Hi,

I’ve been researching roof/wall assemblies for our new house, using this website and others. Throughout my research I assumed that our building location (south-central PA) was in a “mixed-humid” climate zone, based on looking at a state map. But then I found a detail listing climate zones by county and Surprise! Surprise! Apparently our county (Lancaster) is listed as “cold” climate zone.

Despite the map, I think our site should still be considered “mixed-humid”. What say you?

- Many of the surrounding counties are mixed-humid (see image with my notes)
- Note site location, only 9 miles north of MD border (red dot) 
- All MD counties (except one at west edge) are listed at mixed-humid

I’m trying to get detail drawing assemblies for the roof and wall appropriate to our climate zone (2x6 construction, ext. rigid foam). They’re available on-line but I would need to be correct on the climate zone.

BTW, source for climate zone info: http://www1.eere.energy.gov/buildings/building_america/

Thanks!
