Tips for energy saving at work
Does anyone have any hints, tips or advice for saving energy or identifying waste in your building?

Do any buildings have the equivalent of energy, water &/ or waste champions who can periodically ensure that unnecessary lights, etc. are turned off? Ideally a quick walk through around closing time might help to spot monitors, etc. that have been left on may at least reduce overnight energy waste.

I have asked our IT guys to force all computers to power down at 6pm. So many are left on overnight.

I assume that this would probably work in school settings because by 18h00 most everyone would have left. So, out of curiosity, how would this measure affect those who may be working on their machines at that time or would there be a way to over-ride this centralised switch off?

Apparently its not a centralised switch off. Each pc has this facility ( or will have with the addition of some software. At my school there is no one ever here after 1800 that requires a pc.

So theoretically individual users could set the time of the power down if it's not centrally controlled? Can you say anything more about the software that will be used for this? Thanks.

Depending on network set up, there is the option to do a centralised "switch off" over the network - such as described here for windows (can also be done on Apple or Linux machines)
However, this can be a bit intrusive for some (although good for a school situation potentially). For something a little less harsh - if you use Windows (like most people), there is the option to set the computer to hibernate, either after a set period of time, or on pressing the power button once (not holding it down, which will actually power it down). You go to Control panel -> Power Options -> select the power plan and click "Change plan settings" on the right. What comes next depends on which version of Windows - but somewhere there will be a "Hibernate after" option, which you can set to, say, 30 mins and/or a Power button action option - which you can set the power button to mean hibernate, rather than a physical power down. The screen shot for Windows 8 is below, for an example.
Hibernating is a very good alternative as the computer uses zero power in hibernated state, yet when the user comes back to the computer it returns to the state they left it within a few seconds. "Sleep" is a halfway house in Windows between simple screen saver on and Hibernate. You can compare the options here. (bit of a longer read)

It sounds very simple - but in our building, I think the biggest identified waste (and an easy one to fix, in theory) is having windows open while the heating is on. Heating takes the lion's share of energy for most buildings, so letting the heat blow out of the windows is a huge waste.
Other things that I like are automated light switch-off in unoccupied rooms (say 30 mins with no movement sensed on a PIR detector). Hibernating / switching off PCs where there are a lot is also good as discussed above.
