Pts 2.2 1 1 1 ∗ • LEED 2009 requires 10% or 5% improvement in building energy performance for new and existing buildings, respectively in the prerequisite based on ASHRAE 90.1-2007 Appendix G while LEED 2.2 EAc1 had the first 2 points required for 14% and 7% reductions, respectively based on ASHRAE Self Storage Buildings (<50,000 sf) based o

Pts 2009 3 2 1 • The prescriptive paths for LEED 2.2 EAc1 are now also a part of the prerequisite and may also earn some EAc1 points. Of note: • Certain Mandatory Measures are still required for all projects in LEED 2009 and are part of ASHRAE 90.1-2007. • Option 1 subtracts on-site renewable energy from the energy used (proposed perfor
