University Health Network Saves on Energy
University Health Network (UHN), Canada’s largest research hospital, is reporting lower energy costs and indoor air quality (IAQ) improvements after adopting Aircuity’s intelligent building platform.
Aircuity monitors the indoor environment and instructs building ventilation controls to adjust airflow levels to optimal levels. A system installation in laboratories at the Princess Margaret Cancer Research Tower (PMCRT) have saved approximately Canadian $800,000.
Working with channel partner, AirGenuity, Aircuity replaced the facility’s previous exhaust fan application with one powered by variable frequency drives to allow fan speeds to be ramped up or down according to need. When the Aircuity platform detects any contamination in the exhaust plenum, fan speeds are increased until the air is clean again. This intelligent platform ensures not only energy savings but also a clean, healthy space for researchers and occupants of surrounding buildings in downtown Toronto.
While the exhaust fan application was being installed at PMCRT, University Health Network installed Aircuity to optimize supply and exhaust air in its Krembil Research Tower, incurring additional savings. Once Aircuity’s exhaust fan application was implemented, annual savings amounted to 1,550,000 kWh (equivalent to 160 houses in Ontario) and electric peak demand savings of 111.7 kW (equivalent to running 1,400 flat screen TVs simultaneously). This saved $200,000 annually. Coupled with savings from the previous Aircuity lab project in PMCRT, utility cost savings total $1,000,000 annually.
Ian McDermott, Senior Director for Research Facilities at UHN, says:
“We wanted to create the best research spaces possible but in an environmentally and fiscally responsible manner.
“We looked for innovative solutions and partnering with AirGenuity and Aircuity was absolutely the right choice.”
