A pair of design-built projects from PCL Constructors Canada received LEED certifications recently.
The Centre for Addiction and Mental Health’s (CAMH) McCain Complex Care and Recovery Centre and the Crisis and Critical Care Building and Mackenzie Health’s Cortellucci Vaughan Hospital were recognized for excellence in sustainability and green building leadership.
“Congratulations to all our clients, consultants and partners on this incredible achievement,” said Marc Pascoli, PCL Toronto’s senior vice-president and district manager. “Achieving LEED certification for these complex P3 projects demonstrate the strength in the collaborative relationships we have built with CAMH, Mackenzie Health and our partners and our commitment to a shared vision of a sustainable future.”
Completed on schedule and on budget despite a global pandemic, the McCain Complex Care and Recovery Centre and the Crisis and Critical Care Building, Phase 1C of the Centre for Addiction and Mental Health’s (CAMH) redevelopment project.
“Achieving LEED in healthcare adds to the complexity of both the design and construction. On the design side, we often wrestle with architecture and energy models to find the right advanced energy systems and varied materials to hit the LEED targets,” said Stephen Montgomery, sustainability advisor, mechanical and electrical pursuits manager. “The resulting design contains more, new, components, parts and building techniques that must have complete plans for procurement, quality, commissioning and turnover.
“Construction planning starts with design and does not end until the hospital is fully operational.”
Preserving green spaces and environmental stewardship were crucial to CAMH’s ‘Green on Queen’ vision for the new buildings. Highlights include:
- 17,000-square meter green roof and vegetated space accounts for 62 per cent of the site area, which is unique to projects of this size.
- Drought tolerant plants and high-efficiency irrigation system that reduce potable water consumption for irrigation by 100 per cent.
- Responsibly harvested wood throughout the building, with 98 per cent of all wood materials certified by the Forest Stewardship Council.
- Furniture meeting specified chemical content and environmental attributes; a feature that exceeded LEED Gold requirements and met LEED v4 requirement.
- Highly efficient building envelope focusing on minimizing thermal bridging and optimizing solar heat gains.
While facing unanticipated challenges during the peak of the COVID-19 global pandemic in August 2020, PCL reached substantial completion on Mackenzie Health’s Cortellucci Vaughan Hospital, the City of Vaughan’s first hospital and Ontario’s first net new hospital in the last 30 years.
Embracing energy efficiency and sustainability in the hospital’s planning, design and construction, Cortellucci Vaughan Hospital achieved LEED Silver certification earning 54 points.
- Extensive visible green roofs enhance views from inside and outside the building and contribute to the project’s sustainability goals.
- Larger patient room windows optimize energy performance and allow plenty of natural light.
- 39 per cent of total waste diverted on the site during construction.
- Low-emitting materials including adhesives, sealants, paints and flooring systems.
- Landscaping with planting and hardscape materials, including terraced gardens with stone retaining walls.
