' The National Fenestration Rating Council (NFRC) is a non-profit public/private group of manufacturers, builders, designers, specifiers, code officials, utilities, regulators and consumers formed to establish a national energy performance rating system for fenestration products. Sanctioned by the federal government under the Energy Policy Act of 1992, NFRC will, over the next several years, in addition to � U-Factor (thermal transmission), rate other factors, including solar heat gain, optical properties, air infiltration and condensation resistance. It is important to note that the NFRC is not setting minimum performance standards or mandating specific performance levels. NFRC has established a single rating system with a rigorous process for comparing product performance. By certifying and labeling their ,� products in accordance with the NFRC program, manufacturers demonstrate their commitment to provide accurate energy performance information. Whole Product Performance � NFRC ratings are based on"whole product performance".Although a window, door, or skylight may have high performance glazing, its overall performance may be reduced by a poorly performing frame. Similarly, a very energy efficient frame may be wasted on ineffective glazing and sealing. Whole product performance helps builders and consumers compare products of different � construction and attributes directly. When reading a NFRC Label, it is important to remember that the U-Factor, SHGC, and VT,values represent the whole window, not the center-of-glass � NFRC Labeling Certification and Labeling Process Window and door manufacturers attempting to certify their fenestration products are required to have them evaluated by two different types of independent NFRC accredited laboratories. ' 1. The first type of laboratory is a computer simulation lab which evaluates a window or door's thermal efficiency by computer simulation programs. The computer program takes into account the producYs frame and glazing system attributes and derives an overall product U-Factor. ' 2. The second type of laboratory is a physical testing laboratory which takes an actual product and evaluates it in a thermal chamber.The physical test lab will also derive an overall product U-Factor.
