Diamond and Schmitt Architects leads waterfront renewal

Diamond Schmitt Architects as Architects

Corus Quay is the first new building of Toronto’s waterfront redevelopment. The eight-storey glass-clad building completed in September 2010 is designed with restraint, minimalism and simplicity to showcase the broadcast activities of Corus Entertainment within. Embracing its waterfront context on a remediated brownfield site and adjacent to Sugar Beach and a promenade, Corus Quay has achieved LEED Gold Certification with sustainable features including a four-storey biofilter, green roofs and rainwater recycling.


The building’s scheme is a series of geometries with upper floors set back and a large glazed atrium that drives daylight deep inside. Large doors open onto the lake, furthering the connection with the public space.


The living wall biofilter – an installation of tropical plants adorning office, academic, commercial and civic buildings – is a sustainable design response to create a healthy indoor environment and lower the carbon footprint.


Developed by Dr. Alan Darlington and introduced commercially by Diamond Schmitt Architects at the University of Guelph Humber campus in Toronto, the success of the prototype launched NEDLAW Living Walls with its patented green technology and has generated dozens of collaborations between the two firms in North America.


“We were looking for a way to feature biofiltration research undertaken by the University of Guelph for their Humber academic building a decade ago,” said Donald Schmitt, Principal, Diamond Schmitt Architects.


The research showed indoor air can be cleansed of pollutants such as carbon monoxide, moulds and bacteria and Volatile Organ Compounds (VOCs) through exposure to the beneficial microorganisms on plant roots. Suspended in woven, porous material, the roots of these hydroponically grown plants breakdown these compounds and produce no toxic waste by-product. By connecting a living wall to a building’s HVAC system, the treated air is humidified and over 80 percent of indoor air contaminants are removed.


Darlington’s early research funded by Canadian and European Space agencies to purify the air on proposed extraterrestrial bases led him to Earth-bound applications. “When we installed Guelph Humber, we were confident that the system should work, that ‘in principle’ it would clean the air,” he said. “Ten years on, we now we have a very good library of data demonstrating how well the technology works. If anything, the system has exceeded our initial ideas about its impact on the indoor space.”


The living walls designed by Diamond Schmitt Architects are typically between two to four stories high and integrated into a building plan at the schematic design stage. Their presence informs atrium orientation and skylight design to maximize the amount of natural daylight that reaches the plants. This attractive green feature becomes a focal point for gathering and is testament to the positive impact of plants on human health. Anecdotal evidence of living walls indicates improved productivity, reduced sick days and creating a better sense of wellbeing. “Bringing significant plant life indoors has universal appeal and appears to resonate with people on a primal level, hence the psychological benefit,” said Birgit Siber, Principal at Diamond Schmitt Architects. “But the real beauty is that it works on so many different levels, reducing the energy needed to treat outdoor air, providing fresh oxygen, creating acoustic absorption and white noise from the gravity water flow, and a compelling visual aesthetic not to mention a powerful symbol of green design.”


Since the first living wall, Diamond Schmitt and NEDLAW have explored additional synergies with clients on the use of biofilters. “It’s particularly gratifying to see living walls become part of the curriculum in academic buildings where they are featured,” said Schmitt. Drexel University’s Papadakis Integrated Sciences building in Philadelphia has a new field of research in microbial root communities. The LEED Platinum Algonquin Centre for Construction Excellence at Ottawa’s Algonquin College uses its five-storey living wall to enrich the study and practice of green building design.


The first living wall at U. of Guelph Humber is growing strong today. Others are featured at Diamond Schmitt’s Cambridge, Ontario City Hall, Corus Quay office building and Centennial College Library in Toronto, at the Royal Botanical Gardens in Burlington, Ontario, and at Thompson Rivers University in Kamloops, B.C. The largest to date is a six-storey biofilter at University of Ottawa’s Vanier Hall. An office building and hotel under construction in Buffalo, New York will also include a four-storey living wall.

Built to LEED® Gold certification standards, the building incorporates such sustainable initiatives as a green roof, low-emitting materials and rainwater reuse. A major feature of the structure is the multistorey, glazed atrium which bisects the building and faces the waterfront. It features an impressive living biofilter wall designed to improve the standard of indoor air quality and act as a large-scale focal point.
