Heat Recovery Feasibility Study
HH Angus conducted a study to evaluate the feasibility of exhaust air heat recovery from the Global Relay (GR) data centre facility at 22 Gostick Place in North Vancouver, BC.
Some of the key aspects of the study included:
- The location and footprint of the heat recovery system components were studied within the context of considerable site constraints. The study evaluated the design, construction, and cost considerations for the implementation of the proposed heat recovery system.
- We investigated available heat pump technologies that would be appropriate for recovering waste heat and would satisfy the LEC DES requirements.
- The energy recovered would be used by a water source heat pump to provide hot water to the local LEC District Energy System (DES).
- A water source heat pump system was proposed as the best solution to provide the ability to recover heat from the building ventilation system. The new system would recover heat from the GR facility and would transfer this recovered heat via a hot water loop to the local LEC DES.
- Heat recovery is feasible for the facility and can provide up to 1,100 kW of heating capacity to the LEC DES.
- Constraints to the design of the heat recovery system were also identified, and included:
(i) the quantity of air exhausted from the facility is not fixed and ranges at each exhaust plenum on a seasonal basis and depending on outdoor air temperature – this impacts how much heat can be recovered at a given time;
(ii) the minimum and maximum exhaust air temperatures range from 30°C to 43°C (86°F to 110°F) - the temperature of the exhaust air will influence how much heat can be recovered from the exhaust air; and,
(iii) the cross-sectional area available for the heat recovery coil - the more cross-sectional area that is available for a given amount of heat transfer, the less deep the coil must be (and less airside pressure drop penalty is incurred).
The study concluded that a purpose-built containerized heat pump system would be the most suitable solution to meet the needs of the project. This new containerized structure would be conveniently located adjacent to the GR facility and would exhibit the same architectural character as the existing facility. The proposed heat pump system would include one heat pump unit (based on Emerson Heat Pumps) and four heat recovery water pumps. Control valves, piping accessories, ventilation, lighting, and system controls would all be included in the proposed pre-fabricated containerized enclosure.
Outdoor hydronic piping would connect the heat pump enclosure to the GR facility and the proposed hydronic heat recovery coil system. The heat recovery coil system would consist of four new heat recovery coils placed within the existing facility exhaust air plenums. The existing exhaust fan motors would have to be upgraded in order to address the additional pressure drop introduced by the new heat recovery coils. This fan motor upgrade would also trigger upgrades to the existing electrical infrastructure.

Thunder Bay Correctional Complex (TBCC)
The TBCC involves replacement of aging jail and correctional facilities with a new 345-bed, multipurpose complex. Both the existing Thunder Bay Jail and Thunder Bay Correctional Facility are among the oldest provincially-run adult correctional facilities, built in 1928 and 1965 respectively.
The new TBCC updates automation and technology to address issues of health, safety and security, and introduces efficiencies around design, technology, and the use of space. HH Angus is providing mechanical consulting engineering and vertical transportation consulting to the EllisDon Infrastructure Justice design team.
The TBCC is targeting LEED Silver certification and LEED Resilient Design pilot credits through the United States Green Building Council. The design focuses on energy efficiency, healthy indoor environments and reduced greenhouse gas emissions. The complex will also include views of nature, allow ample natural light and feature dedicated Indigenous cultural spaces, such as smudging space and sweat and teaching lodges.
The new facility is the first of its kind for an Ontario correctional facility, incorporating design features that promote rehabilitation of inmates. It will also improve access to programming, living conditions and education, while updating automation and technology.
The TBCC project has presented several challenges to our design team, including a compressed schedule and the involvement of numerous stakeholders. It has also been interesting on a technical level: mechanically, the various modes of operation and interconnection of systems are quite complex, necessitating a high degree of flexibility within the capacity of the mechanical equipment. The building construction featured a precast exterior with block walls, requiring very close coordination with trades to align openings and allow access for equipment.
Due to the secure nature of the facility, the mechanical system was integrated seamlessly into the architectural features, all accessible equipment is provided in a secure location, and all building systems interact
with the BAS.
The facility will include a connection to an existing 50-inmate facility — the Thunder Bay Modular Built Facility — located southeast of the TBCC and currently under construction. The project also involves the design and construction of a 4,000 ft2 wastewater treatment facility to allow for a fully self-sufficient and self-contained facility.

Collège Bois-de-Boulogne
Server Room Air Conditioning
Pavilion Saint-Paul
One of the challenges of this project was to replace the main and redundant cooling systems in the server room while maintaining operations and minimizing impact on the College.
HH Angus’ scope of work for this project included analyzing the mechanical and electrical infrastructure of the server room, and proposing permanent corrective solutions. It also included implementation of solutions to provide redundancy for the mechanical infrastructure to guarantee full operation of the servers in the event of a critical power emergency or failure of the server room's main cooling system.
In order to analyze the existing installations, we performed site visits and surveys, and interviewed technicians responsible for the server room to gather as much information as possible about the existing installation, including any ongoing issues. We also reviewed and analyzed plans for the existing installation and performed a condition assessment - chilled water and glycol piping, insulation, ventilation ducts, electrical systems serving the equipment, and control systems - and took measurements in the mechanical and server rooms to ensure the new equipment could be properly installed while still providing space for maintenance work.
Following our analysis, we produced a report outlining the scope of work to refurbish the server room's cooling systems (main and redundant systems), ensuring the installation complied with current codes and standards. We produced mechanical and electrical drawings and specifications, including proposed solutions and equipment selection, and consulted with vendors to identify optimal solutions to meet the client’s requirements. During the tender process, we reviewed bids submitted by the contractor and provided recommendations to the College.
The intention was to complete this work over the summer when classes were not in session. Due to COVID-related delays in production of the necessary equipment, the work could not be completed on the original schedule and had to be undertaken when students were back in class. We worked very closely with stakeholders to avoid disruption to the students, with some work being completed before and after class or on weekends.

WPP
Toronto Waterfront Campus
WPP Group's building is part of the largest urban revitalization project in North America, bringing together new businesses, restaurants, and transport connections.
Work Design Magazine March 28, 2023
This cutting-edge project on Toronto’s downtown waterfront represents an evolution in commercial office development and reinvents how employees work together in Toronto’s rapidly evolving creative and technology sectors. The new space merges a large number of WPP’s operating companies and 2,000 employees into the top seven floors of the Waterfront Innovation Centre at the city’s iconic ‘Sugar Beach’. HH Angus provided engineering consulting services for this 250,000 ft2 tenant fitout project. WPP is the anchor tenant for the Waterfront Innovation Centre.
The fitout included raised floors for underfloor HVAC systems and is targeting LEED Platinum certification. On each floor, the design features a café, hub and IT equipment room, with one single Main Communications Room.
The 8th floor has a custom production area with very specific acoustic requirements. Our mechanical team worked closely with the acoustical consultant to provide a design that meets the strict acoustic requirements for video and audio production and recording. This was achieved through careful placement of fan-powered boxes equipped with silencers. The production area includes multimedia studios, photo studios and a print lab. Lighting control for these rooms is enhanced with tunable lighting, allowing users to adjust the colour temperature in real time.
The 10th floor is the client-facing floor and includes meeting rooms with fully-integrated AV, smart lighting control, open ceiling design concept (industrial design), a large point-of-sale catering kitchen with back of house facilities and an outdoor terrace.
Our communications team designed several interconnecting fibre risers to provide the client with the most cost effective solution and full redundancy to meet their current and future needs, and to ensure the system will continue to operate in the event of external critical failures.
