I am completly opposed to Air-conditions propagandized as a solution to climate change. What is the wright approach to combating this state of temporary relief except from old-fashioned fans? Don’t get me wrong. They do the job for me. I am reffering to finding a solution for people more with health issues or large facilities that are in need of something more drastic.
You might want to look at metal roofing. White helps and makes sense from a visual standpoint where the base material can only be dyed/painted and not changed, but even painted metal reflects infrared better, which is where the heating energy really exists.
Insulated attics make roof material irrelevant. Heat comes in from walls.
Unnecessarily reductive. It’s both the ceilings and walls. There is no single solution. We also have no idea of they have an attic or vaulted ceilings. An attic full of hot air is a heat bank that will radiate into the living space all night. All insulation will do is slow the transfer. Really good attic floor insulation will help retain heat in the attic, so you still want to improve attic ventilation. But, if you reduce the amount of heat going into the attic in the first place, you reduce how much insulation and ventilation you need to reach a certain cost/benefit ratio. It’s usually more feasible to do half a job addressing each than it is to make just one variable perfect. So, when it comes to replacing a roof covering that needs replacing anyway, doesn’t it make sense to do that as best as feasible?
Tour a home with an infrared thermometer camera in summer. I promise you, the ceiling is warm, too. You just don’t hang out 3 meters up.
A white tin roof is the plan.
Eeeexcellent, I’m excited for you.
@XeroxCool @nocturne There are special nano-materials they have that blocks all IR heat from entering the building. We shall see how this scales.
I’ve seen some science channels posting these over the last few years, making coatings that emit radiation in the “atmospheric window” I think it’s called, but have not yet seen proper products on the market. I could be out of date though. Still, I’d question durability, but I suppose it’d be at least no worse than normal materials, right?
