Taylor,program manager.NFRCUpdateNational Fenestration Rating CouncilNew Image for NFRCIt’s official! The NFRC membership overwhelminglyadopted a new logo at the Spring 1997Membership Meeting in Nashville, Tennessee.The new multi-faceted logo reflects the manydifferent aspects of NFRC’s mission. The newlogo emphasizes the importance of both heatingand cooling performance of fenestration. Thequadrant design gives the appearance of a window,while symbolizing different climate regions.The new logo will begin to appear immediatelyon all NFRC promotional and marketing materials.NFRC-100 RevisedIn an effort to streamline certification procedures,NFRC has revised NFRC-100: Procedurefor Determining Fenestration Product ThermalProperties. Instead of requiring two separate teststo determine U-Factor values, manufacturers cannow validate their values through one initial test.U-Factor measures a product’s entire ability totransfer heat from inside the home to the outside.New Heating and Cooling RatingsUnder DevelopmentAt its spring, summer, and fall 1997 meetings,NFRC continued its efforts to develop consumerfriendlyheating and cooling ratings. The ratingswill make window shopping easier for consumersand builders, without sacrificing technological excellence.These ratings will provide energy performanceinformation in just two numbers—one describingperformance during the winter heating season, andthe other during the summer cooling season. Thenumbers, given on a scale from 0 to 10, will allowquick, accurate comparisons of the energy performanceof different products.NFRC Meeting ScheduleJanuary 21-22, 1998NFRC Task Group MeetingsHoliday Inn San Francisco AirportSan Francisco, CaliforniaMarch 29-April 2, 1998NFRC Spring MeetingLoews Annapolis HotelAnnapolis, MarylandFor more information on:• Administrative & Membership• Certification Agency Program• Communication and Education• Compliance Assurance Program• Laboratory Accreditation Program• Meetings/Newsletters• Product Certification Program• Publication OrdersContactNational Fenestration Rating Council1300 Spring Street, Suite 500Silver Spring, MD 20910 USATel: (301) 589-NFRCFax: (301) 588-0854e-mail: NFRCUSA@aol.comWeb: http://www.nfrc.orgBuilding Technologies ProgramEnvironmental Energy Technologies DivisionLawrence Berkeley National LaboratoryOne Cyclotron Road, Mailstop 90-3111Berkeley, CA94720 USAFirst ClassU.S. PostagePAIDBerkeley, CAPermit No. 1123Printed on recycled paper.Please recycle again
