Intent

Reduce consumption of nonrenewable energy sources by encouraging the installation and operation of renewable electric generation systems.

Requirements

Prerequisites

None.

Credits

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.
For example,
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
= 18.0%
LEED points, under EA 10
= 18.0 ÷ 3 = 6.0 points

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
