Under the LEED v4 rating system, the “On-Site Renewable Energy” credit has been renamed EA Credit 5, the “Renewable Energy Production” credit. There is also an added provision to account for solar gardens and community renewable energy systems in the overall percentage of renewable energy production. The number of maximum LEED points that can be awarded for this credit has changed.
The benefits of implementing solar technology are closely aligned with the overarching goals of LEED, encouraging decreased carbon emissions, reduced reliance on traditional energy sources, improved air quality, and better building decisions. Converting just 50 kilowatts of power from gas to solar every month saves 732 pounds of carbon dioxide emissions annually.
Solar projects can provide a major contribution toward LEED certification. The primary LEED category pertaining to solar is the “Energy & Atmosphere” category, specifically EA Credit 2, the “On-Site Renewable Energy” credit.
The number of LEED points awarded is determined by the percentage of the facility’s energy costs that are offset by on-site renewable energy. Project performance is calculated by expressing the energy produced by renewable systems as a percentage of the building’s annual energy cost and using the table below to determine the number of points achieved.
