Gibson Island Clubhouse and Boathouse Renovations

The Gibson Island Clubhouse and Boathouse Renovations project replaced the existing clubhouse and renovated the existing cottages, located on Gibson Island, Maryland. The original two-story clubhouse was constructed in 1923 and was approximately 20,600 square feet. A separate two-story building housed eight cottage apartments and occupied about 4,200 square feet. The renovated clubhouse is now 29,300 square feet and the cottages were expanded to include a loft over the second-floor cottages totaling approximately 5,900 square feet.

The primary cooling source for the building is an outdoor air-cooled chiller. A chilled water pump circulates chilled water to air handling and fan coil units, while heating water is generated by a fuel oil boiler. The heating water pump circulates heating water to the air systems and miscellaneous heating equipment.

Multiple air handling units (AHUs) deliver conditioned air to the larger occupied spaces. Four-pipe fan coil units were provided for smaller occupied areas and are ceiling-mounted ducted units located within each occupied space. A central building automation system was also provided.

The clubhouse design included a dedicated 1,200A, 480Y/277V main service entrance and a separate 300A, 480V service entrance for a fire pump. The electrical service included power for two commercial kitchens with associated on-site refrigeration/freezer requirements. Also included was a 150kW generator to supply the building emergency and optional standby systems. Architectural lighting was provided throughout the building including approximately 66 different types of lighting fixtures. A state-of-the-art digital lighting control system was provided that allows multizone scene control for most spaces. A voice/alarm type fire alarm system was provided throughout the clubhouse and boathouse. The cottage design included a separate 1,000A, 208Y/120V service entrance. Power, lighting, and fire alarm system design was provided for the building systems and for all individual units.
