Green roof built for NY Post Office
The U.S. Postal Service recently unveiled an 11,300-square-foot green roof installation in upstate New York, its second green roof to date, reported Environmental Leader.
The green roof construction consisted of verifying the soundness to support extra weight, fitting the roof with a new membrane, and installing layers of drainage sheet, mat, separation fabric, indigenous vegetation and a wind blanket.
The roof is expected to last roughly 50 years, and it will reduce the amount of contaminants in storm water runoff flowing into the municipal water system. The USPS said the roof should “help the post office reduce energy use and associated greenhouse gas emissions.”
While the USPS sustainability report released on June 25 does show that the organization's carbon emissions rose 0.7 percent from 2010 to 2011 despite a decline in revenue, USPS is making other strides toward sustainability, with a target goal of cutting energy use by 30 percent by 2015. The green roof installation is part of the USPS’s “greener facilities strategy,” which incorporates the use of environmentally friendly building components and renewable materials, the installation of energy efficient lighting and HVAC systems, and the use of low-water fixtures in facilities, with some photovoltaic systems incorporation.
