That would be consistent with what we are thinking as well. Setting energy intensity targets for buildings is very important. With the new database that NRCan is launching, or with Energy Star, we get a better understanding of what the energy use will be.
But there are also organizations such as ours, or engineering firms, that increasingly keep numbers on where buildings should actually be. There's obviously a range of performance that you will see, which we saw in our benchmarking programs. Sometimes the ratio is 1:6 for the same building type, depending on age or region or operations—there are all kinds of factors playing into it. But there's increasingly data that would allow you to do this.
What it will do for you is that it will really focus the efforts on how you can get to that target, rather than leaving it more open.
However, I think it's really important too not to let the carbon slip from view, because energy use is related to costs, and carbon is related to environmental impact. The challenge is now to reuse carbon and save money at the same time.
