Mass timber building at Centennial College is taking shape
Ontario's first mass timber academic building is rapidly taking shape at Centennial College.
The college is collaborating with EllisDon, DIALOG and Smoke Architecture to build the province's first zero-carbon, mass timber higher-education building, with a design based on the Indigenous concept of "Two-eyed Seeing."
Forming a new gateway at Centennial's Progress Campus in Scarborough, the $105-million expansion to the A-Block campus building will embody the college's commitment to Truth and Reconciliation, Indigenous education and sustainable design when it opens in 2023.
"At Centennial, we view sustainability, inclusivity and Indigeneity as wholly interconnected and we wanted to create a learning space that demonstrates the importance of that tripartite relationship," said college President and CEO Dr. Craig Stephenson. "We're so incredibly excited to see our unique academic building rising quickly. Indeed, rapid construction is said to be one of the many benefits of working with wood."
Mass timber, which is composed of a mix of wood strips laminated together to form strong structural components, can substantially reduce greenhouse gas emissions in the building sector, cut wastage, pollution and costs associated with construction, and create a more aesthetically pleasing and healthy built environment. The components are predominantly Glulam columns and beams made of wood strips laminated lengthwise, and floor slabs of cross-laminated timber.
The six-storey addition will provide 150,000 square feet of academic programming space for School of Engineering Technology and Applied Science programs, flexible classrooms that support Indigenous ways of teaching and being, as well as support areas such as an engaging student touchdown area, along with collaborative spaces, administrative offices and food services.
"Indigenous perspectives inspired our core design narratives," says Eladia Smoke, Principal of Smoke Architecture. "We honour our host nations by reintroducing teachings from this territory, reinforcing relationships with the land and all our relations. Centennial College Indigenous staff and faculty worked with us to imbed these perspectives throughout, going beyond surface motifs to reach a deeper shared understanding that manifests in architectural space."
"The indigenous concept of 'Two-eyed Seeing' empowered our team to explore the ideas of zero carbon and mass timber through an Indigenous lens, as well as a Western lens," says Craig Applegath, Principal-in-Charge at DIALOG. "The two perspectives amplified each other; for example, the aluminum cladding was detailed with contemporary parametric software to replicate the way a fish's scales move over its body, shifting independently yet forming a single skin. It's incredibly functional yet also quite magical."
Environmental sustainability is a key attribute of Centennial's new building. Its zero-carbon emissions design, along with its ability to store thousands of tonnes of carbon in its sustainably harvested mass timber wood structure, sets an important precedent. The college is also pursuing an effective sustainability strategy to reduce energy consumption, aiming to achieve a minimum LEED Gold Standard, WELL certification and a Net Zero, or possibly Net Positive, building designation.
