The UK has a much more moderate climate than most of the US. Compare London avg temps[1] with Boston[2] or Dallas[3].

The UK temperature averages are pretty close to LA, which is well known for being so moderate.

but thats the point right? aircon in dallas is the biggest energy sink in summer.

combined with the shorter days (compared to the UK) that means that insulation, solar gain control & thermal mass management is critical to reducing power usage.

Boston has double trouble, as in hot(ish) summers, high humidity, and cold-arsed winters.
