A sort of dual comment.
I hear the cat's taken to head-butting Drswirly. It appears to be very placid.

I am with you on the chilled ceilings. What I want to know is when exactly architechts lost the ability to design natural airflow into a building?
Presumably this was at about the same time that they decided amphitheatres didn't work, and that big brick boxes would work soo much better, which was blatantly not the case.

What would you do about the condensation from the chilling?

Hmm, good question. In principle, making the air less excessively humid can only be good for the comfort level, but there is the irritating problem of avoiding it falling on people.

Hmm. How about a chilled ceiling in an eggbox sort of shape, with the aim of encouraging condensation to run down to the lowest points where there are cups to catch it and capillaries to pipe it off to somewhere out of the way? Would that work?
