Thank you, Mr. Chair. I want to thank all the witnesses for being here and for sharing their expertise.
My first question is of a general nature.
Managers have to make decisions about certain buildings' energy efficiency. They have to decide whether to renovate a building completely or build a new one. It is sometimes difficult to make the right decision. They have to determine whether, over a period of 20, 25 or 30 years, it would be better to renovate or build something new.
Do you have any indicators that would help managers decide whether to build something new or renovate existing structures?
