  1. ASHRAE Standard 90.1-2013 Aiming at 50% Energy Savings For 90.1-2013

  2. ASHRAE Standard 90.1-2013 • Background on Standard 90.1- 2013 • The “Goals” for 2013 • Changes under consideration • The Future

  3. 90.1-2010 – 2013 • ASHRAE Technology Committee - Ad-Hoc Committee on Energy Targets – June 2010 • Promote EUI as measurement • Encourage use of ASHRAE Stds 62.1 & 55 • SSPC 90.1 responsible for our energy targets • Standard 90.1 IS NOT the foundation for meeting Vision 2020 or NZEB • AEDGs are mechanism for NZEB

  4. ASHRAE Standard 90.1 Revision Goals • Technically justified • Simplicity • Flexibility • Enforceable

  5. 90.1-2010 – Major Step Title, Purpose & Scope change • Expand to new areas • Commercial/industrial equipment/processes • Identify & engage stakeholders

  6. ASHRAE Standard 90.1-2013 Timeline • MILESTONES • 90.1-10 Work Plan – 30% • 90.1-13 Work Plan – 50% • on regulated end use loads • 90.1-13 Work Plan – 40% • whole building (all end uses) • 90.1-13 Work Plan – EUI • 90.1-13 Work Plan – Alternate • Performance Methodology (APM) 30% 50% 40% APM 2004 Std 90.1-04 Future 2007 Std 90.1-07 2010 Std 90.1-10 2013 Std 90.1-13

  7. ASHRAE Standard 90.1 Sections • Section 1: Purpose • Section 2: Scope • Section 3: Definitions • Abbreviations • Section 4: Admin. And • Enforcement • Section 5: Building • Envelope • Section 6: HVAC • Section 7: SWH • Section 8: Power • Section 9: Lighting • Section 10: Elec. Motors • Section 11: ECB • Section 12: References • Appendices • Appendix C – Envelope • Appendix G - ECB

  8. ASHRAE Standard 90.1 • Since • July 1, 2010 • 2010 Users Manual • 23 New Addenda in process • 4 from previous cycle

  9. ASHRAE Standard 90.1 In Progress ENVELOPE • Building envelope (Addendum “bb” – 4th PR) • Door leakage • Cool Roof standards • Dynamic glazing & fenestration labeling

  10. ASHRAE Standard 90.1 In Progress LIGHTING • Escalator controls • Elevator lighting • LPD revisions • Electric motors • Electrical Metering • Branch circuit controls

  11. ASHRAE Standard 90.1 In Progress MECHANICAL • Commercial refrigeration • Heat pump efficiencies • SPVAC & SPVHP efficiencies • Transformer testing • Damper leakage

  12. ASHRAE Standard 90.1 In Progress MECHANICAL • Fan efficiencies –Advisory Public Review (APR) • Engaged interested parties • Set min Fan Efficiency Grade (FEG) > 67 • Based on AMCA 205-10 • Covers fan motor ratings > 1/6 hp • Does not cover fan systems • Addendum excludes • Fans with bhp< 5 • Fans covered by 6.4.1.1

  13. ASHRAE Standard 90.1 In Progress Energy Cost Budget • Cooling Towers • Laboratory Exhaust • Building Orientation • Fenestration • Temp & Humid Schds • Computer room criteria • (Addendum cj - 3rd PR)

  14. ASHRAE Standard 90.1 In Progress Energy Cost Budget - Renewables • Site-recovered & Site-generated energy credit allowed • Not considered “purchased energy” • Deducted from “proposed design” energy consumption • Credit < 5% for calculated energy cost budget

  15. ASHRAE Standard 90.1 Under Discussion Continuous Maintenance Proposal (CMP) • Data Centers PUE = Total Energy @ Meter ÷ Peak IT Equipment Energy

  16. ASHRAE Standard 90.1 Under Discussion Continuous Maintenance Proposal (CMP)

  17. ASHRAE Standard 90.1 Under Discussion Other Continuous Maintenance Proposals (CMPs) • Systems testing personnel limitations • Economizer revisions • Luminaire limitations • Definition of cooling design temperature • Revisions to evaluate systems with Appendix G

  18. ASHRAE Standard 90.1 Under Discussion Other Informal Concepts • Revisions to single & multi-zone VAV systems • PTUHP and DX equipment revisions • Occupancy controls for dedicated HVAC system • Energy recovery systems enhancements • Energy recovery for space heating • Cooling tower controls and efficiency

  19. 90.1-2010 – 2013 & Future • Wholisticsystems designs • Systems Design and subsystems effects

  20. 90.1-2010 – Future • Alternate Performance Methodologies • Determine “base minimum” using whole building designs • Explore regional utility rates • Explore time/demand rates • Consider water use and rates • Explore criteria metrics other than cost savings (e.g. system efficiencies) • Address renewables (site based & grid based) • Use AEDG format for the 90.1 standard

  21. 90.1– Moving Forward • Input Needed – Ideas Welcome • Designers • Equipment & Material interests • Code Officials • the list goes on ……… Come join the fun!
