Green Roofs and the Navy

I was recently at a local restaurant having lunch, alone, so I had to read something while I ate. The only thing available was The Flagship, a local Naval publication. I never served in the military but have a deep respect for those who do. I flipped the pages to find something I could at least understand, since most of this newspaper has to do with base news and command information. On the front page of section "B" of the Flagship, called "Front & Center" was an article about Naval Station Norfolk's Green roof project.

A green roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane.
Modern green roofs, which are made of a system of manufactured layers deliberately placed over roofs to support growing medium and vegetation, are a relatively new phenomenon. However, green roofs or sod roofs in Northern Scandinavia have been around for hundreds of years. Modern green roofs were developed in Germany in the 1960s, and have since spread to many countries. Today, it is estimated that about 10% of all German roofs have been “greened”.
Modern green roofs use succulents, or relatives of cacti as their main vegetation. Many sedums are used as they are drought and heat tolerant.
Benefits include longer roof lifespans, reduced storm water run-off, and energy savings as the building is better insulated. The Regional Legal service office at Naval Station Norfolk is scheduled to be completed this December.
It is awesome to see the government is focusing on things like this on our military installations. The day is coming that these will be commonplace, at least I hope so.....
