  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.

  4. ANSI/IESNA/ASHRAE Standard 100 Revision Timeline Standard 100 Revision Overview 6/27/2010 June 22, 2010 – 50% draft complete Sept 30, 2010 – 1st complete draft Dec 7, 2010 – SPC 100 Vote to approve draft standard for public review Spring, 2011 – Standard 100 public review

ANSI/IESNA/ASHRAE Standard 100 Revision Outline Standard 100 Revision Overview 6/27/2010 Title Purpose Scope Definitions Compliance Requirements Energy Use Analysis and Target Requirements Operation and Maintenance Requirements Energy Audit Requirements Implementation and Verification Requirements References

  6. Standard 100 Flow Chart Standard 100 Seek Compliance Compliance Requirements Section 4 Prioritize, Implement & Commission EEMs Section 8 Conduct Energy Audit Section 7 Implement Mandatory Operations and Maintenance Section 6 NO Does Building Meet Energy Target? Sect. 5 Identify Building Type, Climate Zone and Collect Energy Use Data, Section 5 Verify Energy Savings Section 8 Complete Compliance Forms for Buildings with Targets Section 4 Is there a Target for Building type? Section 5 YES Standard 100 Compliance YES Complete Compliance Forms for Buildings w/o Targets Section 4 Prioritize, Implement & Commission EEMs Section 8 Verify Energy Savings Section 8 Conduct Energy Audit Section 7 NO Standard 100 Revision Overview 6/27/2010

  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.
