I never have been to NYC, so I wouldn't know. I just see the homeless here in Nashville Tn. and some might be just that desperate.

OK, so in summary, I'm wrong.
Wal-Mart just published the results of their study comparing white & green roofs, using stores where the two techniques were tested side-by-side, and green roofs were the clear winner. Given that Wal-Mart currently uses white roofs on their new projects, and just how huge Wal-Mart is, this is a potentially very big deal.

Applicable to the discussion about rainwater..."Of the 100 precipitation events studied, the green roofs retained an average of 74% (80%-90% of small storms and 60% of the largest storms). Peak runoff from the green roof was delayed 1.25 - 3.25 hours from the rainfall peak, and the rate was 50% - 85% lower than the precipitation peak rate (average 65%)."
Edit: These are extensive green roofs, ie sedums and grasses. Designed for low-weight, high retention, low maintenance. An intensive green roof, that might host gardens & etc, is more work.

Very interesting. I'm surprised Wal-Mart would have done this study. They don't seem like a company that would use green tech.

If it's cheaper, why not? They're just following the money. White roofs are cheaper than black roofs. Green roofs are cheaper than white roofs.

True, and if it was any other company, I wouldn't be surprised. However, I would think that going with a green roof would change the image that is put off by Wal-Mart. A green roof is something that you would expect from some store like Whole Foods, which has shoppers that aren't constantly looking for cheap stuff.

I think people are a little more flexible than that; if Wal-Mart does green roofs, they don't assume that the tree-huggers are good, they assume that wal-mart has figured out some advantage to it. Even if it was true, it's not something they need to advertise. Extensive roof systems are sedums (succulents) and grasses, low plants usually not more than a foot high. It's just not obvious unless you're looking down on the roof.

Oh, I disagree, especially considering the typical Wal-Mart shopper.
I'm pretty sure that news outlets would be glad to advertise for Wal-Mart regarding the green roofs. This would be especially true in some of the smaller towns where there is a Wal-Mart. A couple of years ago, a friend told me about having gone to visit some family in South Carolina, if I remember correctly, in some small town. He was hanging out with his cousins on a Saturday night, and he wanted to go out. They told him to get dressed, and they all got dressed up as if they were going to a club. He figured they would go to a club somewhere. Instead they took him to a Wal-Mart because that was the place to go to on a Saturday night. I told that story to one of my GF's friend's wife, and her response was "Hey, that's like my town." She came from some place in Louisiana. Any way, the point is that in those towns, if there is a significant change in the place that everyone goes to, it's going to make the news.
