Marianne Touchie


Marianne Touchie joined the University of Toronto as an Assistant Professor in July 2016 and and received tenure in 2022. She is jointly appointed in the Departments of Civil & Mineral Engineering, and Mechanical & Industrial Engineering.  She completed her BASc (2009) and PhD (2014) in the Department of Civil Engineering at the University of Toronto.  Upon completion of her PhD, Marianne became the Building Research Manager at the Toronto Atmospheric Fund and was also a Postdoctoral Fellow at the University of Toronto.

Dr. Touchie’s research focuses on improving the energy performance and indoor environmental quality of existing buildings to make them more comfortable, healthy and sustainable through comprehensive retrofits.  This work includes monitoring and characterizing building energy performance, environmental parameters and occupant perceptions to determine the influence of potential retrofit approaches, both active and passive.  Much of her research has been in the multi-unit residential sector and particularly social housing buildings.

Dr. Touchie is also President of the Building Science Specialist Board of Canada and former Chair of ASHRAE Technical Committee 2.1 Physiology and Human Environment.  She teaches courses in Building Science, HVAC Fundamentals and Building Performance Assessment.
