GB6: Renewable Electric Generation

(5-11 points)

Purpose

Reduce consumption from non-renewable sources.

Criteria

Install a renewable energy technology or demonstrate future installation with deed restriction. The technology must either: distribute electricity to multiple buildings in the community or harvest and return energy to the grid. Points are awarded based on the percentage of the projected electricity use of all buildings within the community supplied by the technology. Projects may use the chart below as estimated electricity use per building type or can rely on building-specific energy modeling.

The strategy must provide a community-wide system. Any systems localized to individual homes/units will be awarded through the appropriate EarthCraft building program (ECH or ECMF).

If solar electric is the technology used to fulfill this credit, conduct a solar access analysis and clearly identify the areas or lots ideal for this technology. Ideal areas receive full sun at noon on the winter solstice (December 21st) and have no more than 50% of the area shaded at 9:00 AM and 3:00 PM on the summer solstice (June 21st).

Estimated Annual Electricity Usage:

Space Type	Kwh/ft2 per year of conditioned space.
Certified Commercial	5
Non-Certified Commercial	6
EC Single Family	5
EC Multi-Family	4
Retail	7.5

Percentage of projected electricity usage:

Percentage of Total Projected Electricity Use for Provided by Alternative Technology	Points
2%	5
5%	7
8%	9
11%	11

Projects may earn a maximum of 20 points from the District Heating/Cooling, Renewable Electric Generation and Alternative Thermal Production credits.

Verification 

• Narrative describing the renewable energy system to be installed. 
• Calculation of projected energy use for all structures within the project and amount of electric energy that will be produced by the renewable energy system. 
• Utility installation plan.

OR 

• Controlling documents such as deed restrictions.
