The British seem oddly incompetent when it comes to getting air the right temperature. My office building, not even 30 years old, is routinely too hot or too cold. This despite an external temperature range that is not excessively broad over the course of a year. Tubes are notoriously stuffy. There are brand new buses on the route I take to work and they come with ventilation in the upper deck. Not air conditioning, just powered ventilation. It seems to make no difference whatsoever, except to be really loud. 78 decibels! For no benefit. This would be unacceptable in Germany, but maybe somebody here is proud of this great advancement in bus riding discomfort (there's also a curved rail on the stairs, which makes no sense, but I might save that rant for another post).
Fireplaces are done well here, but anything involving forced air ends up a bit of a crapshoot.
