I would say generally that we observed that they actually do label homes in Europe in some of the economies like the U.K. and Germany. Buildings are labelled at the point of sale. This has a significant impact on the energy improvements made to homes and the standard they are built to.
We also see that on a building scale. Energy benchmarking and disclosure have been adopted by a number of jurisdictions in North America. Cities like New York, Chicago, Seattle, San Francisco and so on have adopted it on a mandatory scale for building owners who have to report on buildings over a certain size.
As you know, the Ontario government has adopted it as well, provincially, starting I think at 250,000 square feet and stepping it down every year—to 100,000 square feet, and I think the lowest level is 50,000, if I recall. We believe that mandatory benchmarking disclosure programs are really important to move the industry forward. I'm saying this because the large buildings, the large commercial owners and so on, are already doing it, but in order to bring about change, we need the other 90% of the buildings. They need to be engaged in a standard performance and disclose their performance, and then that will help them and policy-makers to target their investments to make improvements to the energy-efficiency area.
