The University of Toronto at Mississauga (UTM) has developed a number of unique buildings to serve the students on its campus. The Instructional Centre at UTM is no different. Clad in a Zahner pre-patinated copper surface, this custom blue patina on copper was developed specifically for the project.
The patina was an inspired decision by the architects at Perkins + Will whose design required a number of unique aspects for both the interior and exterior of the building.
The architects wanted a facade with an artistic patina, revealing the bare copper in some areas, and hitting dark points in others. This mottled appearance appears natural, but it is manufactured by Zahner.
The award-winning University of Toronto Instruction Centre's new building is certified LEED Silver, and was completed in 2011.
Under normal circumstances, raw copper sheet will develop a copper patina after ten to twenty years. In the case of the UTM Instructional Centre, this patina was developed in a matter of weeks by chemically oxidizing the metal in a controlled environment.
Zahner patina technicians developed a custom Star Blue patina on the copper, modifying its application technique for artistic effect. Zahner cultivates and trains patination experts for both their scientific prowess as well as their artistic vision, because many clients require a high-performance artistic patinated panel rather than a uniform machine-produced surface.
These copper sheets were then formed by Zahner into a panels. The prefabricated panels were crated and shipped to the job site in Toronto, where the pre-patinated panels were installed.
