RECS is good for this (in the U.S.). You can use the summary tables to slice by one or two parameters like region, vintage, size, fuel type, etc. You'll need to use the microdata if you need to slice more finely than that (not fast unless you have an established process for querying).
I happened to have this histogram handy. Looks like ~95% of SFD homes have Source EUI in the 40–200 kBtu/sf range.
For new/recent construction, I think it is always going to be faster to use BEopt defaults (i.e. Building America Benchmark/IECC 2009).
