ries of art form and core form, the building exhibits structural bravado, either by displaying structural steel directly or suggesting its form behind veils of cladding and finishes. The experience of the structure is central to the design: an oculus punctures the three stories of the building’s dramatic 16 M cantilever; intumescent-painted structural steel is revealed in the lobbies and display cases; and interior plasterboard walls sculpturally express underlying structural members.
Visual and physical interconnectivity are essential to the experience of the building. An aluminum louvre system unifies the upper three levers as a singular, sculptural volume. Developed especially for this project, the louver system forms a veil that choreographs views to campus, the surrounding community and the distant North Shore Mountains while maximizing useful natural light. The ‘Vortex Lounge’, a series of informal study spaces and an open stair wrapped around the three-level oculus, presents student activity as the face of the college. Circulation through the building is animated by views across multi-storey voids to different levels, and, wherever possible, into teaching spaces. Highly visible circulation elements and lounge spaces on mid-levels animate public spaces and mitigate the separation of stacked programs on separate floors, naturally promoting interaction among departments and encouraging the use of stairs over elevators.
TECHNICAL PRINCIPLES: The building’s strict programmatic requirements necessitated a footprint of a certain size, forcing the building to contort around the main entry roadway into the campus. Further complicating the design was the presence of a geothermal field immediately across the roadway, making it impossible to introduce a row of perimeter columns to support the upper floors. After extensive cost analysis, it was determined that a cantilevered solution would be the most efficient way to ameliorate the difficult site parameters. The 16.1 M cantilever extends the building over the entry roadway, essentially creating a site where none had existed before.
This ambitious structural solution was only achievable within the budgetary constraints of the project through the implementation of a highly ordered and efficient structural system. The building’s upper floors consist of a series of five trusses, three stories tall and 47.5 M long, providing the adequate back-span for the cantilever. Interior space planning was painstakingly coordinated around large diagonal braces and gusset plate connections. Additional structural challenges were involved due to the building’s location within a seismically active zone. Foundations along the ‘fulcrum’ line for example, were designed for roughly the equivalent load of a 40 storey tower.
Designed to LEED Gold standards, detailing focused on creating a thermally efficient building envelope. The upper three floors are clad in a cost-effective corrugated metal rain screen, supported by thermally broken facade clips and obscured by a shroud of extruded aluminum louvers. The ‘Sculpture Wall’ louver system provides solar shading while serving to visually unify the dramatically cantilevered upper floors into singular iconic volume. Louver density and orientations were carefully coordinated with window placements. The second storey of the building is clad with a Polycarbonate Wall Panel system filled with translucent insulation, providing diffuse daylighting while achieving exceptional thermal performance. High-albedo roofs were used to improve the building’s overall energy performance.
The mechanical system incorporates the Thermenex energy management system, an innovative locally designed energy recovery and transfer system in which waste heat is captured from building areas requiring cooling and selectively redistributed to mechanical systems requiring heat energy. Particularly significant given the high energy use of a lab building, the system dramatically reduces overall energy consumption, operating costs and greenhouse gas emissions. The building further reduces the need for mechanical systems by using stack effect in the six-storey lightwell for return air flow. The Thermenex system then captures the heat at the roof and redistributes it where needed.
