6Why Rating is important Policies – Regulations Are difficult to implement and enforce unless one has the infrastructure to support compliance (ratings, certification, product testing, quality control, whole building integrated performance)Helps to verify code complianceProvides product performance comparison and assists consumer to make informed decisionPromotes energy efficiency by providing a base line for product development and improvement. Also creates market competition for improved productsConsumer benefit (assured payback, Insurance, tax incentives, and etc.Many reason exist making the rating of fenestration products necessary. NFRC ratings enable code bodies, consumers, designers, building officials and others to reference accurate fenestration energy ratings. NFRC is pursuing international harmonization is several countries including Canada, European union, India, china and Russia.
7Requirements of a Successful Rating System Fair, accurate and unbiasedBased on ScienceProvide Verifiable, Repeatable and Consistent ResultsEvaluation Based on Fixed ConditionsCost Effective for AdoptionIndustry buy-in
8Structure Of A Rating Organization Governance BodyBoard of Directors which is balanced between Industry and Consumer interest representationMembership: Participates in the program and pays feesCommittee responsible for development of procedures and standardsExecutive office and Staff: Carries out day to day operation and managementTesting and Simulation Laboratories accredited by the Governing BodyService: Provides Energy ratings per prescribed standardsInspection Agency –Licensed by the Governing BodyService: Audits products which the participants rate.
9Applicable ISO Standards ISO – Thermal Performance of Windows, Doors and Shading Devices — Detailed CalculationsISO 12567: Thermal performance of windows and doors -Determination of thermal transmittance by hot box method —Part 1: Complete windows and doors andPart II: Roof windows and other projecting windowsISO Glass in building-Determination of light transmittance, solar direct transmittance, total solar energy transmittance, ultraviolet transmittance and related glazing factors

19Fenestration & CodeIECC & IBC International (Energy Conservation Code & International Building Code)IECC and IBC’s Energy Code require rating for Residential and Non-Residential and specify NFRC certification for compliance.ASHRAE (American Society of Heating, Refrigeration & Air Conditioning Engineers)ASHRAE 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings require U-factor and Solar Heat Gain and specify NFRC certification for compliance.ASHRAE 90.2: Energy Standard for Low-Rise Residential Buildings require U-factor and Solar Heat Gain and specify NFRC certification for compliance.The IECC and ASHRAE are the two largest national building codes in the United States. Each of these references NFRC Ratings. If a building uses non NFRC rated windows the design is penalized by forcing the designer to use default tables. Default tables are worse case scenario ratings that unrated windows must use. Using NFRC rated windows simplified the building inspectors job by ensuring that the building complies with these national codes.
22Tax Creditthe IRS has provided a “special rule” (on page 7 of the IRS notice ) for claiming the residential tax credits with Energy Star windows:.03 Special Rule for Energy Star Windows and Skylights. A taxpayer may treat an exterior window or skylight that bears an Energy Star label and is installed in the region identified on the label as an Eligible Building Envelope Component and may rely on such Energy Star label, rather than on a manufacturer’s certification statement, in claiming the § 25C credit.
23Impact Rating Can Have in The Market Place The impact of successful NFRC rating program, in the year 2003 in the USA, 41% of all conventional residential windows were energy rated and were classified as Energy Star® Windows; which would not have been possible without NFRC ratings. As a result, NFRC was active in saving over 7 billion BTU’s (and 2 million kW’s peak load) in just one year (2003).
