This is a Garage Green Roofs in Mount Baker. A truly new, designed by the architects of Puget Sound to overcome the problem of pollution is the complete installation of green roofs on the houses of Puget Sound to help restore its natural beauty. These roofs retain rainwater and prevent runoff by impressive margins, saving rainwater to flow into the sewers.
In addition to ease runoff, green roofs help mitigate the urban heat island effect and provide ceiling insulation, which reduces energy consumption and emissions of green house gases associated emissions. They can also provide wildlife habitat. And surely seem heckuva lot nicer than a white roof.
The only question that remains is: why are still so rare in the Puget Sound? Of course, we have a handful or two, especially in municipal buildings, but nothing compared to what is done in Europe. And of course, the reason for this disparity is reduced to ideology: European companies are much more inclined to exercise the power of government in the cause of the common good. In other words, significantly regulate and subsidize green roofs. (This is also why Germany is the world’s largest consumer of PV.)

Building rating systems such as LEED and the City of Seattle Green Factor new code are designed to encourage green roofs. But since the initial costs are so large – about twice a conventional roof – most private developers remained lukewarm. The problem is simple: the free market is a little shaky when it comes to the future and the common good. The solution is simple: government incentives.
While flat roofs ubiquitous highly urbanized areas are the easiest targets for green roofs, there is great potential in the sequence of roof impervious to the great square of Seattle single-family zones, as in the two photos attached. But so far, these projects are extremely rare. If readers know of other small-scale projects of green roofs, consider him a good excuse to leave a comment.
