The Co-operators’ Headquarters in Guelph, Ontario has been certified a 'Zero Carbon Building' by the Canada Green Building Council. The project is also targeting LEED Gold and WELL Platinum.
The renovation project covers three floors totalling 226,000 ft2, and includes a data centre, cafeteria, fitness centre, conference rooms, and three-storey open atrium. HH Angus provided mechanical and electrical consulting engineering, as well as IMIT and lighting design.
The building features an all-electric design to eliminate direct carbon emissions from any on-site source. This means that the company did not need to undertake any retrofits or decarbonization plans to achieve net zero targets. The building has been designed to be highly energy-efficient and to minimize indirect annual carbon emissions from electricity.
Any remaining emissions will be offset through high-quality carbon offsets or carbon-free renewable energy sources. The construction process was also meaningfully reduced, offsetting “embodied carbon” emissions resulting from the manufacture, transportation, and disposal of all building materials.
The Canada Green Building Council has identified the building sector as Canada’s third-largest emitter of greenhouse gases (GHG). Presently, residential, commercial, and institutional buildings are responsible for 17% of Canada’s GHG emissions, and this figure approaches 30% when building materials and construction processes are taken into account.
Despite an aggressive construction schedule, the project overcame the challenges of integrating an all-electric design and achieving Zero Carbon Building certification. It also intended to surpass goals for energy and GHG savings beyond the Ontario Building Code’s all-electric baseline and heating load reduction minimum for new builds. The building features a rooftop solar array and a high-efficiency water source, showcasing innovative approaches to sustainable design.
The building’s low-impact features include:
- Energy and GHG savings 40% greater than the Ontario Building Code’s all-electric baseline
- 60% reduced heating load, surpassing the minimum code requirement for new office builds requirement for new office builds
- A 282 kW rooftop solar array that is expected to produce ~9% of the building’s annual total energy
- Automatic window tinting to reduce glare and save energy
- A highly-insulated and airtight envelope to conserve energy
- High-efficiency water source technology to recover and redistribute heat throughout the building
- LED lighting equipped with occupancy and daylight harvesting sensors that turn on only when needed

Royal Inland Hospital
New Patient Care Tower
Royal Inland Hospital is a tertiary level acute care hospital serving a catchment area of approximately 220,000 residents in the city of Kamloops and throughout the Thompson, Cariboo and Shuswap regions of British Columbia.
The 290,625 ft2 new Phil & Jennie Gaglardi Patient Care Tower (PCT) is a nine-storey building that includes a surgical floor, 13 operating suites, patient floors for mental health and medical/surgical beds, a neurosciences and trauma unit, perinatal centre, labour and delivery rooms, and neonatal intensive care unit. There are also two underground parking levels, administrative and clinical spaces on three lower floors, an intermediate mechanical floor, and 3 inpatient levels topped by a penthouse containing the heating, cooling, and emergency power plant.
Phase 2, currently underway, consists of a number of renovations within the existing facility, including a completely renovated Emergency Department. Phase 1, which opened in July 2022, targeted LEED Gold certification. HH Angus provided mechanical and electrical design services for the PCT, which was constructed adjacent to the existing hospital under a P3 contract.
Designed with direct input from local healthcare workers, the PCT streamlines access to hospital services through a single main entrance. A new post-anaesthetic recovery room in the adjacent existing facility’s renovated space will be constructed in Phase 2. Other clinical spaces include a substance use inpatient unit, a child and adolescent mental health crisis intervention program, maternal and child services, and respiratory therapy services. Non-clinical spaces include reception, patient registration, a rooftop helipad, underground parkade, retail space and a new home for the Royal Inland Hospital Foundation.
Mechanical design includes energy-efficient heating and cooling systems with a variety of heat recovery features. The project has an ambitious energy use target and HVAC systems were designed with this benchmark in mind. HH Angus was able to solve a problem the Hospital was having with the existing distributed hot water boilers by upsizing the new plant to serve the majority of the hospital campus. The ventilation design includes redundant capability and outbreak control, and exhaust air heat recovery, as well as providing for future flexibility.
The Health Authority expressed an interest in the ability to conduct smudging ceremonies in any patient room without having to make significant modifications to the current ventilation design and infrastructure included in the project. HH Angus found a means for using the ventilation system as originally designed and applying a unique operational sequence to minimize capital cost changes while providing the ability to undertake smudging activities in any of the patient rooms on the Medical/Surgical and Mental Health Adaptive inpatient units.
A central focus of the design team was to work with the commissioning team to ensure proper operation of the new facility. The design team is now helping monitor ongoing operations to recover and reuse as much waste heat as possible. This effort concentrates on the heat recovery chiller plant operation to meet as much of the building’s heating load as possible using waste heat. This contributes to minimizing the production of GHGs from heating energy sources and, in turn, improves decarbonization for the new facility. New electrical services include a 25 KV service from BC Hydro serving a new outdoor substation powering the existing campus and PCT. New redundant 25kV to 600V FR3 transformers feeding the new tower were provided in the new main electrical room. Three new 2MVA diesel generators provide emergency power backup to the new patient care tower and the rest of the existing campus if utility power is lost. 600V distribution on both utility and generator power are provided with high resistance grounding to increase resiliency and reliability in the event of a single ground fault. Numerous low voltage systems were provided including fire alarm, lighting control system complete with daylight harvesting, circadian rhythm tunable lighting in the Neo-natal ICU, and electrical metering.

The rooftop helipad is served by a number of mechanical and electrical systems to help keep the pad surface clear of snow and ice and to provide appropriate safety lighting to meet all requirements. Fire protection and life safety systems, such as foam suppression, were carefully coordinated and designed to ensure full coverage and containment in the event of a discharge.
Integration with the existing hospital systems was a significant challenge and required numerous connections to the adjacent facility. Requiring multiple site visits, it was determined the two facilities could be successfully integrated by enclosing an outdoor courtyard between them, transforming it into a four-season space that will benefit patients, staff and visitors. On the electrical side, backfeeding the existing facility with new 600V HRG generator backup required careful analysis of existing distribution to ensure compatibility for all existing equipment to the new 3 wire distribution on emergency power. A detailed sequence of operations for black start sequence and retransfer of automatic transfer switches to normal was developed and commissioned to ensure proper operation for different failure scenarios.
The McEwan Group
Fabbrica's second location was designed as a take-out venue. The 4200 ft2 retail space is accessed via Toronto's underground PATH system, in the heart of the city's financial district. Fabbrica on the PATH joins its sister outlet across the hall, the McEwan grocery store.
HH Angus was engaged to provide mechanical, electrical and lighting design services for the tenant fitout of the new Fabbrica on the concourse level of the TD Centre. Fabbrica took over an existing space which required ceiling demolition in order to install new lighting and electrical systems.
Custom interior lighting was designed to attract the attention of commuters and shoppers in the PATH system. To achieve this, 3500K 12W high-colour-rendering LEDs were incorporated into the lighting design to showcase the vibrant colours of the meal offerings prepared for hungry consumers.
The project's location in the concourse level posed a design challenge to the team, due to the modest amount of ceiling and underfloor clearance. To accommodate these restrictions, HH Angus designed solutions to manage the routing of piping, conduits and drainage within the limited space.

Toronto Transit Commission
Waterfront East LRT - Union Station and Queens Quay Link
The existing streetcar service begins underground at Union Station, extends south under Bay Street towards Queens Quay Station, and continues west under Queens Quay before surfacing at the portal just west of Harbour Square. The expansion will include for a new portal on Queens Quay West, between Bay and Yonge Streets, to allow for service expansion eastward along the surface of Queens Quay West.
HH Angus was engaged to provide mechanical and electrical consulting services for Preliminary Design Engineering for the Waterfront East LRT project. The work includes a Baseline Design (~ 30% design completion), a Class 3 AACE Construction Cost Estimate, and Level 3 project delivery schedule. This is to accommodate the growth and future passenger volume as part of Toronto’s waterfront revitalization project for the expansion of the existing Union and Queens Quay LRT Stations, and a new running tunnel and portal.
The upgrade will expand on the single track Union Streetcar Loop with a split unloading and boarding platform to become a side-platform station, with each platform capable of accommodating two vehicles simultaneously. An additional by-pass track with special trackwork on the outside of the passenger boarding/unloading track will also be accommodated within the station.
The existing side platform at the Queens Quay station will also be upgraded to accommodate two vehicles simultaneously boarding/unloading at each platform. In addition, the station will provide access to the Jack Layton Ferry Terminal and Toronto’s downtown underground PATH network.
The tunnel ventilation solution—providing at-grade ventilation shafts within a land-locked congested downtown area—required a thorough understanding of various design criteria, as well as meticulous coordination with Architectural, Structural and Civil Utilities disciplines. The final design would entail further computational design analysis beyond the scope of this project in order to address a design variance.
For the overhead catenary system, the team drew on involvement with previous projects (where we were not the designer of said system) to adapt and provide a tailored solution for the unique project requirement of traction power delivery within stations, tunnels, portals, above-grade and transitions in between, working closely with Civil Trackway and Structural disciplines.
