What do you think of the .32 U-factor requirement being considered for the Northernmost zone in the 2009 Energy Star criteria?

Following up on a Department of Energy update on plans to make criteria to qualify for an Energy Star window label more stringent, last week we asked what you thought of one of the most stringent numbers under consideration—a U-factor of .30 for the Northernmost climate zone. Read Page 2 of the Talk and you’ll see the response was pretty overwhelming.

DOE actually said it’s considering a U-factor requirement of between .30 to .32 for this zone. We found out most of you think .30 is too stringent. What about .32? That’s our poll question this week and I’ll add one note—it’s been suggested to me that even .32 could be problematic if DOE also establishes an SHGC requirement, possibly as low as .35, for that same region.

I want to assure all you readers in warmer climes that we haven’t forgotten you. We’ll be asking about the numbers that impact you most too in the coming weeks. Of course, you don’t have to wait for a poll. If you have particular concerns about the Energy Star criteria in the Sunbelt, I’d like to hear from you. I encourage everyone to email me with your feedback on changes to Energy Star.
