After a major refurbishment to event spaces and 219 guest suites at Toronto’s 17-storey Park Hyatt Hotel, the building’s managers also wanted to improve its heating efficiency and reduce its energy consumption.

The managers collaborated in this effort with locally headquartered consulting engineering firm The Hidi Group—more specifically, with its commissioning business, HRCx, which works with building owners, architects, engineers, contractors and operations staff throughout projects’ design, construction and occupancy phases.

The hotel site’s flow requirement specification was 600 gpm at a 75-ft head. Local manufacturer Armstrong Fluid Technology recommended replacing one of two existing pumps with a Design Envelope Permanent Magnet (DEPM) vertical in-line pump, so as to provide a head-to-head efficiency comparison.

With its high-efficiency design, the pump promised to deliver the required output with just a 15-hp motor—and both the smaller pump and motor would reduce capital costs. The hotel’s managers agreed to try out the newly developed pump, which at the time was not yet available to the general public.

Pump Systems Interfacing (PSI) of nearby Markham, Ont., performed the installation. Armstrong then started up the new pump and completed commissioning in May 2022.

The commissioning report showed the pump reduced average energy consumption by 60%, from 1.66 to 0.66 kW, and promised annual energy savings of $17,626. Related average carbon dioxide (CO2) emissions were reduced by 16,452 kg (from 96,283 to 80,831 kg).

There were no on-site challenges during the project. Installation, start-up and commissioning all proceeded smoothly. The Park Hyatt Hotel’s facilities manager, after receiving the results of the commissioning report, asked the executive team to invest further in fluid pumping technology.
