- Why NFRC?
- 	_***CREDIBILITY***_
- Represent Multiple Stakeholders
- Develop Consensus Standards
- NFRC Accredited Labs
- Third Party Certification

## REMEMBER!

_***Look for System Performance***_
- - GLASS
- - EDGE
- - FRAME
_***For Energy Performance Ratings***_

- Introduction to NFRC

## Introduction to NFRC

- Energy Performance Standards and Ratings
- U-factor (thermal transmission) – NFRC 100
- SHGC (Solar Heat Gain) – NFRC 200
- VT (Visible Transmittance) – NFRC 200
- Air Leakage – NFRC 400
- Condensation Resistance – NFRC 500

## Building Applications

- NFRC Addresses both Manufactured Products and Site-Built (Field Assembled Products).
- Utilize the same technical procedures (computer simulation/modeling; Validation testing; 3rd party verification)
- Provide information in different way (label vs. label certificate
- Mfr. vs. Responsible party

## NFRC LabelsManufactured Products

## Site Built

## To maintain the technical credibility of NFRC standards
To keep up with current technology (improvements in modeling, heat transfer calculations)
For “harmonization” (international standards; standard sizes)
To reduce marketplace confusion (two sizes/ratings on the label)
To maintain the four-year cycle of reviewing and publishing NFRC standards

## Changing from NFRC 100-1997 to 
NFRC 100-2001
Size Changes
Modeling changes (dividers)
Rating of Skylights – 20 degree slope
Application of ISO 15099 (heat transfer)

## Only one size in NFRC 100-2001 (rather than a residential and nonresidential size).

## Mfrs. may use current (1997) ratings and labels (two size ratings) until they expire.
Mfrs. may switch to one size label without recertifying, but must use 1997 RES rating and must indicate (on label) the rating is based on 1997 procedures.  
Windows can be submitted for rating to NFRC 100-2001 on 1/1/03; however, ratings (CAR) will not be issued until April 1, 2003. 
April 1, 2004 labs will only follow 2001 ratings and the new label will only incorporate new (2001) ratings.

## BENEFITS OF NFRC PROGRAM

**Addresses the complexity of current fenestration products**
**Provides a means for manufacturers to take credit for nuances and refinements to product design, thereby giving an incentive to and rewarding innovation**
**Simulation provides an inexpensive means to explore options during the design phase**
**Involvement of independent laboratories and IA’s provides architects, engineers, designers, contractors, consumers, building officials, and utility representatives with greater confidence that the information is unbiased**

## BENEFITS OF NFRC PROGRAM

**By requiring simulation and testing, there is an automatic check on accuracy ***(remedies a shortcoming of previous State Energy Code that relied on testing alone, which allowed manufacturers to perform several tests and then use the best one for code compliance)*
**The certification process indicates that the manufacturer is consistently producing the product that was rated*** **(this corrects a past concern where manufacturers were able to make an exceptionally high quality sample and obtain a good rating in a test, but not consistently produce that product)*
**NFRC Label Certificate that can be used by the building inspector to quickly verify Energy Code compliance**

## What’s New at NFRC?

- Can rate and label ‘tubular daylight devices” for U-factor
- Solar Calorimeter - can test, rate and label products for SHGC ratings (glass/acrylic block, etc.)
- Entry Doors (w/ 1⁄4, 1⁄2, 3⁄4 glass) energy ratings and labels
- Began work on rating attached films
