Make final calculations of the estimated building energy loads. Confirm that renewable energy generation capacity is 2.5% of building energy, at minimum for the LEED credit, or that the project’s goals are met.
This credit involves the use of an Environmental Impact Calculator & USGBC Credit Calculator which will be available for use by projects participating in the pilot. USGBC has not made it available for public viewing. To access the calculators, register your project for the credit (see Resources).
If your project has no cooling system or uses a system without refrigerants, you can achieve the credit through Option 1 (“do not use refrigerants”). Document your credit compliance path with appropriate supporting documents by completing the submittal template and providing cut sheets or other confirmation of the system type.
Run preliminary water use calculations to establish the baseline water use and confirm goals for water-use reduction. This should include clearly identifying target flow and flush rates for fixtures. This credit only includes core water uses—bathroom sinks, toilets, urinals, showers, and kitchen faucets.
Submit documentation to LEED Online. This will include filling out the LEED Online Submittal Template, which requires a number of inputs on total electrical consumption (or default values) and details on the green power purchased. You will also need to upload a proof of purchase for two years of green power—see the Documentation Toolkit for an example.
Call several green power providers to get a preliminary estimate of the cost to buy green power for 35% of the assumed, actual or default electricity consumption.
