Waypoint Centre for Mental Health Care 

Chigamik Community Health Hub

Waypoint Chigamik Mental Health Centre is part of a redevelopment project and replaces two older facilities in use since the 1800s. 

The challenges of this project included the requirement that the entire building be completely designed in one stage, rather than proceeding with design packages, plus delays in funding during the design process which resulted in a requirement for both a base building package and a fitout package.

To accomplish this, HH Angus coordinated two tender packages and two building permit submissions. Some detailed specifications in each package were interchangeable for the mechanical and electrical tender process. Working with phased schedules ensured that equipment start-up was fully coordinated between the tender packages.

The project faced additional challenges to provide an energy-efficient HVAC system, due to compliance with CSA Z317.2 and budget restrictions, as well as a small mechanical service space. To overcome these challenges, extensive coordination was implemented throughout the project across all disciplines.

Enwave Energy Corporation

Pearl Street Energy Centre

The Pearl Street Energy Centre project has been honoured with an Award of Distinction at the Ontario Engineering Project Awards by the Association of Consulting Engineering Companies (ACEC).

Buildings in Toronto generate more than half of the city's greenhouse gas emissions. New technologies, like Enwave's expanded heat delivery system, will play a critical role in reducing our cumulative carbon footprint.

This project exemplifies cutting-edge engineering and design, integrating robust energy solutions that challenge traditional methods.  Our focus on sustainable and efficient energy use through advanced engineering practices not only supports but advances the environmental goals of urban energy systems. HH Angus is the Prime Consultant and Mechanical and Electrical Design Engineers for the PSEC project. We are also acting as the design team project managers.

When fully utilized, Enwave's low carbon heating facility will provide enough low-carbon heating to reduce emissions in Toronto by approximately 11,600 tCO2e, the equivalent of converting over 10 million square feet of office space to net zero.

As part of the TransformTO Climate Action Plan, which outlines ways to improve the city’s health, grow the economy and improve social equity, district energy was identified as a key strategy. In 2017, Enwave was selected as a partner by Toronto’s City Council to help accelerate the implementation of the plan to reduce greenhouse gas emissions and make the city more resilient.

Enwave’s district energy system is the largest in North America. It serves 180 buildings comprising more than 40 million square feet through 4 interconnected downtown plants and 40 kilometres of underground pipes. The Pearl Street Energy Centre (PSEC) addition to the district energy system will expand Toronto’s district heating and cooling distribution and capacity using low carbon technologies, by installing 3600 tons of cooling and 62,000 Mbh (thousand BTU’s per hour) of heating using water source heat pumps (heat reclaim chillers). Enwave’s ‘Green Heat’ offering will be made possible by the installation of new assets that utilize waste heat while producing cooling and hot water.

The site offered some interesting complexities to be solved by the design team. The first was space constraints. As the existing Energy Centre did not have any space to house the new equipment, the only available space that could be used for the addition is a small corner on the lot where buried fuel oil tanks are present. A design was implemented to build over the tanks, one that would comply with the requirements of the Ontario Building Code and the Technical Standards and Safety Authority by leaving the ground level open for future removal of the tanks. All disciplines had to overcome many challenges due to space limitations, including structural, architectural, mechanical, and electrical.

A challenge for the mechanical design team centered on how to integrate the new heat pump system with the existing heating and cooling district system, as well as how to stage equipment without impacting Enwave’s existing customers and their stringent temperature requirements. Our solution was to design a false loading system to start and stage on additional heat pumps in order to avoid temperature spikes which would have negative impacts on customers’ critical data centre equipment.

According to the Canada Green Building Council, “it’s estimated that residential, commercial, and institutional buildings contribute 17% of Canada's greenhouse gas emissions today, and when building materials and construction are included, this level approaches 30%”. As the designers and engineers of these facilities, the AEC industry has an outsize role to play in ensuring the success of sustainable development.

HH Angus has a proven track record of promoting innovative and sustainable engineering solutions. We are committed to providing engineering solutions that reduce energy consumption and reduce or eliminate greenhouse gases.

Robarts Library, Reading Room Renovation

The Robarts Library, renowned as an example of the 'Brutalist' style of architecture, stands as one of Canada's largest academic library buildings, serving as a cornerstone of scholarly pursuit at the University of Toronto.

HH Angus provided mechanical and electrical engineering services, as well as design consulting for IMIT and lighting, for the renovation of the Library's fourth floor Reading Room.

The project, aimed at modernizing the library's facilities to accommodate contemporary learning paradigms, posed several intricate challenges. One notable challenge involved the intricate design of cabling for security and telecoms within the limited capacity channels of the floor slab, while ensuring the preservation of the library's architectural integrity. Moreover, the integration of wireless thermostats for HVAC control demanded meticulous planning to guarantee effective functionality while maintaining the library's iconic aesthetic.

In response to the evolving needs of the campus community, the renovated space has been thoughtfully curated to foster a conducive environment for study, collaboration, and digital scholarship. Individual study areas, equipped with state-of-the-art digital stations and consultation rooms, offer students and faculty alike the resources they need to thrive academically. Additionally, the incorporation of light therapy zones underscores a commitment to promoting wellness and inclusivity within the Library's patrons.

Improved accessibility was a key aspect of this renovation, featuring new study spots with adjustable desk heights, versatile seating configurations, and customizable lighting options, ensuring that all user's needs are considered. As well, strategic wayfinding elements and clear sightlines have been implemented to facilitate seamless navigation throughout the revitalized space.

Burnhamthorpe Community Centre Renovation and Expansion

The Community Centre features a state-of-the-art aquatic centre as well as an equipment-based fitness centre. The new 31,990 ft2 wing is the first project designed and built to the City’s corporate Green Building standard. This standard requires that all major renovation projects for city buildings meet LEED Silver requirements.

HH Angus played a key role in this project, providing mechanical and electrical engineering services, as well as security, IMIT, lighting, AV, and plumbing design. The addition includes a new 25-metre, 6-lane pool, therapeutic pool, fitness centre, and common areas, for a total of 43,000 ft2 of added amenities.

Renovations to the existing community centre encompass improvements across 65,000 ft2, repurposing and relocating multi-purpose program spaces, gymnasium, indoor arena, and upgrading facilities to meet accessibility and green development standards. Despite challenges posed in connecting to the existing building, the addition was situated on the northeast corner, utilizing space from the adjacent park.
