Helen received her BASc and PhD from the University of Toronto. Her research investigated the impact of smart thermostat use on high-rise residential building performance. She is now an Assistant Professor at the Toronto Metropolitan University.
This project explored how replacing conventional programmable thermostat with smart thermostat could impact energy performance, thermal comfort and occupant behaviour in high-rise residential buildings.
