Since DEWA introduced the "slab tariff" system, so the more you use the more you pay per unit, I would imagine Emirates DEWA bills have gone through the roof and I wouldn't be surprised if they decided to do something about it. It is an easy target for money saving and they can dress it up as being a green thing.
The fact remains it is almost criminal the way some people (but by no means all) in company accommodation waste water and electricity. It is entirely up to you if you want to leave your a/c on all day and all night, or hose down the drive every day, or turn your back garden into a swamp, but you should be prepared to pay for it.
