Montréal Metropolitan Airport Terminal

Porter Aviation Holdings Inc., in partnership with Montréal Metropolitan Airport, has developed a new, fully electrified terminal to serve 4 million+ passengers annually.

Terminal construction began mid-2023, and opens to the public on June 15, 2026. The terminal was designed by Scott Associates Architects Inc., with HH Angus providing mechanical and electrical engineering services for the 20,000 m2 (225,000 ft2) terminal building (YHU). All systems have been designed to fully operate on electric power.

Features of the new facility include:

Modern design aesthetic, featuring natural light and high-quality materials
21,000 m2 (225,000 ft2)
9 bridged aircraft gates
Lounge-style seating for all passengers
Food and beverage concessions, and retail vendors
A fully-electrified facility with all building systems operating on electric power
State-of-the-art passenger and baggage processing, and security installations

Porter continues to expand its existing operations at the Trudeau Airport (YUL) in Montréal, while introducing a Canada-wide network at the YHU airport. YHU connects with both of Porter's Toronto hubs - Billy Bishop Toronto City Airport (YTZ) and Toronto Pearson International Airport (YYZ). The MET terminal will serve other airlines.

The YHU terminal development is modeled after the successful revitalization of the Billy Bishop Toronto City Airport that Porter has been a part of since 2006. After decades of declining passenger service at the island airport, Porter's commitment to YTZ was the catalyst for route developments and infrastructure investments that led to the airport serving nearly three million passengers annually, across more than 20 routes and producing $3 billion in annual economic impact. The YHU terminal will also provide faster passenger processing, resulting in travel time savings.

HH Angus is also working with Scott Associates Architects on Porter Aviation's two new massive aircraft hangars at the Ottawa Airport. Phase 1 was completed in late 2023 and Phase 2 in early 2024. They are part of a series of projects to revitalize the Ottawa Airport so that it can accommodate increased air travel demand in the National Capital Region. We were also involved with the original revitalization of the Billy Bishop Toronto City Airport, as well as its further expansion in 2014, and have been working with Porter Aviation since its inception.

Ottawa Airport Hangars

Porter Aviation Holdings Inc. has built two massive aircraft hangars at the Ottawa International Airport. At 150,000+ square feet and $65 million, the project was designed by Scott Associates Architects. PCL served as construction manager together with Span Construction & Engineering. HH Angus provided mechanical and electrical engineering to the project, as well as ICAT and security design.

The Porter hangars were constructed in two phases - the first was completed in late 2023, and the second in 2024 Q1. The complex is part of a series of projects to revitalize the Ottawa Airport to accommodate increased air travel demand in the National Capital Region, and will serve as a primary maintenance base, with 200 local hires, including 160 aircraft maintenance engineers, shop technicians and administrative support staff.

The hangars span approximately 86 metres, and house up to eight aircraft, along with various repair and parts modification shops.

One of the project’s key design criteria was to exceed current energy efficiency standards, in line with the airport’s commitment to net-zero operations by 2040 or sooner. The hangars were designed with sustainability in mind; for example, some of the important features include:

A predominantly electric fleet of vehicles for towing and servicing aircraft, as well as ground support
Design criteria exceeding current energy efficiency standards
Constructed with approximately 35% recycled steel that can be recycled at the facility’s end of life
Constructed from materials with 28% lower embodied carbon than conventional tilt-up assemblies
City fire hydrant system is fully supplemented by an onsite underground water storage tank capturing approximately 1.2 million litres of excess rain/stormwater to avoid overstressing existing city mains.

HH Angus is also working with Scott Associates Architects on Porter Aviation's Saint-Hubert Airport Terminal project, a new zero-carbon terminal that will serve an estimated four million passengers annually. We were also involved with the original revitalization of the Billy Bishop Toronto City Airport that was completed in 2011, as well as its further expansion in 2014, and have been working with Porter Aviation since its inception.

Mount Sinai Hospital

Phase 3A Redevelopment

Phase 3A represented the largest redevelopment in Mount Sinai's history. HH Angus was engaged to provide mechanical and electrical engineering for the Renew Sinai redevelopment.

HH Angus worked with the Hospital, Stantec Architecture and other consultants to develop the Functional Program and Blocks Schematics for Ministry of Health and Long-term Care [MOHLTC) stages 2 and 3.1 submissions.

As part of our scope, we were involved in the investigation of existing infrastructure and systems. The age of the existing facility, together with previous renovations and multiple facility architects and consultants provided a challenge in obtaining a complete set of existing design conditions. We were provided with drawings in various forms (eg: PDFs. scanned hand-drawn images, AutoCAD and part plans), ranging from the original build to the most current renovation projects. We translated the relevant information into AutoCAD and, in with numerous site investigations, assembled a comprehensive set of record drawings detailing the existing systems and functions.

The scope of the project included a new Surgery Department, renovated and expanded Emergency Department, Critical Care, Medical Device Reprocessing Department, Integrated Practice Unit, Ambulatory, and labs, as well as miscellaneous relocates and decants.

Some of the key challenges of this project included reworking the major mechanical and electrical infrastructure to upgrade systems to current standards, and the integration of disparate systems with existing facilities.

Extensive renovations were implemented. To address the challenges of implementing new infrastructure, HH Angus provided extensive background information and on-site investigation to mitigate risks to the Hospital.

Minimizing disruption to hospital services was of paramount concern in scheduling the renovations. To ensure continued hospital operations, our design solution included planned sequential shutdowns minimized inconvenience to staff, patients and visitors.

Under a standing offer with Mount Sinai, we served as Mechanical and Electrical Engineers of Record and were involved in a variety of projects for Phase 3, including: peer review, fluoroscopy unit. Maternity Clinic renovation, Mouse MRI Lab, Biorepository Lab, Roth Lab, Bremner Lab, Distributed Antenna Systems, lobby upgrade, art gallery/ security/office renovations, and IMIT Planning for Phase 3 Redevelopment and renovations to multiple departments.

The Co-operators

National Headquarters

The Co-operators’ Headquarters in Guelph, Ontario has been certified a 'Zero Carbon Building' by the Canada Green Building Council. The project has also achieved LEED® Gold and WELL Platinum certifications and is pursuing BOMA Best.

The project covers three floors totaling 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
Award-winning lighting design, including LED lighting equipped with occupancy and daylight harvesting sensors that turn on only when needed

Island Health | Infrastructure BC

Quw'utsun Valley Hospital/Quw'utsun Hulitun-ew't-hw (Cowichan)

Three times the size of the existing facility, the new Quw'utsun Valley Hospital (formerly Cowichan District Hospital Replacement Project) on Vancouver Island will reflect BC’s new model for integrated healthcare by placing patients, families and communities at the centre of care decisions throughout the continuum of care. The goal is to reduce wait times, improve care and outcomes, and provide better value for healthcare expenditures.

HH Angus is part of the design team under The EllisDon Healthcare Infrastructure Consortium, and is providing mechanical and electrical consulting engineering to the 607,000+ ft2 project. The new facility, with an estimated budget of $1.44 Billion, will have 204 private or semi-private beds to support best practices for infection prevention and control, with the capacity for increased beds as population growth warrants. The emergency department will be three times the size of the current ER and is expected to accommodate 42,000 visits by 2035. Additional services include mental health facilities featuring a 20-bed inpatient unit and dedicated ICU, culturally safe services and spaces, 7 operating rooms, increased CT scanning capacity, and built-in MRI facilities.

Island Health specified a low energy, low carbon design solution. HH Angus, working with the rest of the design team, devised a number of innovative solutions. The project is now Canada’s first CaGBC-certified 'Zero Carbon Building - Design Standard' hospital and is aiming to be the country's first fully electric hospital. As well, the project is targeting LEED Gold certification.

Sustainability has been at the core of the decision-making process for this project, with a focus on carbon reduction. Its ZCB – Design™ certification reflects achieving a 38% embodied carbon reduction from baseline and, as the first all-electric healthcare facility in British Columbia, the CDHRP’s design has an operational energy performance that significantly surpasses its target.

The design strategies focused on reducing the project's embodied carbon emissions, maximizing energy efficiency, electrifying the mechanical systems, using new-generation low GWP refrigerants, and designing an optimized PV array. The project also uses an air-source heat pump and electric hot water boilers.

This is the first Alliance Project Delivery for HH Angus, with many differences from a conventional project delivery model. It is a far more collaborative process, where the owner, contractor and design team act as one entity. Both the quality of the submitted design and the ability of the team to work together were key factors in the proponent evaluation.

The project is also the first hospital in BC to be certified 'Salmon Safe' for its watershed protection efforts, including reduced water use, on-site stormwater treatment, use of native and drought-tolerant trees, shrubs and plants, as well as enhancing and protecting important wetland ecosystems.
