Canadian Centre for Inland Waterways Lab
The PSPC Canadian Centre for Inland Waterways Lab was originally constructed in 1967 and had not undergone significant modernization.
The lab’s research involves aquatic ecology hydrology, toxicology, physical geography, limnology, and environmental chemistry. The lab is home to the world’s largest circulated flume, distinguished ecotoxicological wet lab, calibration facilities, specialized water quality analysis and aquatic ecosystems laboratories.
The goal of the renovation was to focus on energy efficiency and climate change improvements for the building. The lab modernization project comprised the redevelopment of the Administrative and Laboratory building floors 4 through 7 which remained operational during the construction.
With a phased installation, the project required temporary services to be maintained to allow for the transition of work spaces during the renovation between Levels 4-7 of the building. This was an infrastructure dense lab with a floor fixed to an underside of slab and main service corridors and shafts.
Energy efficiency improvements included daylight harvesting, heat recovery, fume exhaust system consolidation and low flow variable fume hoods with room control ventilation rates.
To bring the building up to modern fire protection standards, a new sprinkler system was designed and installed as sprinklers were not required under the original 1967 codes.

Toronto Western Hospital
New Patient and Surgical Tower
University Health Network’s (UHN) new $1 billion, 15-storey patient care and surgical tower will be built on Toronto Western Hospital’s (TWH) campus in downtown Toronto and enhance UHN’s capabilities caring for complex neurological and orthopedic cases.
We’re excited to be part of this important and transformative healthcare project for UHN. HH Angus, in partnership with DIALOG, is providing mechanical and electrical engineering and ICAT/IMIT design services for the new tower.
The new facility will be over 380,000 ft2 in size over 15-storeys and include 11 clinical program floors, 82 beds, and 20 operating rooms of which three will be hybrid ORs with cutting-edge imaging capabilities.
The new tower will feature many of the latest healthcare technological advancements. We have supported UHN in developing a Digital Strategy for this facility and have incorporated technologies such as real-time locating systems for patient journey tracking, advanced audio-visual systems for information sharing, and surgical suite technologies to improve flow, communication and educational opportunities.
Among the electrical systems features, emergency generators sized for full backup and a central UPS will improve the resilience of this critical facility.

KEY SCOPE ELEMENTS
Targeting 32% energy reduction | Wastewater energy transfer (WET) system for heating, cooling, steam and domestic hot water

Sustainable Engineering
Building on our decarbonization and sustainability experience for healthcare clients across the country, TWH’s new tower strives to be Net Zero, targeting an overall 32% reduction in energy consumption from the OBC SB-10 (2017) reference model through a variety of initiatives, including integrating with UHN’s wastewater energy transfer system for heating, cooling, steam and domestic hot water. The mechanical design also includes energy recovery wheels on the ventilation system and considerations for predicted future climate conditions.
Proud Partnership
HH Angus is proud to continue collaborating with UHN – ranked number one on the 2023 list of Canada’s Top 40 Research Hospitals – a relationship that spans several decades working on many of their key facilities. Recent collaborations include a major upgrade at TWH’s Power House, which significantly improved the reliability of critical mechanical and electrical infrastructure in order to maintain the integrity of OR services, and the Rapid Assessment Centre Expansion at the Toronto General Hospital.
