When we're looking at bases and wings and the infrastructure there, it's largely a question of investing to do energy refits. In some cases, it's to actually tear down old buildings and replace them with new. To date, Mr. Chair, we've seen about $145 million invested in military housing for green upgrades and around $50 million in energy performance itself. We've demolished some old buildings, as I mentioned.
The other thing I would flag is that at every base and wing we've put in an energy manager. They are responsible for identifying energy savings opportunities on bases. Some of them cover off multiple bases, but every one has one.
A final point that I should have mentioned earlier is that we do now have an example of our first net-zero building. It is in Gagetown, New Brunswick. We've had some New Brunswick mentions here today.
Those are the types of things we look at. It's no risk to operation. It's just a matter of time and money to either upgrade or replace the inefficient buildings we have on base and wing.
