I happen to be from Socal but we built this and the pics were shot in Northern New Mexico where my friend lives and where it is a bit more mild than Socal. That said it does get some hot days with a punishing sun during the summer (may top out around 100f/37c in a heat wave) and we were able to “test” the exterior this past summer in conditions pretty close to that. You can read about it on the website. Just scroll down to the section about the exterior metal: https://www.weshelterpeople.com/materials-and-costs https://www.weshelterpeople.com/materials-and-costs Important to point out that because of our location it would not need AC in the summer because evenings cool down adequately but if you wanted to use it anywhere in Socal that’s not directly adjacent to the beach you would “need” to have AC. I put the need in quotes because there are plenty of people in Socal who still live without AC, but I don’t think anyone would say those folks are comfortable doing so. It’s mostly a financial issue for anyone inland or as I said they live near the beach where a decent number of house and apartment rentals still don’t have AC.
