Code change could increase high-performance window systems

‘Stretch' energy code in Massachusetts could mean more high-performance glazing installations.



A story on the USGlass News

Network states a recently adopted

code change proposal by the Commonwealth

of Massachusetts could

help spur increased use of high-performance glass and window systems in both

commercial and residential applications.


Appendix 120.AA , known as the

"stretch" code, is an optional appendix to the Massachusetts Building

Code 780 CMR that will be applied by Aug. 1, 2009. The stretch code is

similarly based on the IECC 2009 energy code, which will become the base energy

code in 2010, but with approximately 20% greater building efficiency

requirements, and a move toward third-party testing and rating of building

energy performance.
