Revision Title, Purpose and Scope
• TITLE: ENERGY EFFICIENCY IN EXISTING BUILDINGS
• PURPOSE:
– This standard provides criteria that will result in energy efficiency in existing
buildings.
– This standard is directed toward:
a. Providing procedures and programs essential to energy efficient operation,
maintenance, management and monitoring;
b. Increasing the energy efficiency of the energy-using systems and
components; and
c. Upgrading the thermal performance of the building envelope.
• SCOPE: This standard applies to existing buildings, portions of buildings,
and building complexes, including the envelope and all systems in the
building. This Standard excludes industrial and agricultural processes in
buildings for which the energy use targets do not include those
processes.

Building Baselines and Targets
• Benchmarks are being compiled from CBECS 2003
for building type and climate zone.
• Authority Having Jurisdiction can pick level of
compliance in reference to Benchmark for Target
(e.g. Federal Buildings may pick 30% lower).
• Owner to conduct energy use analysis from utility
bills to get Baseline Energy Use Intensity (kBTU/ft2yr).

Building Baselines and Targets
• If building type is listed in Target List,
compare Baseline to Target.
– If Baseline <= Target, requirement of Sec. 5 met.
– If Baseline > Target, must complete Sec 7 & 8.
• If building type not listed in Target list, must
complete Sec 7 & 8.
