|The new 208,000 gross square foot NOAA Satellite Operations Facility (NSOF) consists of 140,000 square feet of adaptable open office space, a 60,000 sf satellite control and operation center, and underground parking for 286 cars. The facility contains the National Environmental Satellite, Data, and Information Services, which manages the operational Earth-observing satellite systems of the United States. The architectural and engineering design for the complex incorporates many sustainability features. The facility is housed largely under one of the largest green roofs in the country, totaling 146,000 sf.|
The office space is located partially underground and built into the existing slope on the site. This lowers thermal gain to the building by utilizing the insulating properties of the earth. Light wells, skylights, and court yards are distributed throughout the floor plan to ensure occupants have access to natural lighting. High performance filtration, UV lights are used to minimize airborne contaminants from entering air stream. Materials were selected to minimize off-gassing of VOCs. Full commissioning of the building systems was required in order to ensure correct operation and inter-system working. This minimizes problems during the move-in period from non-functioning systems while maximizing system efficiency (OFEE Issue 42).
The landscaped roof helped the NSOF, a 60,000 square foot building with 549 employees, receive the LEED Gold rating in early November 2007. "Only 20% of the site becomes impervious, elminating the need for a water detention pond or increased stormwater piping, while saving thousands of dollars," (GSA website, see below).
|Paul Pegnato, NSOF project manager, says "The building is very unique. The architect had this vision of a sloping landscape. So when you start on the north side and are walking across the landscape, you're walking across the roof without even knowing it." (ItWorldCanada Green IT, 12.07)|
