20-storey building (300 units)
255 Riverside Drive East is a 20-story, 300-unit non-profit housing building originally constructed circa 1975.
As one of the largest social housing providers in Ontario, Windsor Essex Community Housing Corporation (CHC) has a deep commitment to sustainability, implementing projects at their existing buildings that are targeting the highest performance levels and creating new high performing buildings. With that in mind, Pretium was selected to be the Prime Consultant to complete CHC’s first Step-Wise EnerPHit project at Riverside Drive.
The project team conducted a feasibility study to determine options for each of the systems requiring renovation. Eighteen scenarios were modeled in PHPP with changes to the:
- Exterior cladding
- Balconies
- Roof assembly
- Floor slab and foundation walls
- Ventilation design
- Domestic hot water system
- Vent stacks
- Penthouse
- Lighting
The design options were narrowed down based on the EnerPHit requirements, impact on residents, and price until an optimal recommendation was achieved. Energy modeling and reporting for the National Housing
Co-Investment Fund was also completed.
Specifications for the renovation were prepared including the preparation of detailed drawings, permit application, and architectural renderings for the new exterior cladding. Construction review and contract administration services
are ongoing with mechanical system installation complete and building envelope upgrades scheduled to be complete in July 2024.
To deliver this project, Pretium completed the following measures:
Condition Assessment and/or Feasibility Study
A detailed assessment of existing conditions, including drawings, permitted use, failure mechanisms, and remedial options, allows for clients to choose the building restoration and renewal program that best suits their objectives.
Energy Modelling
A quantitative tool that assists designers in evaluating the environmental, technical, and financial viability of a proposed building retrofit or design for a new building. The data obtained from the analysis allows designers to communicate recommendations to building owners and managers more effectively. The information is used to identify optimal solutions.
Design and Specification
Design documents describe the project scope, materials, and procedures based on information collected during the assessment/feasibility phase with the Owner’s agreement on approach and budget. They communicate to the contractor in a way that promotes refined pricing and increases the potential for success through improved workmanship, fewer changes and disruptions to occupants, a shorter schedule, and cost within budget.
Tendering
A fair and competitive tender process is followed for both public and private projects. During the tender process, we respond to queries, prepare addenda, and walk the work area with the bidders. On closing of tenders, we prepare a written summary and analysis of the bids received.
Contract Administration and Construction Review
Once a contractor is selected, our team periodically visits the site to confirm that the work is being completed in accordance with the project specifications and provides contract administration from start to completion.
The building has been given new life, with all upgraded systems and an eye-catching black, white, and blue exterior. The benefits of this project do not stop at the extended life and curb appeal:

8 story building (60 units)
Hamilton East Kiwanis Non-Profit Homes decided to build a new mid-rise building at 6 Acorn Street in Hamilton.
While the project did not specifically target Passive House Certification, the Owners tasked the design team with delivering a building that could achieve Passive House performance levels.
Pretium was engaged to create an energy modeling of the proposed design using designPH and PHPP software to confirm the performance was meeting the stringent targets. During both the design and construction phases, Pretium provided third-party Building Enclosure Commissioning services.
Our role involved reviewing documentation and construction to ensure alignment with the Owner’s Project Requirements.
Pretium also completed air tightness testing on a mock-up unit to confirm that the target of 0.6 ACH @ 50Pa had been achieved. As part of the testing, tracer gas was used to identify deficiencies in the building enclosure. These were then addressed by the Contractor prior to re-testing.
To deliver this project, Pretium completed the following measures:
Energy Modeling
A quantitative tool that assists designers in evaluating the environmental, technical, and financial viability of a proposed building retrofit or design for a new building. The data obtained from the analysis allows designers to communicate recommendations to building owners and managers more effectively. The information is used to identify optimal solutions.
Building Enclosure Commissioning
An ideal BECx project engages a third-party Building Enclosure Commissioning Agent (BECxA) from Pre-Design through Occupancy and Operations. Through the commissioning process, we work with both the design team and contractor on the project to deliver an exterior enclosure that meets or exceeds the client’s performance targets.
Air Tightness Testing
Both qualitative and quantitative air leakage testing of building envelope components, compartments, or whole buildings is provided including, but not limited to, in-situ performance testing of windows and doors, and the use of a smoke-generating device in conjunction with blower doors to identify and resolve air infiltration issues.
