OAA Webinar | Reimagination of 60 Bloor Street: A Deep Retrofit Case Study

11:00 AM - 12:30 PM

Webinar Description

The deep building retrofit at 60 Bloor Street West, a 1970s-vintage, 300,000-sf office building at the landmark intersection of Bay and Bloor streets in Toronto, is at the leading edge of a trend toward large-scale existing building retrofits in Canada. Morguard, in partnership with Ledcor Renew and C3 SGS, identified the potential for real value growth through a retrofit that includes significant mechanical and electrical upgrades, installation of a modern building envelope with over 35 per cent greater daylight openings, and major upgrades to the building’s retail podium—all while the building is fully occupied. The project is targeting an energy use reduction of more than 25 per cent and pursuing LEED EB: O&M Gold certification.

This presentation focuses primarily on the building envelope considerations, including the design and installation of a bespoke curtain wall system. The upper portion of the existing metal spandrel panels and the structural aluminum fins are removed from the exterior prior to installation of the new unitized curtain wall. The new curtain wall is mechanically fastened to the existing glaze spline. Finally, the original vision glass is removed to the interior. The interior works also include a significant HVAC retrofit.

Learning Objectives

  1. Learn about the different methods of retrofit, and their relative advantages and disadvantages.
  2. Understand the challenges of preparing for and implementing a retrofit on an occupied building.
  3. Understand the options for obtaining LEED certification on an existing building retrofit.
  4. Learn about new, innovative approaches that should be considered.
