An innovative vertical campus, the Boston University Centerbbfor Computing & Data Sciences defines iconic and unique —and also sustainable.
The cantilevered and stepped massing plays into the building’s sustainability benefits, as it forms balconies and green roofs that allow occupants fresh air and stunning views of the city. The building’s interior design plays a sustainability role as well, with “irresistible staircases” that offer unique terraces in the atrium and breathtaking views of the city. The goal: invite people to walk up the stairs rather than take the elevator, promoting physical health and energy reductions. One of the largest components of the building’s sustainable construction are the geothermal bores, a system that is essential for BU’s Climate Action Plan goal of net zero emissions by 2040. BU’s goals also put the university ahead of Carbon Free Boston, the city’s pledge to be carbon neutral by 2050. Suffolk’s team drilled and installed a total of 31 bores, each 1,500 feet deep, which will harness the thermal capacity of the earth for heating and cooling and eliminate the need to connect the building to a gas line.
Due to space constraints on the urban site, the bores needed to go much deeper than a typical geothermal system — which is typically about 500 feet — to achieve the expected 300 tons of heating and cooling capacity for the 19-story building. At that depth, groundwater and rock formation plays a significant role in the verticality of the drilled borehole. Skillings & Sons, an experienced drilling subcontractor, controlled the verticality of the bores and kept all tolerances within five percent.
