3. ANSI/IESNA/ASHRAE Standard 100 Revision Title, Purpose and Scope Standard 100 Revision Overview 6/27/2010 • 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.

7. Building Baselines and Targets Standard 100 Revision Overview 6/27/2010 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).

8. Energy Use Benchmarks Standard 100 Revision Overview 6/27/2010 • Usage per square foot • Compare buildings of similar use-type and climatic conditions

9. Energy Use Targets Standard 100 Revision Overview 6/27/2010 Compare buildings of similar use-type and climatic conditions using statistical distribution

10. Energy Use Analysis Site Energy Used “to Keep It Simple.” On-site Power Generation Included “to Keep It Simple.” Control Volume around Building and Building Systems Standard 100 Revision Overview 6/27/2010

11. Building Baselines and Targets Standard 100 Revision Overview 6/27/2010 • 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.
