ENERGY STAR ® Qualified Fenestration Products ENERGY STAR Meeting – June 4, 2008 Steve Hopwood Office of Energy Efficiency

Program Status Manufacturers: 240 Dealer Locations: 175 Trade Allies: 5 Over 111,000 product models listed in database, consisting of: –80% window models –12% swinging door, sidelite, transom models –7% sliding glass door models –1% skylight models

Program Successes Part of ECOenergy Retrofit Program Part of ENERGY STAR for New Homes Used as a basis for a number of provincial and utility market transformation programs Levels used for building code and regulation initiatives: –Ontario – Maximum U 2.00 or Minimum ER 17 – Part 9 windows and sliding glass doors –British Columbia – 2009 – Maximum U 2.00 for Part 9 windows and doors (solid wood doors maybe exempted) and a minimum value for unit skylights TBD –Quebec and Ontario considering a regulation as well

How to Apply If products are certified for thermal performance and tested for air-tightness – contact NRCan – ask for an application kit Complete and sign an agreement Register your product models If no products are certified then contact one of the listed certification agencies (CSA, QAI, Intertek, NFRC) If not tested for air-tightness – contact certification agency or an accredited test laboratory

Technical Specification Currently Under Review What prompted this review? Canadian market shifting towards more energy efficient fenestration products - need to maintain ENERGY STAR as a premium symbol of energy efficiency. Ontario mandated current Zone A levels. B.C. will do the same in Concerns expressed over the inclusion of very low solar gain products. Requests from door industry to have separate levels for doors based on amount of glazing. U.S. Department of Energy (DOE) is seriously considering making the U.S. ENERGY STAR program more stringent.

Changes Under Consideration At This Time More stringent levels for each zone for all products – possibly introduced in two phases New separate level table for doors – levels would vary based on the amount of glazing Introduce a minimum solar gain requirement Full structural certification for all products to AAMA/WDMA/CSA 101/I.S.2/A440 IGMA/IGMAC/IGCC IG Unit certification Introduce a minimum air tightness requirement for swinging doors and skylights – make current air tightness requirement for windows and sliding glass doors more stringent NO zone boundary changes are being considered at this time.

Labelling Guidelines Also Under Review NRCan is also conducting a review of the labelling guidelines for ENERGY STAR. Possibilities: –Require use of certification agencys labels. –Require use of ENERGY STAR Fenestration Qualification Label (FQL). –Expand current FQL to include specific ratings and other information.
