Windows Energy Ratings Scheme
2008 WERS Certified Products Directory – NFRC
NOTES
- Uw is the whole window U-value
- SHGCw is the whole window solar heat gain coefficient
- Tvw is the whole window visible (light) transmittance
- Percentage improvement figures are compared with using base-case Generic Window 1 (3mm clear in standard aluminium frame)
- A negative percentage improvement figure indicates performance worse than the base-case window
- A positive percentage improvement figure indicates performance better than the base-case window
- Maximum air infiltration is 5.0L/s.m2 at a positive pressure difference of 75 Pa as measured according to AS 2047
- Static performance (Uw SHGCw Tvw Tdw) calculated using Window 5.2 and Therm 5.2 software (LBNL), 2000-2003
- Annual energy performance (stars and % improvements) is calculated using Nationwide House Energy Rating Software (AccuRate) according to procedures of WERS 2008.
