Please join us for the June Passive House Group Meet Up in Toronto! Please register for this free event here.

Successful Passive House projects rely on attention to detail in both planning and execution. At this meeting, Greg Leskien of Zon Engineering and Jesse Matthews of The Fourth Pig Green and Natural Construction will discuss their experiences from both the design and construction perspectives of their Passive House projects, with a focus on how to successfully translate Passive House designs to Passive House buildings.

6:30 PM – 6:50 PM: Greg Leskien, C.E.T., C.P.H.D., Level II Thermographer. Vice President, Design and Field Services at Zon Engineering Inc.

Greg will provide an overview of his experience as a CPHD, and his work with Zon on multiple Passive House and net-zero projects across Ontario, including the approach to "active" detailed design and construction support.

6:50 PM - 7:10 PM: Jesse Matthews, Certified Passive House Tradesperson, PHIUS Certified Builder. Carpenter, Fourth Pig Green and Natural Construction.

Jesse will share lessons learned working as a Passive House Tradesperson, discuss the role of the Airtightness Champion or “Air Boss” on Passive House projects, examples of successful on-site problem solving.

7:10 PM - 7:30 PM: Greg and Jesse will discuss their experience on multi-unit affordable Passive House projects currently under construction, the Passive House Designer/Tradesperson relationship, and opportunities for collaborative problem solving between the CPHD and CPHT.
