In September 2014, Convent of the Sacred Heart celebrated the opening of its Athletics & Wellness Center, a one of a kind facility among Manhattan’s independent schools. The 53,000 square foot center features an extensive program within a tight footprint, on the site of a former parking garage that was partially reused for this project. Located at the opposite end of East 91st Street from the school’s main academic building, the historic Otto Kahn Mansion, the new structure possesses a muscular but graceful street presence with masonry-driven solidity, underlying classical proportions, and unexpected combinations of brick recesses, corbeling, and wall thickness. The center includes a six-lane swimming pool, an NCAA regulation-sized volleyball/basketball court that is structurally supported by a unique truss system, a dance studio, a cardio and weight room, multi-purpose rooms, locker rooms, classroom space, and a grand daylight-filled stairwell that encourages activity beyond the bounds of sports. A host of sustainable design strategies support the operations of the LEED Gold registered center, as well as the health and comfort of its users. Solatube skylights, a solar hot water system, a cooling tower supplied through rooftop retention tanks, and a pool dehumidification heat recovery system all contribute to thermal comfort while minimizing nonrenewable resources consumption. Whenever possible, building materials were composed of 100% recycled content, and the team diverted over 95% of construction debris from landfills. To support an intensive IAQ management plan, low-emitting materials were used, and the team conducted a robust pre-occupancy flush out of airborne toxins prior to the facility’s opening. In support of the client’s educational mission, the center incorporates several opportunities for self-guided learning. For example, easy access to sustainable systems like the rooftop array of evacuated tube collectors will open students’ eyes to the sources of the building’s energy.
