ENERGY STAR® QualifiedFenestration Products

ENERGY STAR Meeting – June 4, 2008Steve 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 2009.

• 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 agency’s labels.

– Require use of ENERGY STAR Fenestration Qualification Label (FQL).

– Expand current FQL to include specific ratings and other information.
