Joanne Sawatzky (BTech, MSc., CPHC, LEED® AP BD+C) has worked in the green building sector throughout her whole career. She decided on a career in architecture when she was in the seventh grade, which inspired her to pursue a Bachelor in Architecture + Building Science, and a Masters in Energy Efficient Building. As Light House’s anchor employee since 2007, Joanne has led many of Light House’s most challenging and innovative projects, including The Whistler Athletes Village, The Foundry, and Telus Gardens Office and Residential. She works closely with a wide range of clients—from developers to architects—on implementing green building projects, technical policy development, contractor training, and post occupancy evaluations.

Joanne has two decades of experience working in design, construction and operation on commercial, residential, and healthcare building projects across Canada. She is the first female BuiltGreen Canada High Density Verifier and has taught contractor training through the Vancouver Regional Construction Association (VRCA). She has also taught and mentored building science students in the Architectural Science Department at Ryerson University.

When asked about her proudest accomplishments, she’ll tell you that getting a project—any project—complete, and seeing her clients get what they need, is the best feeling. To Joanne, sustainability is about making small but measurable changes that add up…and lead to better buildings and a better quality of life.
