Yes, absolutely. Thank you.
It has been around for a number of years. As I said, about a third of your buildings have already been done, and there's a great opportunity to use it more. It's a matter of using the funding available from the private sector and having them take the risk that the project is going to come in technically and financially.
There were earlier questions about evaluation. One of the key parts of any energy performance contract is that it's a very detailed evaluation measurement and verification protocol, using an international standard to make sure that everyone agrees on how we're going to measure. This is why it's called a guaranteed performance contract—because it's guaranteed and the performance is guaranteed.
Especially when it's a multiple project where there are mechanical, electrical, and different features going on, it's really important to bring those in and have a complete, comprehensive turnkey project done. Again, as I said, the advantage of having one company involved is that if there's ever any problem with it, you know who to go to.
I was in the States recently with one of their governments. It's a very active program in the U.S. right now, and it has been for a few years. They said that it's often the energy performance contractors who will go to the government and say that they've noticed a problem with a building and they're going to go in and fix it. That is before the government has even noticed a problem, because it's the company that is at risk, so it's up to their incentive to identify any problems and rectify them as soon as possible.
