How does my onsite green power (solar or wind) affect my metrics (score, Source EUI)? Follow

Onsite green power is not subject to traditional generation, transmission, and distribution losses.  As long as you retain the RECs, this benefit is reflected in your ENERGY STAR score and Source EUI by assigning onsite electricity a source conversion factor of 1.0 rather than the 3.14 value that is used for grid-sourced electricity.  As such, a property with onsite solar or wind power is likely to receive a higher score.

The electricity use from onsite solar and wind must be reported and included in your total energy consumption. The use of onsite green power is part of your building's energy consumption (i.e. the energy requirement of your property).

For more information, refer to our technical reference on Green Power.
