We provided civil, structural, electrical, HVAC and plumbing engineering services for the new 36,000 square foot facility. The entire building, including the mechanical systems, were designed to LEED requirements with the objective of achieving a Gold rating.
The plumbing and HVAC design involved the installation of new indoor air handlers equipped with chilled water and hot water coils to provide heating, ventilating and air-conditioning to the facility. The design included variable air volume boxes with hot water reheat to provide better zone temperature control as well as variable speed drives on the air handler fans to improve energy efficiency. Hydronic radiant floor heating was also incorporated into the design to heat the large atrium spaces with expanded glass exposures. Finally, a fully automated building management system was specified to optimize time of day scheduling for the HVAC system.
Chilled water and high temperature hot water were provided from a central heating and cooling plant located on the Riverhead Campus. We provided the design for a local heat exchanger station to generate heating hot water from the high temperature system. As part of the project, we also designed the modifications to the existing buried chilled water and high temperature hot water distribution piping. Existing piping had to be removed from the site to allow for construction of the new building. The design included the installation of new manholes and piping as necessary to feed the proposed new building and provide a connection point for future buildings on the campus. We worked closely with the architect and the campus facility personnel in relocating and designing the modifications to the existing underground utilities.
