Thoughts on AC
Air conditioning an office for one extra hour a day uses enough energy in a month to power a TV for over a year. (The Carbon Trust)
Air conditioned buildings use roughly twice as much energy as naturally ventilated ones. (Royal Institute of British Architects).
If we can't live without ACs, at least let's turn them down (I am usually freezing in any AC-ed building) and turn them off at night (open your windows).
