The US Postal Service has unveiled the largest green roof in New York City, which will help the facility reduce its energy usage by 30 percent and pollution runoff between 35 to 75 percent, depending on the season.
Environmental Leader reports that the green roof’s approximate 50-year lifespan is twice that of the roof it replaced (which was built in 1933). The green roof will, like its non-green predecessor, span 2.2 million square feet (nearly 2.5 acres). It will also support 200 pounds-per-square-foot of soil, vegetation, and other green roofing components. The roof nourishes a number of native plants and is furnished with certified-sustainable wood benches.
This notice reminded me of the green roof on the LDS convention center in Salt Lake City. I had the opportunity to spend an hour on the roof about 3 years ago. It was a beautful and quiet respite from the noise and heat of the city, not to mention the fabulous view. The roof was planted with vegetation native to the surrounding area. We met a gentleman who was enjoying the roof. He said that he often ate his lunch on the roof.
