HI. I'm looking for a database that could help me assess the average energy use of a home (per square foot, probably), separated by climate zone (HVAC, not USDA). I do audits all over the country and would like to find a source whereby I can assess easily if the home is above or below average for its location.
There is the great RECS database, but it separates by the four major geographic zones, not by climate zone. So, even if I could find a list of zip codes by climate zone, I could extrapolate what I need from that using the RECS.
Thanks in advance for any help anyone can provide!
I dont know of a database that you are referring to. I was always under the impression that each state had its own list like that, at least for roof coatings. I believe there was 13 temp zones for roof coatings in CA. Some coatings were not recommended for zones 1, 2, 3 because it got too cold and the coating would lose it's bond. Other coatings were not recommended for zones 8, 9 and 10 because it got too hot and the same thing could happen.
It has been several years since I have seen THAT list. Could this be the one you are thinking of?
You know those maps you can find for energy code climate zone specific reference. That's what I want except printed out - as a spreadsheet, best of all - by zip code, or county. Thanks anyway.
I posted the question on HEP's facebook page and Bill Spohn commented:
Thanks. That's the best source I've yet found, and maybe the best that's out there. Zip codes would be easier though.
