I don't know. Having lived somewhere with a concrete driveway, and another place with a pavement/tar driveway (in the same area), I can definitely see the melting concern. It's not the thick piles of snow that cause problems, plows take care of that. It's the thin layers of slush, and the pools of water that refreeze into thin layers of ice. The difference between the almost straight white driveway and the black driveway was dramatic enough in my case that I had to resort to going outside and busting up the ice by hand with a piece of rebar, several days after snowstorms.
Now, I'm fairly certain that using reflective surfaces on roofs of buildings in warm climates and using absorbing surfaces on roofs of buildings in cool climates has been standard practice for... decades?
- eof 16y agoWell since this is for 'hot cities' the snow thing is pretty irrelevant.
- burgerbrain 16y agoHow is that defined? Even cities south of the mason-dixon line like DC can get some pretty crippling snowstorms, while being brutally hot during the summer. Reflective roofs make sense just about everywhere of course, but I really only see light roads being acceptable in places like Florida. And the glare would make it pretty unworkable in hot cities without decent cloud-cover.
