We can give you a really quick example. A three-storey provincial office building in rural Manitoba with about 250 civil servants on four levels implemented a digital control project there in 2006 and had savings of $30,000 in electricity. Obviously the building wasn't being operated properly.
The other big lesson is that a lot of buildings aren't commissioned when they're built. That building is of 1970s vintage, and a lot of our portfolios are.
