Gallery: USPS Energy Retrofits Saved $400 Million since 2007


Many national businesses produce sizeable carbon footprints but very few actually do anything about it. However, thanks to new guidelines from the Department of Energy, the United States Postal Service has rolled out a plan to make itself one of the greenest delivery companies in the country by cutting its energy usage.

    The project very nicely demonstrates how bad existing and many new buildings in the US are. 4 inch more of insulation would have at least 100% better insulations value that any extensive green roofs and it would cost only 10% of a green roof.
    Insulation works year around and don\\\’t decrease the value in winter like green roofs do. Thicker insulation (min. r-65 is required in Europe – NYC r-38 ceiling and much less walls) all around the building (not only on the roof which is typically only 30% of the building surface) could save more than the double of what they are currently doing.
    Everything combined with a green roof would get close to meet European requirements from 1990 in most big cities – to get to the level of current European requirements it takes much more.
    Nevertheless they are starting to do something and as usual the press releases are bigger than the benefit for the environment.
    This is my own European green roof expert perspective.
