In 15 seconds that's tough. That would take two hours.
It's like my colleague said. There is the issue of triple glass in the roof. Heat recovery is important to us. We will be able to play with sensors that will allow us to adjust the temperature based on where people are. There are other elements that we can use to detect movement and determine if an office is empty. At that point, the lighting will dim.
We are in the process of integrating all the codes and going beyond all the building codes or energy savings codes required of us.
I know I don't have a lot of time, but I could tell you one last thing. Among our architects and engineers, we have international engineers who have worked on similar roofing projects in other countries and that have been involved in other major projects. We are learning a lot from them. At the same time, we are making sure we respect every state-of-the-art environmental component and even go a little beyond that, as I said.
Being able to ultimately add 50% more space is also a savings. This may not be a sustainable savings. It's a savings that will enable us to eventually free up leases that we have in the city and bring certain groups back into our buildings.
In short, some savings will be environmental and others will eventually be purely operational ones that will take place within this new project.
Sorry for the short answer.
