Energy Efficient Windows – Retrofit Opportunity?

October 11, 2015 at 9:01 pm 1 comment

I am an energy efficiency consultant out here in California and there has been a great deal of emphasis on  replacing older single pane windows with dual pane, usually vinyl models.  I many cases where a building is being remodeled the building owner has no choice but to install them in order to comply with the 2013 energy related code sections.  This is especially problematic if the building has some historic value to the city.  Now the Federal government in the form of Department of Energy’s Advanced Research Projects Agency (ARPA-E) is sponsoring research into methods to retrofit these older windows through its SHIELD program.


The full story is here on Green Building Elements ( The DOE website with detail on the program can be found here:
