Toronto Public Library
Wychwood BranchThe Wychwood Library is one of Toronto’s oldest libraries, built in 1915/16 and listed among Toronto's designated Heritage Properties.
HH Angus provided mechanical and electrical engineering for the renovation and expansion of the Wychwood Branch of the Toronto Public Library. Following a feasibility study that identified the desired expansion was possible, the facility expanding from 6,381 ft2 to 15,000 ft2, with mechanical and electrical systems replaced throughout the facility, including new incoming electrical and communication services.
The project included interior and exterior renovations to building structure, mechanical and electrical systems and a complete redesign of the floor space. Necessary facility upgrades included replacing flooring, millwork, furniture, elevator and heating, ventilation and air condition (HVAC) systems and equipment, building systems, and building envelope repairs.
The redesign of this heritage facility created room for approximately 2000 ft2 of seniors’ program space as well as innovative space for youth, both of which were needed in the community.

TD Bank
Living Roof“The Green Council [tenant representatives] has made it clear, through a commitment to action, that sustainability is a core value of TD Centre tenants.”
David Hoffman, then-General Manager. TD Centre
At the TD Centre’s iconic towers in downtown Toronto, TD Bank’s Living Roof offers both environmental benefits and some much-needed green relief from the usual hardscape views had by occupants of the Centre’s towers. It covers 22,000 ft2 and is planted with creek sedge grasses, a hardy semi-evergreen native species tough enough to survive the extremes of Toronto’s climate. Annual energy savings from the green roof are approximately $23,000. This is achieved by reducing summer cooling and winter heat loss by 25%.
HH Angus provided mechanical and electrical engineering for the green roof installation and irrigation system, as well as the project’s preliminary Feasibility Study. To avoid over-watering, the irrigation system features a sensor that shuts down the irrigation system when it rains. This sensor also reduces irrigation when the water received during previous rainfalls or irrigation has not yet evaporated.
In order to evaluate the requirements for mechanical and electrical design for the irrigation system, the ceiling plenum for the single story building below had to be surveyed. The storm water drainage system was original and would need modification and updating. The existing plumbing was modified to allow connection of the new irrigation.
Installation of dedicated electrical circuits and automated controls was required in order to operate the self-draining irrigation system. The controls were ceiling mounted with remote computer access. Rain spray heads, valves, head sensors, pattern nozzles, valve boxes, and stainless roof drains were incorporated.
Before the design could be executed, rainwater calculations were carried out based on Environment Canada data, along with spreadsheets detailing storm water run-off. These calculations assisted in sizing the storm water piping and locating roof drains and spray nozzles.
A roof leak detection system was also designed, along with a new soil pipe vent stack through the Pavilion roof, and a gooseneck conduit for rooftop wiring. A new replacement filter rack was added to the roof air vents.

365 Bay Street, 3 Floor Fitout
This 12-storey building is located in the heart of Toronto’s business and financial core. Constructed in 1960, the mechanical and electrical infrastructure was outdated and major redistribution and rework of the existing systems was required in order to suit the new tenant fitout.
HH Angus was engaged to provide fitout services for this commercial office renovation project. Our scope included mechanical, electrical, lighting and communications engineering design for renovations to three floors of office space for a standalone corporate finance and tax law firm.
The 8th floor consisted of renovations to 7,000 ft2 of client-facing space, including a universal washroom, meeting rooms, reception and welcome areas. A large existing boardroom was converted into multipurpose meeting space. This conversion required additional ventilation in order to accommodate up to 50 people.
A new build out included open and enclosed office space to accommodate future growth. A new universal washroom was also provided as part of the updated layout.
Extensive demolition was required in the central part of the floor plan to accommodate the new layouts. Construction took place during working hours; therefore, special planning and design were needed to accommodate critical areas and workstations during construction. Hoarding was required to separate these areas and ensure the safety of occupants. The project schedule was very aggressive.

Cadillac Fairview
Toronto Dominion Centre
HH Angus has been working at this site since the earliest days of the Toronto Dominion Centre, Canada’s first skyscraper. We provided complete mechanical and electrical engineering services to the Toronto Dominion Bank and Cadillac Fairview (CF) in the construction of the first four towers, which total 5,600,000 ft2.
Those original iconic towers (now six) and the interconnecting below-ground shopping concourse comprise office space, underground parking and a retail and restaurant complex in the heart of downtown Toronto.
With the certification of 95 Wellington as Gold Level WELL Core, the entire TD Centre is now WELL certified, the largest real estate complex in Canada to have achieved this designation.
We have been involved in numerous technical infrastructure upgrades, including the installation of heat exchangers to the cooling plant in order to link to the Deep Lake Cooling system. We have provided detailed redesign of the service floors so that the space previously occupied by the cooling plant can be upgraded.
The Toronto Dominion Tower, the tallest at fifty-five stories, employs a perimeter induction heating and cooling system; all other buildings, which were designed later, employ variable air volume systems. Each building has a number of air handling plant room floors located approximately every twelve floors. This helped to minimize the size of individual pieces of equipment and the on-floor shaft sizes required.
Steam is used as the prime heating and humidification source for the Centre. Supplied from the Enwave District Energy System, the steam demand is rated at more than 70,000 kg/hr. The cooling load of over 49,000 kW is supplied by the Deep Lake Cooling system.
As part of the ongoing evaluation and revision of existing mechanical and electrical systems for this property, CF has invested in a new luminaire and ceiling combination. This investment provides tenants with base building illumination of a high quality while reducing the total lighting power density for building operations. This new luminaire system, in combination with accurate metering and appropriate building automation, is contributing to CF’s success in meeting and exceeding the ASHRAE 90.1 energy standards.

A lasting impression
TD Centre Heritage Designation:
The TD Centre in Toronto was designed by Ludwig Mies van der Rohe and, from 1967 to 1972, was the tallest building in Canada. A leading example of the International style, the TD Centre altered the city’s skyline while influencing many subsequent buildings across the nation.*
Toronto Dominion Bank
TD 23
TD Bank Group was awarded the world’s first WELL™ Gold certification for their TD23 pilot project. This ground-breaking achievement was a milestone in the development, growth and expansion of the WELL™ Certification program.
HH Angus is proud to have participated in the first project to be certified WELL Gold by the International WELL™ Building Institute (IWBI) through version 1 of its WELL Building Standard (WELL). We congratulate TD Bank Group for the success of their pilot project – the 23rd Floor of Tower One at the Toronto Dominion Centre. The project provided us with an excellent understanding of the WELL™ certification process.
The WELL™ Building Standard is the first of its kind to focus on the health and wellness of building occupants. It identifies performance metrics, design strategies and policies that can be implemented by owners, designers, engineers, contractors, users and operators of buildings. We believe the Standard has the potential to be widely embraced and adopted in conjunction with current LEED practice, so we were delighted to be involved with WELL™ in its early stages.
