This week, the first building added in 60 years to New England Conservatory’s (NEC) historic Boston campus will open. The new Student Life and Performance Center (SLPC) is a ten-story mixed-use structure offering over 250 residential units, along with space for dining and music-related preparatory work with a focus on collaborative research and experimentation. Ann Beha Architects (ABA) and Gensler designed and realized the building as a collaborative and integrated team—the two firms’ fourth collaboration. Both the design team and the Conservatory wanted the project to have a unique identity and distinctive expression. Sited in a historic context, the design team sought a traditional cladding material that expressed craft, sustainability, and durability. They prioritized a “handmade” aesthetic, ruling out the machine-like qualities of colored concrete panels, composite materials, and costly glass curtain wall systems. The exterior envelope ultimately featured a refined composition of variegated terra-cotta tiles, applied in mixed patterns, with broad glass expanses at street levels, and stainless steel screen cladding. Offset operable windows animate the upper floors, and north-facing open lounges offer expansive views of Boston. ABA turned to Ludowici, a terra-cotta manufacturer known for 19th century historic tile roof renovations. Its subsidiary, Terreal North America, engaged with the architecture team during the design process and produced samples for full-scale on-site studio mock-ups. The mock-ups became an integral part of the design process due to the custom nature of the tiles, their assembly system, and finish options, and helped to facilitate collaboration between the design team, client, and city oversight groups. “The idea of implementing this innovative facade was exciting for the Conservancy,” said Ann Beha, owner of ABA. “The fact that you couldn’t just go see something like this elsewhere meant that mockups were an essential part of the process.” The architecture team worked closely with Terreal North America to develop a gradient range of tiles that animate and anchor the building. Deep tones located at the base of the tower give way to lighter hues as the height increases. The challenge became how to achieve this effect within technical and budgetary constraints. The team worked with three glazes, each with a wide variety of coloration. Percentages of these mixes were then varied. The architects developed a “paint by number” style document to specify the final distribution across the facade, which the installer referenced on site. The unique color blends were created by a proprietary glazing process designed by Ludowici, referred to as their “Impressionist Series.” The process features a random multi-spray matte glaze application that creates a unique finish patterning on every tile. The colors chosen included Terra Cotta, Dark Terra Cotta, and a custom color. Distinguished from and responding to the terra-cotta tile, the facade of the performance center is marked by a 40-foot-tall metal screen mounted in front of the orchestra rehearsal room’s double-height facade. The installed Centria metal panels have a ridged profile that improves their structural capacity, and vertical shadow lines. The material clads a radiused steel frame, reading as a vertical curtain that peels away from the building envelope to reveal the school's performance spaces.AN spoke to ABA about the composition and detailing of the facade, which is organized around variable window spacing that relates to the width of student dormitories. “We liked the idea of an inscribed horizontal line that acts visually as a datum that all of these shifting panels could relate to,” said Steve Gerrard, principal at ABA. “It becomes especially important where the windows increase in their frequency. The line is an important compositional tool to relate to each of the floors.” Beyond compositional refinement, the envelope's energy performance allowed for a reduction in HVAC system sizing. Beha said the durability and aesthetic quality of the tile rainscreen cladding was particularly successful. “We see concrete panel structures built all over Boston, and they seem to lose their color, and their quality, so fast. This will not.” Beha concluded, “For me, the painterly aspects of the result are consistent with the issue of urban identity and urban contribution. We wanted a facade worth looking at and considering, and one that brought NEC distinction, dissimilar from others, and enduring, simple, distinguished, in its own way.” ABA said the facade composition reflects the New England Conservatory’s own ambitions: creative, contemporary exploration that combines tradition and innovation. The project was dedicated in a ceremony on September 14th, 2017, and will open to the public the following week with a full day of programming involving performances and talks.
