Note:1. Subscript 'w' refers to whole-window properties, which apply to all parameters except the damage-weighted fading
transmittance, Tdw. Uw is the whole-window U-value. SHGCw is the whole-window solar heat gain coefficient. Tvw is thewhole-window visible (light) transmittance.
2. Percentage improvement figures are compared with using base-case Generic Window 1 (3mm clear in std aluminium frame).3. A negative percentage improvement figure indicates performance worse than the base-case window and a positive
percentage improvement figure indicates performance better than the base-case window.4. Maximum air infiltration is 0.5 L/s.m2 at a positive pressure difference of 75 Pa as measured according to AS 2047.5. Static performance (Uw, SHGCw, Tvw, Tdw) calculated using Window 4.1 and Therm 2.1 software (Lawrence Berkeley
National Laboratory), 2000-2001.6. Annual energy performance (stars and % improvements) calculated using Nationwide House Energy Rating Software
(NatHERS) according to procedures of WERS 2000 (Australasian Window Council), www.wers.net.
