Bay Adelaide Centre, Phase 1 West Tower
The Bay Adelaide Centre Phase 1 West is a large downtown Toronto office tower. HH Angus was involved in the design and tendering of elevating devices in this new 51-storey development.
Elevating systems include 28 passenger elevators, 2 service elevators and 2 escalators. The passenger elevators have rated speeds ranging from 3.5 m/s (700 fpm) in the 5-car low rise bank to 7.0 m/s (1400 fpm) in the 8-car high rise bank.

Tindall Playing Field Relocation & Parking Structure
“The opening of Tindall Field is the first step for Queen's Athletics in moving towards our vision of becoming the best in Canada.”
– Leslie Dal Cin, Director of Athletics and Recreation, Queen’s News Centre Sept. 2008
Kingston, Ontario’s first outdoor artificial playing surface, Tindall Field at Queen’s University, was developed as a two-level underground parking structure and a running track and Soccer/Football Playing Field. The roof of the parking structure forms the base of the playing field, and includes a playing field storm drainage system that directs the storm water to a large cistern for flow control into the municipality’s storm drainage system. The field is surrounded by a 3-lane rubberized track.
Resolving light pollution issues was critical, given the proximity of the field to a student residence and the campus observatory. Lighting consisted of pole-mounted luminaires on each side of the playing field. The light distribution was controlled by designing shields for the upward lighting component and reflectors with cut-offs to reduce light distribution at the edge of the playing field.

341 Bloor Street West, Senator David A. Croll Apartments
“The system brings enormous value to the facility. Not only does it increase the emergency power load to near peak load, but also it reduces emissions and eliminates transmission losses, thus reducing the need for expanded power generation.”
- Paul Isaac, Principal in Charge, HH AngusThe Senator David A. Croll Apartment building, formerly Rochdale College, is a typical multi-unit residential building managed by the Toronto Community Housing Corporation.
This 335 kW combined heat and emergency power (CHeP) project was built to avoid the cost of replacing a diesel generator, with a significant saving of $300,000. Conventional emergency on-site generation uses dedicated equipment that is rarely operated, yet has a very high capital cost (known as a ‘stranded asset’). HH Angus converted this stranded asset to provide an economic benefit to the facility. The benefit comes from recovering heat so that the overall efficiency rose from 33% to 83%, as well as the use of natural gas, which is cheaper than diesel.
The new generator produces enough electricity for the entire building load on most days. The heat generated by the engine is captured and used to heat the domestic hot water system and building spaces, thereby producing a highly efficient use of the fuel - greater than 90%!
The most important benefit for the building’s occupants is the increased emergency power load capabilities. Instead of powering just a minimum of elevator and emergency lighting services during power outages, the CHeP system provides a power load that runs all regular systems, including heating and air-conditioning systems.

Welder Water System, Car Assembly & Truck Plants
HH Angus designed the Welder Water System for the car assembly and GMT 800 C/K Truck plants in Oshawa. These systems provide cooling water for all the robot welders, circulating cooling water to the tips of the welders to prevent overheating.
C/K Truck Plant
This plant’s welder water system consisted of a cooling tower system and cooling distribution system. The pumps re-circulate tower water from the indoor sump through heat exchangers and up to the cooling towers. The cooling tower system featured five main components: Cooling towers, indoor sump, recirculation pumps, plate heat exchangers and centrifugal filter units.
The two vital conditions that had to be maintained were temperature and differential pressure. A temperature sensor on the hot side of the heat exchanger (closed loop side) controlled the staging of the cooling towers and the speed of the variable speed drive cooling tower fans. Pressure differential transducers located at the index runs staged the cooling water pumps to maintain differential pressure. The welder tips are extremely sensitive to differential pressure, so very tight pressure tolerances have to be maintained at all times.
Car Assembly Plant
In the Car Plant, renovations required the relocation of the welder water system, together with the supply and installation of three new cooling tower pumps and three new circulation pumps.
The three cooling tower pumps were each 100 horsepower, electrically driven, and with a flow rate of 2670 US gallons per minute. The three circulating pumps were each 150 horsepower.
The distribution piping system extended over 3,000 feet, serving welding robots throughout the car assembly plant. The heat transfer, between the circulating (robot cooling) water and the tower cooling water, takes place in four plate-type heat exchangers.

Fuel Cell Building
This building was designed to house Ford’s ‘Fumes-to-Fuel’ technology, which converts toxic volatile organic compounds (VOCs), generated during the painting process, into electricity that powers the plant’s operations.
The Oakville system began with a 120KW internal combustion engine that was installed as part of this project. Ford had plans to add additional power generating equipment.
HH Angus served as Prime Consultant for a new, state-of-the-art, 10,000 ft2 building to house a patented process for the capture of VOCs from spray booths.
This engineered industrial building, with a height of 35.5 feet, was constructed adjacent to the existing Ford plant, but is not linked to the plant. The building contains a public viewing area for Ford’s green energy system, a training room, offices, warehouse and washrooms. All public spaces were air-conditioned. A steam boiler provides heating for both the fuel cell process and the building. The electrical feed to the building supports both the process and building. It was connected to an existing electrical substation located inside the existing plant.
As Prime Consultant, we were responsible for all architectural, engineering and structural disciplines for the building, as well as site services and associated utilities for the fuel cell process to function properly.
