US Schools are replacing blacktop with greenery to avoid the heat island effect (www.msn.com)

Today, the Los Angeles Unified School District has a goal of converting at least 30 percent of every schoolyard to green space, a years-long project that it expects to cost $3 billion. By its own estimate, about 475 schools do not meet that standard and, of them, more than 200 elementary schools have less than 10 percent green space. This analysis does not include school parking lots or truck delivery areas — paved surfaces that are likely to remain that way and raise the temperature around schools.

Webster, after years of waiting, is now on the list of schools to be renovated by the Trust for Public Land. The nonprofit will work with a class of third-graders and landscape architects for the next year to design a new schoolyard. Projects like this can take two to three years to complete, at a cost ranging from $400,000 to as much as $2.5 million, said Danielle Denk, who directs the organization’s schoolyard transformation work. In Philadelphia, most of the money for these projects comes from the water department, which is trying to make the city more capable of absorbing storm runoff.

While greenery is better than black top, there are studies that show metal roofs do not retain heat at night and are virtually care free.

I've never heard of these things. What about the sunlight reflection's glare, and how would this be better than conventional roofs or solar panel roofs?

That doesn't address what I said about glare, and well, I had the expectation that "blacktop" was low-budget playgrounds, not literally black tops. And why metal when you can have a tile roof or a solar panel roof?

Tile is stone and retains heat.

But it's better than anything made from petroleum
