I was reading up on 'cooling paint' yesterday (this article was pretty good and understandable, https://www.sri.com/fcd_technology/self-cooling-paint-a-passive-radiative-cooling-solution/ ). I also saw a thumbnail of a video claiming that you can make your own "Thermal infrared cooling paint" yourself at home - I felt quite dubious about that but didn't have 40 minutes to spare to check it out.

A quote from the linked article: Self-Cooling Paint is a passive radiative cooling solution – without requiring any power or electricity, it can cool down any surface up to 5-8 ºC ( 8-12ºF) below ambient air temperature, and 10-15 ºC (18-25 ºF) below an uncoated surface based on internal tests*. Achieving sub-ambient temperature is significant, and has been accomplished by engineering a coating that combines high solar reflectance with high infrared emittance in the sky transparency window.

This is so interesting. Cooling a surface below ambient air temp? Just amazing. I would love to see what that would do to my attic space, for example, which gets extremely hot in summer. My only puzzlement is - would that also be in effect in winter? If so, then my 'cooling roof' would turn into quite a drawback. Unfortunately, I don't understand the underlying science well enough to draw a conclusion here. It may be that the paint is primarily of use in climates where there is little or no cold weather, and heat is the biggest concern.
