The Portsmouth Public Library, New Hampshire's first municipal building to receive the prestigious LEED (Leadership in Energy and Environmental Design) (http://www.usgbc.org/leed) silver certification, has been recognized for its design and construction in the areas of energy conservation, recycling, lighting, and use of local materials. The library also contains other sustainable features such as low flow toilets, native drought resistant plants in the landscaping, and printers which release fumes out of the building, instead of in.
Despite being twice the size, electricity consumption was only up 50 percent from the former site. And even though the new building is 116 percent larger than the old facility and open more often, the amount of natural gas used to heat it decreased by 66.7 percent, saving the city $20,000 in the library's first year of operation. A self guided tour of the library which goes into greater detail about the sustainable features of the Portsmouth Public Library can be found here.
Drinking Water Treatment Plant
Located in Madbury NH, the water treatment plant has become the third building under the City of Portsmouth to be certified LEED silver. Its green features include solar hot water collectors, heat pumps, and "daylight harvesting" all of which reduce the buildings carbon footprint. The building itself is also sustainable as the material used to construct it is made of recycled materials. Lastly the building itself is highly energy efficient and exceeds the current energy code by 30%.
The City completed the construction of Fire Station 2 in the summer of 2010 at its new location, 3010 Lafayette Road. Some of the "green" features of this project include a super-insulated building envelope, high-efficiency natural gas boilers for heat and innovative site features to treat storm water. These features will result in significant annual operating cost savings and improved environmental conditions over a conventionally designed and built facility. The building was declared LEED Silver in May of 2011.
