Kelsey Saunders

Senior Building Scientist, KPMB Lab, M.B.Sc., CPHD, LEED AP

A senior building scientist with over a decade of experience, Kelsey Saunders joined KPMB in 2024 to foster the growth and impact of KPMB Lab. She holds a Bachelor of Architectural Science (Honours) and a Master of Building Science degree from Toronto Metropolitan University, is a Certified Passive House Designer, and is a LEED AP in Building Design and Construction.  

Before joining KPMB, Kelsey worked at RDH Building Science and Sustainable.TO where she played key roles as a building science consultant and project manager on Passive House, net zero carbon, mass timber, and prefabricated enclosure projects across typologies, from institutional and commercial to mixed-use and residential.  

Kelsey’s work over the past decade underscores the importance of building science in the delivery of excellent design. As a building scientist, she excels in helping architectural teams execute their designs through the lens of climate mitigation and adaptation, sustainability, durability, constructability, thermal efficiency, and air tightness. 

She is involved in several public and private research projects, including a recently published study of the embodied carbon impact of building enclosure systems in whole life carbon emissions to support early-stage decision making for low carbon design. 

Kelsey is also a sessional lecturer in the John H. Daniels Faculty of Architecture, Landscape, and Design and the School of the Environment at the University of Toronto teaching courses on building science and environmental design. 

Additionally, she is on the Board of Directors of the Ontario Building Envelope Council and chairs the Council’s Membership and Outreach Committee.

“Building science enables us to craft resilient, durable, low-carbon buildings that meet our design intentions and contribute to social wellness and climate resilience.”
