Unfortunately, with regard to carbon, when the technical committees develop their building codes, they are not looking at carbon reduction or carbon-neutral construction. They are looking primarily at safety. How can we build this building so it's safe? It's not one of the objectives of the committees when they are looking at that. It is an added benefit. Obviously, if you are going to use a certain product over another, you may get an added benefit from carbon reduction.
To get to the first part of your question, there were impediments in the code originally. You used to be limited to four storeys. Anything over four storeys, you had to go to steel, concrete, or another non-combustible material. The committees' whole objective is to make this material agnostic. We're not giving one group an advantage over another. We're allowing the builders, the designers, the owners, and the government to choose which material they want to use. We've gone to six storeys, and the hope is that we will go to 12 storeys, and the next transition will be that it's material agnostic. We don't care what you build it out of as long as it meets these performance requirements.
