The newly constructed $74M Frederick E. Berry Library has a hybrid heating and cooling system that was designed to combine conventional HVAC technologies with the efficiency of geothermal energy. SAK Environmental was retained to assist the project team with design and construction of the closed-loop geothermal well field to be connected to the library’s hybrid HVAC system.
The geothermal system consisted of forty-eight (48) 500-feet deep closed-loop wells that provide 120 tons of cooling capacity and 1000 MBH of heating capacity, allowing Salem State University to become more energy independent.
Throughout the project, SAK provided geologic and engineering expertise in well design and construction, on-site construction inspection, compliance with contract documents, and geologic condition assessment. SAK completed a technical peer review of the geothermal well design plans and specifications prepared by the design team, and provided design modifications for the well field layout and configuration of the horizontal piping. SAK’s construction monitoring ensured proper drilling and well construction, which is crucial to achieving maximum performance from the geothermal wells. Construction administration services included density analysis of borehole rock samples, review of contractor submittals, and participation in weekly project meetings.
The new geothermal system offers an efficient heating and cooling option for the new 122,000 sq. ft. space, and helps meet DCAMM’s (the state's building authority) goal of maximizing energy efficiency in all State facilities. Along with other sustainable features, geothermal heating and cooling will allow the building to earn LEED Silver certification through USGBC’s Leadership in Energy and Environmental Design Program.
