BPS-BAU projection with an overlay of the BPS caps. For EUI-based BPS, the BPS-BAU must be an energy BAU, and for carbon
