The Caltrans District 7 Headquarters Replacement Building in downtown Los Angeles, California will include a photovoltaic array that will reduce the percent of energy use in the building by more than 2.51%. The energy produced by the PVs will be fed directly back into the building, rather than into the energy grid. LEED 2.0 Reference Manual requirements for EA Renewable Energy Credit 2.1, Table 8 "Point Interpolation Table" indicates that the percentage of renewable energy can range from 2.51% - 7.50% to achieve one LEED credit. This is based on the statement on Page 144 of the LEED Version 2.0 Reference Manual, "The total percent reduction in energy use changes. This is because Credit 1 is based on grid energy that crosses the property line. When part of the building energy load is handled from an on-site generation source, it is deducted from the numerator in the calculation. To calculate the percent renewable contribution and the corresponding LEED points, use the interpolation rules as shown in Table 8." As the PV cells are an on-site energy generation source, will the project achieve a credit under EA 2.1, Renewable Energy, if the percent energy reduction is greater than or equal to 2.51% based on the Table 8 Interpolation Table? Further, we understand that the Table 8 Interpolation Table would allow us to apply this energy reduction to EA Credit 1, Optimize Energy Performance in addition to the Renewable Energy credit, because we will be reducing the numerator in the calculation by the percent reduction in energy. Please confirm credit items under EA 2.1 and 1.0.
