I think the government needs to set a clear goal, including what net-zero emission performance would look like for a whole bunch of different building sectors. Then they need to target any incentives, any financing and any policy towards meeting that goal. Right now we're saying that if you save energy, that's good, but we need to answer the question of how much energy and how much greenhouse gas emissions can be saved.
A big part of that is the government leading with enough public investment to catch attention and to say that the markets here are going to be transformed. This is an area where the private sector needs to pay attention. I don't think we've done that yet. It's very focused on one building at a time instead of saying that this is a big mission that you should be paying attention to.
