ANSI/IESNA/ASHRAE Standard 100 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
• 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.

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/ft2-yr).

Building 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.
