I'll just drive that home a little further.
In a recent renovation of the kind you've done in this building here, the BAS, or the building automation system, that would have been installed would be incredibly complex. Typically what happens when we commission the building and turn it over to the people who are actually operating it, there's often a bit of a slip, and the people who take it over may not know all of the features and ways that it can be maximized or optimized. A big part of what we advocate is to get our teams educated and make sure they understand everything they can do, so that at two o'clock in the morning, when no one's in this room, we drop the temperature by five degrees. It's very simple, common sense stuff, but it's a matter of making sure everyone knows how to engage in that.
