ASHRAE Standard 90.1-2013 Aiming at 50% Energy Savings For 90.1-2013
2
Background on Standard 90.1- 2013 The “Goals” for 2013 Changes under consideration The Future ASHRAE Standard 90.1-2013
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 Expand to new areas Commercial/industrial equipment/processes Identify & engage stakeholders Title, Purpose & Scope change

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 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 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 Energy @ 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

90.1-2010 – 2013 & Future Wholistic systems 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
