ASHRAE Standard 90.1
• ASHRAE Technology Committee - Ad-Hoc Committee on Energy Targets – June 2010
SSPC 90.1 responsible for our energy targetsStandard 90.1 IS NOT the foundation for meeting Vision 2020 or NZEBAEDGs are mechanism for NZEBPromote EUI as measurement
90.1-2010 – Major Step
• Expand to new areas• Commercial/industrial equipment/processes
• Identify & engage stakeholders

Since July 1, 2010
• 2010 Users Manual• 32 New Addenda in
process• 4 from previous cycle
ASHRAE Standard 90.1In Progress
• Building envelope (Addendum “bb” – 4th PR)
• Door leakage• Cool Roof standards• Dynamic glazing &
fenestration labeling
ENVELOPE
• Escalator controls• Elevator lighting• LPD revisions• Electric motors• Electrical Metering• Branch circuit controls
LIGHTING
ASHRAE Standard 90.1In Progress
• Commercial refrigeration• Heat pump efficiencies• SPVAC & SPVHP efficiencies• Transformer testing• Damper leakage
MECHANICAL
ASHRAE Standard 90.1In Progress
•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 90.1In Progress
• Cooling Towers• Laboratory Exhaust• Building Orientation• Fenestration• Temp & Humid Schds• Computer room criteria
(Addendum cj - 3rd PR)
Energy Cost Budget
ASHRAE Standard 90.1In Progress
• 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 90.1Under 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
90.1-2010 – Future
• Alternate Performance MethodologiesDetermine “base minimum” using whole building designsExplore regional utility ratesExplore time/demand ratesConsider water use and ratesExplore criteria metrics other than cost savings (e.g. system efficiencies)Address renewables (site based & grid based)Use AEDG format for the 90.1 standard
