The Barclays Bank building was singled out for its robust design, which featured a high standard of sustainability and energy efficiency, rare attributes for a high technology building. It also earned the UK's "Breeam Excellent" rating, comparable to LEED® Gold.
The tower consists of a main operations facility, data centre and trading floor with 32 floors above grade, 1,000,000+ ft2 of computer centre, trading floor and high technology office space. HH Angus provided an overall electrical and mechanical design that ensures there are no single points of failure.
Mechanical services were designed to achieve high quality practical solutions for the high cooling loads, while ensuring flexibility for subtenants and office churn. The systems boast dual risers and split plant for the majority of services in order to provide continuity of service for maintenance or in the event of failure.
Electrically, the building has an extremely resilient service provision with dual incoming electrical supplies, 8 MVA of UPS power and 12 MVA of generator power available. The design included dual 11 kV service entrance, a dual 11kV APS systems (12MW), a 2(N+1) UPS topology (8x800kW). All electrical services were provided in a dual riser and split plant format, providing continuation of service under failure or maintenance.

Ensuring team coordination
Close coordination with the architectural, structural and other consultants was needed, in order to integrate the various mechanical and electrical systems into the station structure. Services were extensively embedded.
Collaborating for successful delivery
Engaging the key stakeholders from the client’s design and operations teams, the design team and project management team was instrumental to successful design implementation. Our design was highly detailed, to ensure the installation contractors could both bid the project with confidence and construct it successfully.
Hydro One
Grid Control Centre
Hydro One’s world-leading Grid Operations Centre involved construction of a greenfield building housing an Integrated Transmission Operations Centre as part of the distribution network.
The highly secure critical facility required special design features to enable it to be fully functional under any circumstances, including a post-disaster situation, and incorporated highly reliable and maintainable electrical and mechanical systems.
The main control room was fully hardened against both natural and man-made disasters, and capable of long term independent 7/24 operation . It was constructed to have a high quality environment with “very quiet” dual redundant air conditioning systems with static electricity and humidity control, dual UPS power supplies to each control desk and projection screen, and high quality glare-free controllable lighting sources, with all systems capable of long term independent post-disaster operation.
Other aspects of the project included:
- High quality security, CCTV, and access control
- Dual redundant UPS system with hot transfer capability and maintenance bypass features
- Redundant diesel generators including dedicated fuel storage and pumping system, with the capability of connecting an additional portable unit
- Redundant 44 kV utility supplies originating from transformer stations with automatic change over and dual step down transformers and secondary 600V Switchboards
- Redundant mechanical support systems, with mechanical systems fully enclosed by the building structure

Carlu Corporation, College Park
The Carlu
After sitting shuttered, run down and neglected for almost 25 years, this landmark venue underwent a comprehensive two-year renovation that brought the entire seventh floor back from the brink. Now designated a National Historic Site, the former Eaton’s store on College Street in Toronto boasts an event venue fully restored to its 1930s splendour, and worthy of the original vision of Lady Eaton.
Renamed in honour of the original architect, Jacques Carlu, the Art Moderne facility, which includes a grand foyer, auditorium and the Round Room restaurant, was in desperate need of refurbishment and renovation. The historical significance of the space was not lost on the new leaseholders, or the Toronto Historical Society.
HH Angus’ role as mechanical, electrical and communication engineers and lighting designers, was coordinated through our Tenant Engineering group. The project differed significantly from a typical renovation. HH Angus worked diligently to preserve and re-create the appearance of the 1930s interior. Mechanical and electrical systems were modernized and seamlessly integrated into the facility without detriment to its timeless charm.
The almost century-old façade now conceals new air handling, cabling, communications and sanitation systems. The Carlu has been transformed from a derelict relic of Toronto’s past into an up-to-date venue with historically accurate fixtures and fittings, new kitchen facilities, full climate-control and state-of-the-art audio, visual and wireless networked capabilities.
HH Angus’ creative engineering solutions overcame significant challenges posed by architectural constraints and complicated scheduling issues. Design sensitivity and engineering skill applied to this historical renovation helped make possible the rebirth of the stunning Carlu.

Respecting the vision
Track lighting accentuates art and art forms, and dimmer systems were replaced. To ensure historical accuracy, existing wall sconces were completely refurbished and revamped.
Queen’s University
Centre for Neuroscience
One of our key considerations in designing the laboratories at the Centre was to create a customized design to meet each lab’s specific research needs. HH Angus designers worked directly with researchers to understand their clinical needs to ensure the resulting mechanical and electrical fitout would support their research.
In addition to special considerations, the designs had to be flexible enough to suit the needs of future researchers working in the same lab space but in different disciplines. For example, we designed a high tech lab to measure very minute levels of electromagnetic fields in order to monitor brainwaves in subjects. Another lab was designed for research in acoustics, and yet another for optical research.
The research labs were designed as multipurpose facilities for non-human primates. Mechanical services were designed to meet all the requirements of the Canadian Council on Animal Care (CCAC). The ventilation system provides 100% outside air to all rooms. Temperature and pressurization are maintained by constant volume supply air with terminal reheat coils.
A dedicated indoor chiller with air-cooled condenser was installed to ensure year-round cooling for the facility in order to maintain consistent environmental conditions for research and for subjects. The MRI employs a dedicated closed cooling loop with city water emergency back-up loop. It was designed for use with both humans and non-human primates.
A later 4,275 m2 (~46,000 ft2) addition houses the new Cancer Research Institute. This brings together three internationally recognized cancer research groups: the National Cancer Institute of Canada’s Clinical Trials Group; the Queen’s Cancer Research Laboratory; and the Radiation Oncology Research Unit.
