Window-wall ratio amendment fails


Feb. 24, 2014 – The ASHRAE Standing Standard Project Committee 189.1 Workgroup
has officially voted down changes that would have reduced the
standard's allowable window-to-wall ratio to 25 per cent. The 189.1
standard is ASHRAE's green building standard for high-performance,
sustainable buildings and is being developed in partnership with the
U.S. Green Building Council, the body that oversees LEED certification.
With the defeat of the amendment, the window/wall ratio in 189.1 remains
at 40 per cent.

Common sense has prevailed," Margaret Webb, executive director of the Insulating Glass Manufacturers Alliance commented. "IGMA is very pleased with the recent ASHRAE 189.1 decision to unanimously withdraw the most recent proposed change to reduce the WWR requirements. This is the second time the industry has had to fight this issue. As with ASHRAE 90.1, the proponents of this change did not provide any technical justification. This is a major success for the industry and many thanks to Dr. Tom Culp who championed this cause on behalf of 126 individual companies and 13 trade associations representing the majority of the industry."
