PARIS, France — In my role, I pick up on the varying styles of buildings, and the touches of detail which point to a time in history. But what I also notice is how they were built for the climates they were intended for, and how resilient they might be to the reality of a changing climate. I am asked… as climate change rhetoric becomes mainstream, what role our historic buildings have in our fight to tackle it. There is a lot that goes into creating a building — especially when we think about its full life cycle — the materials, construction, electricity and fuel needed to make it functional, not to mention the maintenance. …As Paris prepares to host the Olympics this summer, climate eyes will be on organisers for how sustainable this historic event can be, especially when considering the multitude of its construction and increasing efficiency of modern buildings.
