1 ASHRAE Standard Aiming at 50% Energy Savings For

2  Background on Standard  The “Goals” for 2013  Changes under consideration  The Future ASHRAE Standard

3 – 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 – Major Step Expand to new areas Commercial/industrial equipment/processes Identify & engage stakeholders Title, Purpose & Scope change

6 Timeline MILESTONES  Work Plan – 30%  Work Plan – 50% on regulated end use loads  Work Plan – 40% whole building (all end uses)  Work Plan – EUI  Work Plan – Alternate Performance Methodology (APM) ASHRAE Standard Std Std Std Std Future 30% 50%40%APM

7 ASHRAE Standard  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 Sections

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

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

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

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

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

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

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

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

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

17 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 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 – 2013 & Future Wholistic systems designs Systems Design and subsystems effects

20 – 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!
