Has anyone here ever owned a white building?
They’re very hard to keep clean, especially in urban environments, which soak up most of the power used for cooling and where this product would be most beneficial.
How easy is this stuff to clean? Is it easily damaged by pressure washing? What kind of cleaners are needed for this to function reliably? Are those cleaners safe for the environment?
You’re right: it’s probably not practical to paint a building with the stuff. Nighthawkinlight briefly comments on this. I believe the idea is to use it on passive radiator panels to sink heat from a pumped coolant fluid. That way you can strategically place panels (e.g. on the roof) and control them, just like solar heating panels.
