The LEED-EB reference guide version 2.0, First Edition, June 2005, EA 2.1-2.4 states that up to four points can be earned by purchasing renewable energy credits based on a percentage of a the buildings annual energy consumption (60% for 4 points). It also states that a letter must be signed stating the intent to purchase the same amount or greater for the next performance period. If a LEED EB project uses a 3 month performance period, what is the minimum number of months that must be purchased to meet each of the point requirements, and may an additional innovation point be earned by purchasing a 5th point?
Because the minimum performance period for recertification (the \'next performance period\') is one year, for initial certification the commitment to purchasing the same amount of greater of renewable energy credits must be made for a full year following the original performance period. In order to achieve exemplary performance for this credit, the project team must purchase 75% or more renewable energy for the same period. A single ID credit point would be available for this approach. Applicable Internationally.
