The intent of LEED for Existing Buildings is to promote high-performance, healthy, durable,
affordable, and environmentally sound practices in existing buildings. It encourages owners
and operators of existing buildings to implement sustainable practices and reduce
environmental impact of their buildings over their functional life cycles.
For LEED for Existing Buildings certification, sustainable operations performance is being
measured for the building and site over a period referred to as the performance period. The
performance period is a continuous, unbroken time, without gaps. It must be a minimum of
three months for all prerequisites and credits except Energy and Atmosphere Prerequisite 2
Minimum Energy Efficiency Performance and Credit 1 Optimize Energy Performance, which
have a duration of one year.
