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
- Providing procedures and programs essential to
energy efficient operation, maintenance,
management and monitoring - Increasing the energy efficiency of the
energy-using systems and components and - 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.

7Building 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/ft2-yr).

11Building Baselines and Targets
- If building type is listed in Target List,
compare Baseline to Target. - If Baseline lt Target, requirement of Sec. 5 met.
- If Baseline gt Target, must complete Sec 7 8.
- If building type not listed in Target list, must
complete Sec 7 8.
