-Historical Requirements: Building Enclosure: The building façade for the building is a brick veneer and curtain wall structure supported by a concrete frame. The addition to the Central Shared Unit consists of full height, exposed aluminum curtain wall system and open atrium. The roofing system is a protected roof membrane assembly consisting of a hot fluid-applied membrane covered by insulation and ballast. White color solar and light reflecting ballast complying with LEED requirements was used as the roof’s top layer. Sustainability Features: The Building One project was designed and constructed to meet at a minimum the Silver level for the U.S. Green Building Council's Leadership in Energy & Environmental Design (LEED) rating system, with the ultimate achievement of LEED Gold NC 2.0 certification in February 2010. Major credits to the LEED certification include re-use and environmental control. Mechanical: Single Outside AHU with Enthalpy wheel servicing Security Pavilion with 100% OA and meeting minimum OA requirements for other AHU’s. Two additional AHU’s servicing the open office areas with CV/VV boxes; 2-pipe fan coil units used in perimeter private offices. Instantaneous tank-less water heaters as well as plate & frame HX for domestic hot water. Administrative buildings of FDA’s campus are connected to Central Utility Plant, which houses absorption chiller, centrifugal chillers and ancillary plant equipment & distribution systems. Lighting/Electric: Daylighting and Occupancy controls provided with fluorescent lighting system in typical 2x4 layout.. Structure: Spread footings were used for the buildings foundation. To a large extent structure was only reinforced to withstand seismic loads; while replacement of choice beams and areas of slab were done. |
