Michael Garron Hospital
Ken and Marilyn Thomson Patient Care Centre
Michael Garron Hospital’s new 8-storey Patient Care Centre includes inpatient and mental health beds, ambulatory clinics and an underground parkade. The project also encompasses ~100,000 ft2 of renovations within the existing hospital.
Much of the existing infrastructure at Michael Garron Hospital (MGH) reached the end of its lifecycle, with some buildings dating to the 1920s. HH Angus was engaged as part of the Planning Design and Compliance Team (PDC) for the new Patient Care Centre, responsible for generating performance-based documents to facilitate design of the new facility.
The project specific output specifications development process included options for expanding central plant systems (heating and cooling), augmenting and unifying the campus emergency power system, replacing aged electrical substations, phasing, design standards, and technical guidelines. Incorporating operations, life cycle and maintainability requirements were of the utmost importance for this project, as responsibility for the ongoing facilities operation and maintenance rests with MGH.
Enabling projects
To prepare the site for construction, several physical elements were relocated and/or demolished. HH Angus worked with MGH to provide mechanical and electrical engineering for the “Enabling Projects”.
These included relocation of bulk oxygen and bulk nitrous oxide, relocation of bulk chemical storage, demolition of E-Wing and F-podium, and decommissioning a major service tunnel. This work involved complex sequential construction phasing and shutdowns to maintain operation of the Hospital.
HH Angus’ ICAT group, Angus Connect, assisted MGH with development of a long-term strategic vision, directions, gap analysis, strategic recommendations and IT solution options for information technology (IT) to support the hospital moving forward. The team built on this strategy document to develop the design specifications as part of the compliance role.
The new Patient Care Centre is Phase 1 of an ongoing redevelopment, and is targeting LEED Silver.

District Energy System Cogeneration Plant
District energy is a key component of Toronto’s climate action plan, to reduce emissions from buildings and help the City reach its greenhouse gas (GHG) reduction target of 80% by 2050. Buildings currently generate about half of the GHG emissions in Toronto.
Enwave is the largest District Energy Systems in North America. The system has enough power to supply over 180 office buildings.
This project started in 1962 with an original feasibility study and culminated in the design and construction of a central plant and distribution system with an installed capacity of 800,000 lbs. of steam per hour.
The deep lake cooling system was added later, and makes use of the 40°F/4°C water in Lake Ontario. It has a total capacity of 75,000 tons of refrigeration, which is sufficient to air condition 3.2 million m2 / ~34 million ft2 offices.
Clients with whom we have worked on the Enwave District Energy System include:
- Hudson Bay Company
- Bank of Nova Scotia
- Cadillac Fairview Toronto Dominion Tower Plaza
- Royal Bank Plaza
- Mt. Sinai Hospital
- Toronto General Hospital
- Women’s College Hospital
- The Hospital for Sick Children

BESS & Microgrid System
The battery energy storage system facility reduces electrical demand for a Class A electricity facility operating during anticipated Global Adjustment hours.
Johnson Controls, the turnkey EPC and facility energy service company, engaged HH Angus to engineer a 2 MWe (4 MWh) behind-the-meter battery energy storage system (BESS).
The installation is part of a microgrid design that incorporates rooftop solar panels for six buildings (~500kWe), a 2 MWe (4 MWh) BESS, and a 2 MWe natural gas engine-generator peaker. The goal of the installation is to reduce Global Adjustment charges. It also supports much of the facility in the event of a power failure on the grid.
The solar panels and BESS were installed during spring and summer of 2018, and the engine-generator peaker plant has been submitted for a building permit.

Professional Gallery
The OCAD Gallery is the flagship professional gallery for the Ontario College of Art and Design, Canada’s largest and oldest educational institution for art and design. It serves as an experimental curatorial platform for art, design and new media.
HH Angus was tasked with the mechanical, electrical and lighting design for this 755 m2/8,200 ft2 facility. It includes gallery space, a media lounge, permanent art collection and storage, administration support services and shipping and receiving areas.
This project provided interesting design challenges to protect the art from potential water leakage from the tenants on the floor above. The ceiling is covered in a white waterproof membrane, which made recessed luminaires impractical.
The ceiling beams have a dual purpose – to support the track luminaires and to create an artistic industrial feel for the space. The track is two circuit to allow for maximum flexibility. LED track heads are 3500K with a CRI above 93 to enhance the colour of artwork in the exhibits. The track heads were chosen to allow for multiple and varied beams spreads, to enhance each exhibit and to provide flexibility by accommodating different lensing and media. Suspended linear LED luminaires were used in non-gallery spaces. Various power and data systems were used throughout the premises.
The heating and ventilation systems were designed to meet the mechanical requirements for a Class ‘A’ Art Gallery. The mechanical requirements for the Gallery consist of controlled humidification levels and temperature range. To achieve the requirements, a separate dedicated standalone mechanical air conditioning/humidification system was designed for the space. An indoor dry cooler and a series of heat pumps are located throughout the facility. Each heat pump has an associated electric humidifier and associated condensate pumps.

Tunney’s Pasture
HH Angus was engaged as Prime Consultant on a chiller plant installation for this public building in Ottawa. The project installation serviced nineteen buildings with a total floor space of ~3,170,000 ft2 and was comprised of two chillers @3500 tons.
Tunney’s Pasture is a 49-hectare (121 acre) mixed-use campus in Ottawa, including government services, commercial offices and residential buildings. Its existing steam-driven chillers were at end of life and operating with R22 refrigerant, the import and production of which is banned as of January 2020. Also, the use of river water for free cooling needed improvement and the river water pumping system was not operating efficiently.
HH Angus, in joint venture with Goodkey Weedmark, was retained to undertake conceptual studies to evaluate changing the chillers from steam power to electrical power. We also made recommendations for improving the free cooling aspects of river water and making more effective use of the river water pumping system.
HH Angus provided conceptual evaluation of replacing the chillers, in terms of efficiency, physical location and necessary steps required to change from steam to electrical power. Once the chiller concept was resolved, we evaluated optimization of the river water pumps to undertake the condenser water cooling and considered how to efficiently use the free cooling available from the river in low load conditions.
Optimizing free cooling and condenser water, using river water instead of cooling towers, resulted in energy efficiency and reduced carbon footprint for this installation. We also identified benefits to the client through improvement in chiller efficiency using the latest technology, and the elimination of boiler operation during the summer months.
