Through Addenda • Prior to public review – Change proposed – Subcommittee(s) develop drafts – SSPC discusses drafts – SSPC votes for public review and publication – SPLS and IES vote for public review and publication • BOD - TPS changes • Public review – Announced – Comments made – Comment responses voted on – If changes made, another PR voted on – Commenters reply • If resolved, addendum moves forward • If unresolved SSPC must revote with that knowledge Where have addenda come from? • You • Other publications – Advanced Energy Design Guides – California Title 24 – ASHRAE Standard 189.1 • TC’s • Stakeholders (working groups) • Energy conscious owners • SSPC 90.1 volunteers – 4 meetings per year (3-4 days each, 8 am – 9 pm) – Additional web meetings – Monthly (or more often) conference calls SSPC 90.1 Accomplishments 06/2007 through 07/01/2010 • 118 Addenda processed – 60 approved – 26 no unresolved objections, moving forward – 26 with knowledge of objections – 2 still in public review – 4 unlikely to be ready in time for 90.1-2010 • 90.1-2007 publications • User’s Manual • Supplement (1Q-2009) incorporates 20 addenda • 2010 User’s Manual in progress • Interpretations • 29 official • ~31 unofficial Addenda to 90.1-2007 Published 2008 Supplement (20 addenda) • • • • • • • • G – Metal buildings H – Dual minimum zone controls I – Exterior lighting L – Closed circuit cooling towers addition M – Chiller efficiencies, Paths A & B N – Single zone VAV control Q – Vestibules in Climate Zone 4 R – Change Appendix G to normative (mandatory language) • S – Heat pump part load efficiency • AW – Guest room lighting Published 2008 Addenda to 90.1-2007 Approved Approved by BODs, but not yet published (40) • • • • • • • • • • • • D, AB – Daylighting E – Revision of air-to-air energy recovery requirements AF – Pipe sizing based on hours of operation AK – Pump pressure optimization AS – Laboratory exhaust AV – Lighting alterations BC – Skylights in non-conditioned spaces BG – Water-to-water heat pump efficiency requirements BH – Supply air temperature reset BP – Lighting control BQ – Retail lighting allowance power reduction BW – PTAC efficiency requirements Finished Addenda to 90.1-2007 Finished, but not yet approved • F – Roofs, including “cool” and vegetative • • CB – Damper leakage rates CE, CE CF – Lighting control • • AL – Skylights in large spaces AQ – Title Purpose and Scope – includes commercial processes • CK – Ventilation reset • • AX – Kitchen hoods BF – Continuous air barrier • BI – Pipe insulation • BN – Fenestration orientation • BT – Adjustment for centrifugal chillers at non-standard conditions • BY – Lighting power densities CO2 TOD OCC CO2 TOD OCC • CO – AC and condensing unit efficiency requirements • CP – VRF efficiency requirements • CT – Daylighting threshold • DD - Toplighting Addenda to 90.1-2007 Action taken June 2010 • BB – Envelope, opaque and fenestration • BU – Datacenters • CX – 40% WWR option • CY – Economizers • DF – Elevators • DH – Renewable energy modeling • Di – Garage ventilation Action taken at these meetings ASHRAE Standard 90.1-2010 (AQ) Purpose “To establish the minimum energy efficiency requirements of buildings, other than low rise residential buildings, for: 1. design, construction, and a plan for operation and maintenance, and 2. utilization of on-site, renewable energy resources ” ASHRAE Standard 90.1-2010 (AQ) Scope • new buildings and their systems • new portions of buildings and their systems • new systems and equipment in existing buildings • new equipment or building systems specifically identified in the standard that are part of industrial or manufacturing processes ASHRAE Standard 90.1-2010 (AQ) Does not apply to • a. single-family houses, multi-family structures of three stories or fewer above grade, manufactured houses (mobile homes), and manufactured houses (modular), or • b. buildings that use neither electricity nor fossil fuel 2010 90.1 Progress Indicator Information As of June 29, 2010 ●XX.X% energy savings compared to 90.1-2004 – assuming same ventilation rate ●YY.Y% energy savings compared to 90.1-2004 – assuming updated Standard 62.1 ventilation rates Stay tuned for the 11:00 Session Bing Liu and Steve Skalko Future Addenda • Open to your suggestions through the Continuous Maintenance Proposal process • All meetings open to the public • Hard working members are welcome Remember… • Minimum standards define the worst buildings allowed • Increased stringency in minimum standards is – Possible – Being done via a public consensus process • An important step on the march to net-zero energy use intensity for some buildings Thanks to… • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Mark Hydeman Steve Skalko Jerine Ahmed Susan Isenhour Anderson Wagdy Anis Pete Baselici Jeff Boldt Dave Branson Keith Emerson Drake Erbe Jim Garrigus Jason Glazer Pekka Hakkarainen Richard Heinisch Ned Heminger John Hogan Hy Kaplan Michael Lane Dick Lord Ron Majette Itzhak Maor Jim McClendon Michael Mehl Harry Misuriello Frank Morrison Tim Peglow Eric Richman Maria Spinu Christian Taber • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Mike Tillou Martha VanGeem Mike Waite Mack Wallace Richard Watson Jerry White Ron Burton Charles Cottrell Craig Drumheller Allan Fraser Ron Kurtz Steve Rosenstock Frank Stanonik Karim Amrane Ernie Conrad Chuck Foster Chad Groshart Merle McBride Ken Sagan Randy Blanchette Don Brundage Brian Hahnlen Susanna Hanson Jonathan Humble Ray McGowan Mike Rosenberg Marty Salzberg Jeff Stein Wayne Stoppelmoor • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Bill Talbert Dan Walker Jim Bowman Jim Calm Tom Culp Darryl DeAngelis John Dunlap Krishnan Gowri Mark Halvorson David Handwork Scott Hintz Tianzhen Hong Ron Jarnagin Michael Jouaneh Larry Kouma Bing Liu Frank Myers Jeff Park Robert Ross Cedric Trueman Emily Young Randy Casteel Pat Chinoda Paul Lindahl Ken Luther Rick Pavlak Leon Shapiro Jim Watts Rita Harrold • • • • • • • • • • • • • • • • • Doug Reindl John Montgomery David Schaaf Dennis Sczomak David Weitz Robin Wilson Ken Brendan Lawrence Brown John Lewis Bill Holy Frank Jakob Michael Woodford Tony Arbore Todd Brown Leo Smith Dennis Stanke Public • ASHRAE/IES Cassandra Craig Beverly Fulks Steve Hammerling Bruce Hunn Susan LeBlanc Jeff Littleton Judy Marshall Cindy Michaels Angela McFarlin Mark Owen Elizabeth Parrish Lilas Pratt Claire Ramspeck Stephanie Reiniche Amelia Sanders Emily Scott Emily Sigman Matt Walker Mark Weber Jan Young SPLS Carol Marriott Standards Committee Steve Bushby Technology Council Tom Watson Boards of Directors Kent Peterson Bill Harrison Gordon Holness Lynn Bellenger Steve Ferguson ASHRAE Staff Liaison aka “Radar” Commenters NMHC GANA Presenters at meetings CMP proposers Interpretation requesters PNNL Staff (analysis) All our families Questions?
