Project information to inform annual energy use estimation For projects that did not create a model, provide USGBC with information to estimate project energy use in Arc [31] . Examples of information that may need uploading include:
-
General project information . Expected occupancy, age of the building, gross floor area, and location
-
High load amenity information . Any large process energy contributions to energy use, such as equipment for commercial kitchens, commercial refrigeration, laundry, data centers, laboratories, or manufacturing
-
Regulated energy information . Lighting power densities, fuel types, HVAC system types, and other factors
Sign-off on 10-year operational carbon projection USGBC will provide all LEED ID+C: Commercial Interiors projects with a business as usual (BAU) projection of the project’s operational carbon emissions over the next 25 years, based on the estimated annual energy use and the project’s current grid emissions factor. This BAU projection assumes that grid emissions factor starts with the latest national or regional coefficient, such as the subregional eGRID [32] coefficients in the US, and declines in a straight line by 95% over the next 25 years. This is meant to reflect the overall direction of grid decarbonization globally, and is not intended to be an exact prediction of individual project performance
The projection should educate owners, tenants, and designers on the carbon impacts of their design decisions over the next 10 years. Tenants, or owners in an owner-occupied space, must review the data and attest to the review.
