Why 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 compliance Provides product performance comparison and assists consumer to make informed decision Promotes energy efficiency by providing a base line for product development and improvement. Also creates market competition for improved products Consumer 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.

Requirements of a Successful Rating System Fair, accurate and unbiased Based on Science Provide Verifiable, Repeatable and Consistent Results Evaluation Based on Fixed Conditions Cost Effective for Adoption Industry buy-in

Structure Of A Rating Organization Governance Body Board of Directors which is balanced between Industry and Consumer interest representation Membership: Participates in the program and pays fees Committee responsible for development of procedures and standards Executive office and Staff: Carries out day to day operation and management Testing and Simulation Laboratories accredited by the Governing Body Service: Provides Energy ratings per prescribed standards Inspection Agency –Licensed by the Governing Body Service: Audits products which the participants rate.

Implementation of Successful Rating System Referenced by Codes and Regulations Promotional Programs like Energy Star Financial Incentives

Fenestration & Code IECC & 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.

Energy Policy Act 2005 & Energy Star Program

Incentive Program

Tax Credit the IRS has provided a “special rule” (on page 7 of the IRS notice 2006-26) 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.

Impact 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).
