Re: 'be at 20C by 06:30' @AC
Sensing whether a space is in use and saving energy accordingly is not always straightforward. Many years ago, my battalion was training for a deployment. This involved lectures to 600 people, and the only sufficiently large space was the gym.
Some bright spark had improved the energy efficiency of the gym by installing movement-controlled lighting - after all, people are always moving in a gym, aren't they?
Thankfully the Regimental Sergeant-Major had a solution to the problem of sudden darkness 5 minutes into each lecture: instead of the usual barracks-cleaning and other punishment details, the day's defaulters were lined up at the back of the gym to do PT and keep the lights on.
