- Credit 1 - Optimize Energy Performance
- Credit 2 - On-Site Renewable Energy
to decrease dependence on fossil fuel energy use by employing
on-site renewable energy self-supply systems.
Implement on-site renewable energy systems such that 2.5% (1 pt.),
7.5% (2 pts.), or 12.5% (3 pts.) of the total annual energy costs
are generated by on-site renewable energy systems.
- Contact local utilities or electric service providers to
determine if net metering is available.
- Consider photovoltaic, solar thermal, geothermal, wind,
biomass, and bio-gas energy technologies.
- The installation of renewable energy generation systems (wind,
PV, biomass etc.) may be incorporated into an education and
outreach program for an Innovation and Design point (IDc1).
- This credit has synergies with EAc1 energy saving calculations.
In a certain sense, renewable energy generation is rewarded twice
by the LEED rating system.
- Passive solar design, daylighting strategies, and ground-source
heat pumps are not eligible for EAc2.
- Project teams should pursue the many energy incentives and
rebates offered by California for renewable energy generation
- Consider use of on-site distributed energy such as fuel cells
and waste heat recovery.
- Useful references:
- 48% of all California LEED Certified projects achieved this
credit under LEED v2.1.
- California LEED Certified projects achieved 1.4 credits on
average for EAc2 under LEED v2.1.
