Central Utility Plant
Mirvish Village is reimagining a 4.5 acre section of Toronto’s Bloor/Bathurst neighbourhood, including the former site of the the iconic Honest Ed’s store, a beloved Toronto landmark. Featuring four high-rise, one low-rise and twelve heritage buildings, the mixed-use site will be home to more than 2000 residents.
HH Angus is working with Creative Energy Developments to provide mechanical and electrical engineering services for the Mirvish Village central utility plant, which includes a combined heat and power plant (CHP), a boiler plant, and a cooling plant. The CHP plant will include 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 will include installation of four condensing hot water boilers, with the option for two additional boilers in future. All boilers will have an output of 3.1 MW.
The cooling plant will include installation of two water-cooled chillers, operating at 1200 tons each. One chiller is a magnetic bearing chiller with variable frequency drive (VFD), and the other is a centrifugal chiller with VFD. As well, two cooling towers at 1200 tons each will be installed on the roof.
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.
The photo-voltaic solar system will have a capacity of 103KW, 480V. HH Angus is providing direction for locating the installation, coordinating with the PV supplier for modeling the panel direction and angle for optimal PV output, developing technical connection requirements with Toronto Hydro, and identifying requirements for parallel generation with the central utility plant.
We also assisted the client with a successful incentive funding application. Ultimately, the incentive was not applicable due to schedule changes, which meant the project could not meet the incentive deadline.
