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!
Well, sort of... even Washington State has another chart that breaks down the climate zones into smaller chunks. That's because states often recognize a large difference between the north & south, or east portions of their state. The IECC and general US climate maps have a coarser resolution.
Incidently, the link works for other states - if you use the drop down box...
Here is the California Climate Zones by Zip Codes http://www.energy.ca.gov/maps/renewable/building_climate_zones.html .
