We are looking at all possible solutions, but one solution might be to place more emphasis on energy efficiency when renting housing. This could be achieved, in our opinion, by attributing energy rating to apartments. There are initiatives that target the owners of income generating apartment blocks. They are getting established, but not without difficulty. Programs really need to be quite creative in order to attract the interest of the owners of multiple income properties. At the same time, there have to be ways of ensuring any renovations to improve such properties do not systematically lead to rent hikes.
It is a really difficult situation to address, but I think that rental housing energy ratings would certainly be one way of improving the situation.
