LEED O+M: Existing Buildings | v2 - LEED 2.0

On-site and off-site renewable energy

EAc2 | Possible 4 points


Encourage and recognize increasing levels of on-site and off-site renewable energy in order to reduce environmental impacts associated with fossil fuel energy use.


Over the performance period, meet some or all of the building’s total energy use through the use of on-site or off-site renewable energy systems. Points are earned according to the following table. The percentages shown in the table are the percentage of building energy use over the performance period that is met by renewable energy.

Off-site renewable energy sources are as defined by the Center for Resource Solutions (CRS) Green-e products certification requirements or the equivalent. Green power may be procured from a Green-e certified power marketer, a Green-e accredited utility program, or through Green-e certified Tradable Renewable Certificates or the equivalent. At least 25% of any off-site green power or Green Certificates used to earn this credit needs to be from new sources (sources constructed after 1997). For on-site renewable energy that is claimed for LEED for Existing Buildings credit, the associated environmental attributes must be retained or retired and cannot be sold.

Up to the four-point limit, any combination of individual actions will be awarded the sum of the points allocated to those individual actions. For example, one point would be awarded for implementing 3% of onsite renewable energy. Two additional points would be awarded for meeting 30% of the building’s energy load with renewable power or certificates over the performance period.
