When the University of Massachusetts at Amherst broke ground for its new Life Science Laboratory in the summer of 2010, it launched the construction of a $ 156.5 million facility equipped for cutting-edge scientific research, designed to bring together researchers from different fields to work on initiatives ranging from developing biofuels and clean energy to drug design. Phase 1 of the building project, completed in March 2013, houses large, flexible laboratory space, and features energy-efficient building systems and a high performance envelope.
Incorporating sustainable design into the 310,000 square foot Phase 1 facility was key to the building’s creation. As a result, the LSL includes a variety of systems that will qualify it for LEED Silver certification—perhaps even LEED Gold. One system is the Schöck Isokorb Type S (for steel-to-steel connections), a load-bearing and thermal insulating connection. To meet the project’s energy efficiency goals, more than 248 Isokorb elements were installed at structural steel beam connections, supporting the glazed canopy covering the 310-foot walkway along the building’s facade. Isokorb provides a structural thermal break connection at the canopy which helps retain energy in the building while also preventing condensation, and mold which could cause damage to the interior finishes.
According to project architect Kevin Triplett, of Wilson Architects, building canopies are typically supported on beams that cantilever out from the interior of a building. During winter months, these beams are exposed to cold weather and transfer cold temperatures into the building. “To address this problem, we consulted an exterior envelope specialist, who recommended Isokorb,” Triplett says. “He said it was the only solution and identified Schöck as the pioneer in this area.”
Schöck invented the first thermal break technology for use in structural building components such as concrete and steel. Currently utilized at many sustainable projects in the U.S., Schöck Isokorb Type S is specifically designed for use in steel construction. It can withstand extremely high loads and bending and shear force. Its stainless steel components (stainless steel allows just a quarter as much heat flow as standard steel re-bar), working in tandem with 3-inch rigid polystyrene foam insulation, ensure that no condensation can occur and thermal bridging is kept to a minimum.
“We are required to meet LEED Silver with this project,” says Triplett, with the many sustainable design systems installed, “we are on track for LEED Gold.” The architectural team performed ASHRAE energy modeling on the project and as a result, “we expect to save $300,000 annually in energy costs, and Isokorb is contributing substantially to this savings,” he added. In addition to Isokorb, other energy efficient elements in the building include a heat recovery plant, continuous air monitoring, radiant floor heating, and energy metering systems.
“We would by all means use Isokorb on the next phase of the project,” he added. “We were very impressed with Schöck’s products and the responsiveness of their staff—they responded quickly to our questions and visited the job site to make sure that the system was installed correctly.”
The LSL occupies a site at the east edge of the school’s core campus, in a beautiful natural setting. When complete, it will link with adjacent buildings, specifically the Integrated Sciences Building, and to the pedestrian and infrastructure network in a way that creates both “civic” space and enhances accessibility. It will be home to 64 faculty members and their research groups and will, according to Chancellor Robert C. Holub, “allow current research to flourish and open new avenues for scientific advances by our faculty and students.”
