Schroeder Ambulatory Centre

Healthcare Facility

The Schroeder Ambulatory Centre is a transformative healthcare facility in Richmond Hill that has been developed to help address growing demand for outpatient surgeries, diagnostic imaging, and other ambulatory care services across Ontario.

As one of the largest non-profit multidisciplinary ambulatory care centres in Canada, the facility was created to improve access to publicly funded healthcare, reduce wait times, and relieve pressure on hospitals by shifting high-volume, lower-complexity procedures into a purpose-designed community setting.

The project involved the adaptive reuse and redevelopment of an existing 200,000 ft2 medical office building into a modern healthcare environment focused on efficiency, patient experience, and clinical excellence, including base building upgrades to HVAC and power systems to meet CSA Standards and the fitout of 8 operating rooms, 5 procedure rooms, and associated support spaces. HH Angus provided comprehensive mechanical and electrical engineering, as well as communications and security consulting services, throughout the design and construction phases of the project.

Mechanical Scope
Our mechanical consulting services included a comprehensive review and coordination of all building systems. We assessed existing installations through 3D scanning, verified load calculations, equipment sizing, and code compliance. The scope included retrofitting existing systems and infrastructure to suit healthcare standards as well as adding new ventilation, steam and heating systems.

Electrical Scope
The electrical scope involved a thorough evaluation of existing electrical systems, ensuring compliance with design standards and regulatory codes. We prepared tender packages using existing documentation and Revit models. During construction, our team reviewed electrical submissions, attended site meetings, and interpreted contract documents as needed. We oversaw progress inspections, managed change notices, and supported commissioning coordination.

Award-winning* Lighting Design
The human-centric lighting design encompasses all types of spaces, including parking garage and site lighting, canopy illumination, transitional spaces, back-of-house support areas, and task-specific medical environments. The lighting strategy balances visual comfort with clinical performance, carefully calibrating luminaires to provide appropriate illuminance for procedures, circulation, and patient care.
*The project was honoured with a 2026 IES Toronto Section Award of Merit for excellence in lighting design.

By combining technical performance with thoughtful, patient-centered design, the Schroeder Ambulatory Centre establishes a benchmark for outpatient healthcare facilities, delivering an environment that is safe, accessible, and adaptable to the evolving needs of the community.

Quinte Health

Prince Edward County Memorial Hospital Redevelopment

The new Prince Edward County Memorial Hospital (PECMH) will be a leading-edge healthcare facility designed to met the current and future capacity needs of its local communities.

HH Angus was engaged by Quinte Health to provide the new hospital with mechanical and electrical engineering services, lighting, audio-visual, and security systems design, as well as energy modeling and ICAT digital strategy.

The project includes the construction of a new hospital with improved equipment and facilities, including a 24-hour emergency department, acute inpatient unit, helipad, surgical suite, diagnostic imaging, laboratory, dialysis unit, and other specializations.

Significantly, the PECMH will be the first acute care hospital in North America with an all-mass timber structure. Unencapsulated mass timber is faster and more accurate in construction compared to steel and concrete and sequesters carbon better than any other structural material. Use of mass timber is estimated to be saving the project over 9 million kilograms of embodied carbon dioxide compared to a conventional steel and concrete structure. Other sustainable aspects of the new building include energy-efficient windows, selection of sustainable materials and use of natural light in the building’s atrium.

Our systems design included a hybrid plant comprising a geo-exchange heat pump, gas-fired heating, domestic hot water generation and humidification elements. A six pipe, 200-ton geo-exchange heat pump has been designed to allow simultaneous heating and cooling to maximize efficiency performance. The geothermal system is expected to provide 50 percent of the hospital’s cooling and 90 percent of its heating. The new building will feature a solar panel installation on the roof, which will lower electricity operating costs and avoid the use of 2,000 tons of carbon during the panels’ lifespan.

Our ICAT team assisted in the development of a Digital Strategy to support the project. This included a current state assessment, visioning, implementation roadmap creation, and budget cost estimate. The ICAT scope of work also included systems integration design involving development of a comprehensive integration use case list through user engagement sessions, as well as developing the construction documents, consisting of an integration matrix, integration concept model / diagram, and integration specification.

The project was featured in Canadian Architect Magazine in April 2025, and in a 1-minute YouTube video.

Ontario Power Generation

Oshawa Headquarters

Ontario Power Generation set out to unite its various corporate offices into a single, modern facility that embodies collaboration, efficiency, and long-term sustainability. Repurposing the former GM headquarters brought new life to an iconic site. The project was recognized with a 2026 Award of Distinction from the Association of Consulting Engineering Companies - Ontario Chapter, and an IES Toronto Section Award of Merit for excellence in lighting design.

OPG selected Oshawa as its new corporate headquarters, purchasing and redeveloping a well-known building - the former General Motors (GM) administration building — a 285,000 ft2 facility with five levels (four storeys plus a lower concourse).

The project brought together OPG’s non-station staff from across the Greater Toronto area and Durham Region under one roof, transforming the existing structure through extensive interior and exterior renovations. Upgrades encompassed all major building systems, focusing on enhancing performance, comfort, and environmental responsibility.

HH Angus and Associates played a pivotal role as mechanical and electrical engineers, IMIT and lighting consultants, owner’s engineer, plumbing/fire protection/life safety designer, and commissioning authority.

The overarching goal was to create a future-ready workplace capable of supporting OPG’s operational and cultural needs for the next 40 years — targeting a net-zero carbon footprint and integrating leading sustainable design strategies throughout.

Meeting the objectives
HH Angus’ design solution had high sustainability and energy aspirations and involved the adaptive re-use and re-development of the GM administration building in Oshawa. HH Angus’ Commercial and Angus Connect teams came together for this project.

The project team successfully navigated a series of challenges that tested both creativity and collaboration, ultimately demonstrating their ability to deliver excellence under demanding conditions.

Materials and equipment
The unique use of materials was in fact the ‘re-use of materials’, significantly reducing deconstruction waste and embodied carbon. Much of the existing HVAC equipment was optimized (e.g., terminal heating and cooling devices) to enhance performance and capacity, rather than replacing the distribution network.

Internal resources, experience and expertise
To meet the demands of the accelerated schedule, the project team of mobilized a robust internal team, drawing on resources from across the firm. This collaborative effort, made possible by the firm’s size and depth of expertise, allowed us to maintain quality and precision while delivering on time.

Apart from strategic reuse of existing infrastructure, to accommodate increased occupancy, the design team included the use of energy recovery and thermal storage to allow system capacities to be sized below the peak demands to get the most out of the cost and embodied carbon of the equipment provided.

Outcome
Through ingenuity, collaboration, and technical excellence, the team successfully overcame these challenges—delivering a high-performance, cost-effective design that met the client’s objectives and ambitious goals, and reinforced their trust in the team’s ability to deliver innovative solutions under pressure.

Collaborative process

An interesting challenge was meeting the fixed project budget while delivering design integrity. To address this, the team dedicated many hours to an intensely collaborative process—partnering closely with manufacturers, vendors, and contractors to identify cost-effective solutions that preserved the client’s vision and design intent. Through innovative thinking, open communication, and strategic value engineering, the project was successfully delivered within budget while maintaining both functionality and aesthetic integrity.

Repurposing building systems

A further challenge emerged with the new interior layout, pushing existing building systems beyond their designed capacity. Rather than opting for a costly and disruptive full replacement of the distribution ductwork, the design team developed a strategic, resourceful solution. By introducing terminal heating and cooling devices to supplement the existing infrastructure, the required system performance was achieved efficiently and sustainably.

Balmoral Recreation Centre

Renovation and Expansion

The City of Brampton undertook an extensive revitalization of its existing 53-year old recreation centre.

The project involved a near-total demolition of the existing facility, with the exception of the steel structure of the pool and pool basin. The renovation and expansion have delivered an almost entirely new facility, nearly doubling the size of the former centre to 35,000 ft2. LEED Silver certification is in progress. HH Angus provided mechanical and electrical engineering, ICAT design, and lighting design services.

Key features include the rehabilitated pool, updated change rooms, a multi-sport gymnasium with an Olympic-sized FIBA court (smaller than an NBA court), a sauna, and two multi-purpose rooms that can open to create a more versatile space. The design also incorporates a large, interconnected lobby and administrative offices. Exterior improvements include additional onsite parking, as well as a new outdoor splash pad and playground.

The project replaces all air distribution systems serving the rehabilitated pool and introduces a new high-efficiency condensing boiler system to heat both the pool and the building perimeter. Heat recovery from discharged water is used to preheat incoming cold water for the pool, contributing to the achievement of multiple LEED credits. High-efficiency rooftop units equipped with heat pumps and heat recovery wheels significantly reduce overall energy consumption. Occupancy and CO₂ sensors further optimize performance by ramping mechanical systems up only when spaces are in use. Automatic curtains and daylighting strategies reduce energy demand for interior lighting, while low-flow plumbing fixtures throughout the facility help minimize water usage.
