Our Team

Jack began his building science journey in 2004 with hands-on experience in low-rise residential construction, mastering a variety of skills, including framing, drywalling, and installing Hi-Velocity ductwork. This hands-on experience ignited his passion for energy-efficient housing, leading him to earn designations as a HRAI Residential Air System Design Technician and Residential Hydronics Design Technician. 

20+ years later, Jack is now regarded as one of Canada’s most trusted experts in energy efficient housing. In addition to his role as a Board of Director at the Canadian Associations of Consulting Energy Advisors, he actively contributes to the industry by serving on:
