There is also the possibility of using colored “cool paints”. They look the same at the human eye, but the spectrum is cut below the infrared, reducing the heat absorbed

Amy Kwan had studied in detail roof-top gardening and naturally insulating homes against weather. Very interesting and thought-provoking.

That’s pretty interesting… but I am confused about how a white roof “reduces smog” and a black roof “keeps in smog”? Unless the graphic is suggesting that, since black roofs are hotter and people inside these buildings use more A/C, that the black roof indirectly contributes to smog… but when I first read it, it seemed to imply a “direct link” between black roofs and smog, which doesn’t make much sense to me.

Wow great tip! Awesome way to reduce your home’s carbon footprint and go sustainable. I hope more cities will follow in NYC’s path and take the same initiative for white rooftops.

The electric utility FPL pays the entire cost of white sealing businesses roofs. I is supposed to save 40% of energy costs.

But what about in the winter time? The black roof will absorb much needed sunlight to provide some warmth in the building.

if you offset the added cost of a white roof during winter months…
