PGE - Window Selection for New & Existing Homes

Wednesday, May 9, 2012 - 9:00am to 4:30pm

Also Offered April 10 (Tuesday, 9:00 am to 4:30 pm) Santa Rosa--Builders Exchange
Description Windows dramatically affect residential space conditioning costs and occupant thermal comfort. Upgrading existing or code minimum windows can save significantly on heating & cooling costs, but using the wrong window for any climate can actually increase energy costs. This class explains how to evaluate & select the most appropriate window technology for a given California climate. Topics include NFRC labels, new low-E and spectrally selective coatings, advanced frame & spacer technology, and how to properly flash windows during installation.
Audience Level This class will be most useful to those who are familiar with basic building science principles and have some experience with residential windows.
