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.

Pickering Casino Resort

The Pickering Casino Resort is being built in two phases - the first includes gaming and dining facilities, and the second features an entertainment venue and hotel.

HH Angus was engaged to provide electrical engineering and design services and supporting infrastructure for security, AV, IT/communications, and lighting for this 330,000 ft2 greenfield development. When complete, the complex will include a 250-room hotel, a gaming facility accommodating approximately 2,350 slots, 100 gaming tables, 167 Live Dealer Stadium Gaming terminals, a variety of dining options, retail space, and a 2,500-seat multi-purpose performance venue.

This project was fast tracked with a very aggressive schedule. As the site previously was a field, our key challenge was to lay the infrastructure in place to support a world-class casino (power, telecom, traffic, lighting, water, civil engineering, etc.). We accomplished this task with the help of our design assist partner Guild Electric. HH Angus and Guild worked very closely from Day One to represent the client at all levels of design. Together, we approached the utility companies, vendors, and supply chain to ensure we could achieve the aggressive schedule.

Among the key electrical engineering elements are:

  • Encapsulated below-grade generator room and main electrical distribution
  • Campus electrical distribution system is fully concrete encased below the casino floor. This required a high level of coordination prior to the concrete pour
  • Intelligent and fully addressable lighting control system. Utilized for aesthetics, security, and life safety
  • Strategic early works planning and coordination with electrical utility to allow temporary power and permanent power to derive from the same service; this was a significant cost saving for the owner
  • Emergency power distribution supplemented by uninterruptible power supplies ensure the casino and critical services can continue to operate independently of the utility grid for a prolonged period of time
  • 2000+ security cameras and necessary IT infrastructure was designed to support access control, intrusion, CCTV, panic duress, coordination with OPP and AGCO.

Sustainability features

Parking amenities include a solar carport and integrated EV charging stations. HH Angus worked with VCT Group on these features, designing the infrastructure to allow the photo voltaic system to tie into the electrical network. The surface parking area will accommodate approximately 1,675 cars and the parking structure will provide for another 3,000 cars.

Customer experience

Creating a seamless and luxurious customer experience was a key success factor in the project, and Angus Connect worked closely with the owner on the IT systems, which will support the customer experience and enhance the security and efficiency of the casino operations.

Sunnybrook Health Sciences Centre 

Garry Hurvitz Brain Sciences Centre

“The Garry Hurvitz Brain Sciences Centre will revolutionize the future of brain health like never before. It will be a global hub of innovation that will accelerate the discovery of the next generation of treatments, prevention and possible cures to the world’s most debilitating brain conditions.”*

HH Angus is providing mechanical and Electrical engineering for this 118,285 ft2, three-storey above-grade structure. The building will be constructed within a dense urban campus between existing building wings and will be connected to the main hospital circulation spine, with flexibility provided to accommodate future expansion.

Our project scope includes:

  • Expansions to existing infrastructure, including a new 1600 ton centrifugal 4160 volt Chiller;
  • A major modification to the Emergency Power System to provide emergency power to at least one chiller and the chilled water distribution system;
  • New steam service and high voltage electrical services to the new building from the existing power plant
  • A significant Information Technology service and distribution system, including fibre cable connections to the hospital’s existing Core Distribution Rooms, new network hub room components, including network switches and all on-floor cable/outlet systems
  • Significant expansions to the existing Building Automation System, central electrical metering system, fire alarm system, security system, CCTV system, nurse call system and Code White systems.

The new building includes:

  • Mechanical and electrical services in the basement designed to provide for the current construction, as well as a possible future four-storey addition
  • Adult In-Patient Mental Health Unit and PICU Unit on the ground floor, both with access to outdoor courtyards
  • Child & Youth Mental Health Unit
  • Circadian Study Unit on 1st Floor
  • Neuromodulation Treatment Unit, Enhanced Examination, Teaching and Research units on the 2nd Floor

The Sunnybrook M&E services tunnel is a complicated space. Because this is a new building on an existing site and represents a major expansion to the campus, connections to existing buildings with multiple M&E ties are required.

Among the interesting challenges of this project was obtaining the required mechanical and electrical services spaces. The larger they became, the more they impacted the functional programming and the project budget. Compromises were made regarding ceiling heights, and collaboration with facilities management staff helped in obtaining the space required.

As well, the main entrance “glass box” presented some unique mechanical design challenges. Ventilating a two-storey structure with no exposed services required innovative engineering, including ventilating from below.

In designing the building systems for this project, our team devoted special attention to providing a living space that offers an excellent therapeutic environment for the brain-injured patient while, at the same time, ensuring the safety of both patients and staff; in particular, preventing any opportunity for self-harm by patients.

Within HH Angus’ lighting scope, LED linear fixtures set the stage for modern lighting aesthetics used throughout the new, state-of-the-art centre, including corridors, inpatient bedrooms, the main triple height lobby, and the exterior soffits. The efficient LED non-glare, dimmable lighting will be connected to a centralized lighting control system. The provided lighting management software enables facility managers to monitor, maintain and control the entire networked lighting control system, including schedules and energy usage.

Bloor-Dundas District Energy Feasibility Study

HH Angus was engaged to conduct a feasibility study for a Low Carbon District Energy Plant serving a new, three million square foot mixed use residential and commercial development along Bloor Street in Toronto.

The full development is being implemented in several stages over ten years. HH Angus provided Prime Consultant and Mechanical and Electrical Engineering services, and developed a conceptual framework for the study.

The study considered a combination of traditional and renewable energy sources to provide heating and cooling, reviewing a range of options that included the following:

  • Condensing hot water boilers, efficiency up to 90-95%
  • Centrifugal water-cooled magnetic bearing chillers
  • Water source heat pumps (heat recovery chillers) to provide simultaneous cooling and heating
  • Air source heat pumps to provide simultaneous cooling and heating
  • Ground source heat pump system
  • Ambient loop system
  • Sewer heat recovery system
  • Combined Heat & Power (CHP) system to generate power using a gas-fired generator and to provide heat using waste engine heat, with overall generator efficiency up to 80%. CHP can be used as backup power source and to reduce energy cost during periods of peak cooling and electrical demand.

HH Angus conducted calculations of estimated heating, cooling and electrical loads, plus energy consumption for future development, establishing options for the arrangement of the District Energy plant, including provision for expansion to provide heating and cooling to future developments in the neighbourhood.

Our study scope also included tentative District Energy plant layout and area requirements, capital budget, operating costs and NPV estimates for each option, as well as analysis of results and corresponding recommendations.
