Mayor Frank Guinta; UNH Cooperative Extension to unveil, give tours of city's first Green Roof

MANCHESTER (November 5, 2007) – Mayor Frank Guinta, along with members of the University of New Hampshire Cooperative Extension and other city and state officials, will be on hand to officially unveil and to give tours of the green roof installed on top of City Hall. The event will begin at 1:00 p.m., on Friday, November 9, 2007, at One City Hall Plaza, Manchester. Light refreshments will be served and there will be a ribbon-cutting ceremony.

The green roof, which did not use any taxpayer funds, is the first of its kind in Manchester and the first on a governmental building in New Hampshire.

“This project is truly a precedent-setting one in New Hampshire, and I am proud that Manchester is on the forefront of this type of environmental progress,” Mayor Guinta said. “The benefits of a green roof are numerous, but first and foremost, it shows the commitment that Manchester has made to the environment, the economic well-being of city taxpayers and the overall quality of life that our residents demand and expect.”

Some of the benefits of green roof technology include:

  • Absorption of up to 95 percent of an average rainfall. This prevents flow-off onto pavement and into storm drains, which carries into it pollutants such as gasoline, oil, antifreeze, and trash;
  • Reduces the energy needed to heat and cool the building below ;
  • Extends the life of the original roof;
  • Filters air pollutants and improves air quality;
  • Absorbs noise;
  • Reduces the risk of flooding and overflowing sewers; and
  • Provides habitat for butterflies and other pollinators
