Reduce consumption of nonrenewable energy sources by encouraging the installation and operation of renewable electric generation systems.
10 Renewable energy system (maximum 10 points). Design and install a renewable electricity generation system. Use energy modeling to estimate both the energy supplied by the renewable energy system and the annual reference electrical load. Receive 1 point for every 3% of the annual reference electrical load met by the system.
Annual reference electric load is defined as the amount of electricity that a typical home (e.g., the HERS Reference Home) would consume in a typical year. The annual reference electric load must be determined using the procedures specified in the 2006 Mortgage Industry National Home Energy Rating Standards (HERS) Guidelines.
Annual reference electric load
= 10,000 KWh
Annual electricity consumption in LEED home
= 7,000 KWh
Annual electricity supplied by renewable energy system
= 1,800 KWh
Percentage of annual reference electric load supplied by renewable energy system
= 1,800 / 10,000
LEED points, under EA 10
= 18.0 ÷ 3 = 6.0 points
