Tim is a senior mechanical engineer and project manager in HH Angus’ fast-paced Commercial Division. Since joining the firm in 2013, he has consistently demonstrated strong technical abilities and a dedicated work ethic, often putting in extra hours to ensure clients’ work is completed with the utmost quality and care. He has also been instrumental in developing calculation tools for HH Angus, including HVAC piping and ductwork sizing tools, ASHRAE 62.1 calculation tools and more. Tim is also member of ASHRAE and enjoys the distinction of being the first HH Angus WELL APTM-accredited staff member.

Tim expresses his passion for engineering by developing standards and protocols through his work. He is a member of the HH Angus sustainability committee, the standards committee, and the calculation tools committee. Tim is currently working on overhauling HH Angus’ drafting standards to be implemented in the REVIT platform. He is also developing template control sequences and diagrams based on the ASHRAE 36 High performance Sequences of Operation for HVAC Systems. Tim regularly provides instruction and training for colleagues, including both new and experienced engineers and designers, and volunteers in University of Toronto’s Engineering & Strategies Practice course, working with students to provide real-world context to their studies.

We warmly congratulate Tim on this significant honour that publicly recognizes his outstanding efforts and qualities – well done!

“Azure’s International AZ Awards recognize excellence and innovation in architecture and design, and celebrate the world’s best projects, products and ideas.”

This international design competition annually selects winners in the categories of design, architecture, landscape architecture, urban design, experiential graphic design, interiors, concepts, student work and social good/environmental leadership. The 2022 awards saw Toronto’s Mirvish Village redevelopment project winning in the Urban Design Vision category. Click here to read more about the Mirvish Village AZ Award.

Award-winning Redevelopment

Mirvish Village is rising on the site of ‘Honest Ed’s,’ a much-loved discount store that was at the heart of Toronto’s Mirvish Village neighbourhood for almost 70 years. The redevelopment is currently under construction and spans 4.5 acres, creating nearly 1 million ft2 of purpose-built rental housing and retail space.

Mirvish Village has a focus on sustainability and affordability. To achieve this, the redevelopment is incorporating a district energy system and micro-grid that will offer a resilient means of thermal energy, power, and emergency power, enabling the project to meet LEED platinum and the City of Toronto’s Tier 2 Toronto Green Standard requirements. 

HH Angus’ Role

Our Energy Division team worked closely with Creative Energy Developments to provide mechanical and electrical engineering services for the Village’s central utility plant, which includes a combined heat and power plant (CHP), a boiler plant, and a cooling plant. The CHP plant includes an 800 KW generator set with auxiliaries and heat recovery system. The generator is expected to run continuously to provide power to the complex.

Heat recovery consists of two systems: high temperature to provide heat to buildings, and low temperature to provide additional heating for a winter snow melting system and swimming pool heating. The boiler plant includes four condensing hot water boilers, with the option for two additional boilers in future. All boilers have an output of 3.1 MW.

The cooling plant includes two water-cooled chillers, operating at 1200 tons each. One is a magnetic bearing chiller with variable frequency drive (VFD), and the other is a centrifugal chiller with VFD. As well, two rooftop cooling towers at 1200 tons each have been installed. 

Central distribution piping from the plant will provide hot water and chilled water to multiple energy transfer stations, with heating, cooling, and domestic hot water heat exchanges for each building within the complex.

A photo-voltaic solar system will have a capacity of 103KW, 480V. HH Angus provided direction for locating the installation, coordinated with the PV supplier for modeling the panel direction and angle for optimal PV output, developed technical connection requirements with Toronto Hydro, and identified requirements for parallel generation with the central utility plant. Our scope also included developing thermal and electrical metering strategies within a microgrid system, and design of operation for gas-fired emergency generators in electrical peak shaving mode.

Hospital Substation Gas-insulated Switchgear

Located in Toronto, ON, Sunnybrook Health Sciences Centre is a full-service hospital with over 1,300 beds, making it the largest regional trauma centre in Canada. Through its partnership with Veterans Affairs Canada, it is home to more than 500 veterans. With a main campus of approximately three million square feet, Sunnybrook is redeveloping its existing main outdoor electrical substation in its
entirety. The project incorporates several innovative features, including using 38 kilovolt class gas-insulated switchgear, new power transformers with increased capacity, and multiple civil upgrades. In addition to a decreased footprint and reduced maintenance requirements, the new switchgear interfaces with a networkbased monitoring and control system. In this photo, the switchgear undergoes indepth factory acceptance testing in Frankfurt, Germany.

Hovering Autonomous Underwater Vehicle

In fall 2017, Cellula Robotics Ltd. successfully demonstrated its Imotus-1 Hovering Autonomous Underwater Vehicle. During a week of testing at a local pool facility, Imotus-1 navigated using proprietary Simultaneous  Localization and Mapping (SLAM) algorithms and was shown to hold station, waypoint track, manoeuvre around obstacles, and dock to an underwater charging station. The docking demonstration was sponsored by Ocean Networks Canada; development of SLAM was made possible through funding from the National Research Council’s Industrial Research Assistance Program. In 2018, Imotus-1 will be used by Cellula in the North Sea for commercial survey and inspection work inside the structural legs of an offshore platform.

Novel Polystyrene Recovery System

A.H. Lundberg Systems Limited of Vancouver designed and supplied a modular distillation system for Polystyvert for its polystyrene (Styrofoam) recycling demonstration plant in Montreal. In a novel patented process, an essential oil is used to dissolve the polystyrene at the user site, thereby drastically reducing the volume and subsequent transport costs to the recycling plant. Following recovery of the polystyrene using a liquid hydrocarbon, the distillation system separates and recovers the essential oil and hydrocarbon for reuse in the process. The module was fabricated and assembled by Acier St-Michel in Laval, QC. The plant is scheduled for commissioning in May 2018.

You might have heard about some new technologies in healthcare and other industries lately, or had colleagues ask about technologies they’ve heard of or seen in other hospitals. The Angus Connect group helps our clients understand and evaluate these technologies to identify those which provide the best value and strategically align with the goals of the hospital, then assist with planning and specifying the implementation of the selected systems. Click to Download complete Article >
