ABSTRACT:
An investigation of the use of existing technologies to maximize the existing features and sustainability of a large abandoned downtown urban core building – 222 Jarvis Street in Toronto.

Cameron Hind, Executive Vice President, Hidi Rae Consulting Engineers
DESCRIPTION:
Toronto’s 222 Jarvis Street is a 535,000 sq. ft. existing commercial office building completed in 1971. The building was renovated to achieve LEED Gold certification by incorporating intelligent building design principles, reduced energy demand, resource conservation and the creation and support of an innovative and healthy workplace environment. The overall goal of the project was to achieve LEED Platinum for New Construction and Major Renovations and to fulfill the client’s social, economic and environmental objectives for excellence within a finite budget. The project achieved finalist status in the Zero Footprint Re-Skinning Award in the Large Commercial Category as presented in conjunction with The World Urban Forum.
The 222 Jarvis Sustainable Building Renewal project encapsulates a scope of work that was developed over a six-month period of detailed design. Exceptional synergy among a diverse team made this project unique; team members included: WZMH Architects, Enermodal Engineering Limited, Hidi Rae Consulting Engineers, Mulvey and Banani International Inc, A.W. Hooker Associates, Cost Consulting, Halcrow Yolles cladding consultants, and others. Integrated design principles led the team to reposition the building with cladding upgrades, add a new light well to illuminate the center of the building, completely upgrade the electrical systems and rebuild the mechanical systems to provide a combined 61% energy reduction. Enermodal created an energy model to ensure that each proposed sustainable measure was analyzed for value added benefit, systems integration and contribution to attain multiple LEED points.
This presentation will demonstrate the use of existing technologies systematically modeled and evaluated in combination in order to maximize existing features and for sustainability, culminating in new life for a large abandoned downtown urban core building. WZMH, Enermodal and Hidi Rae will describe the decision making process used to arrive at the final scope of work. Other current projects show the merits of alternate means and methods and why specific measures were selected in this case study.
