Again, it's a really good question.
I'm not an expert in wood buildings, but I've been around enough of them and seen enough of them to have an opinion on them. I think that in terms of fire ratings, these mass timber buildings actually rate quite well. They rate as well as steel and concrete buildings. It gives enough time for people to leave the building, because the wood is this mass timber. This is not stick frame. Mass timber will actually char on the outside, which prevents the fire from rapidly burning the timber. That's one of the considerations. It does give enough time to get out of the building, as compared to concrete buildings. That's my understanding.
I think there's a significant market for buildings that are eight, nine, or 10 storeys that can be built with those systems. That's where the opportunity is. They don't need to be 18 storeys. I think you have to fight public perception, first of all, but also in terms of codes and so on, I think there might be some issues there. There's plenty of market. I've seen many of these structures that are eight, nine, or 10 storeys high. They can be built very rapidly, and prefabricated. You can pour the elevator shaft and you can put in one storey per day. Sometimes you can build them very quickly. You still use concrete in the floors to provide some stability, and so on. These are not simply wood buildings; there's a combination, but wood is the predominant material.
I would say that's where the market is. We have a lot of demand and need in Canada to build these mass timber buildings of eight to 10 storeys, particularly in urban infill, because it goes very quickly if we choose specific technologies.
