Goodall Medical Building

WH Demmons performed the HVAC work on the Goodall Medical Building
Goodall Medical Building - Waterboro is a 24,000 square foot facility was built in 2007 and was designed for physicians practicing at Goodall Hospital. The suites consist of exam and procedure rooms, small labs, private doctor's offices with conference rooms and work areas for clinicians, nurses and secretarial staff.

Like the first Medical Office Building built for Goodall on their Sanford campus, this facility needed to offer patients convenient access to many services. Locating the Diagnostic Imaging and Laboratory suites between the Goodall Express walk-in clinic and the Orthopedic practice allowed for a two-way entrance from either department. A seamless patient visit experience resulted, thus meeting the owner's goals.

W.H. Demmons, Inc. teamed with Sheridan Corporation in the design and then in the build, handling all HVAC and Plumbing needs. The HVAC system basis for design includes customized VAV RTUs with double wall construction, added air filtration, an air flow station, an economizer with powered exhaust, and VFDs on the fan motors. These 2 RTUs serve a low to medium pressure duct system, using a continuous loop approach, which reduces both static pressure and energy consumption, and serves 40 VAV boxes with low temperature hot water coils. For the most part each medical room has a ducted RA system. Two high efficiency condensing boilers modulate to supply hot water with ambient reset (for improved efficiency), and are sized for run at part load for maximum efficiency. This hydronic system serves each VAV box, low temperature baseboard heat, and cabinet unit heaters. The controls are a DDC System, using WH Demmons logic.
