Join us to learn about Air Admittance Valves and a new way to do Drain Vent Calculations!

Welcome to the all-new bi-monthly Passive House Technical Group! Formerly known as the PHPP User's Group, this event will now feature deeper dives into a broader range of Passive House topics and various energy modelling software. If you have a topic request, or issue you'd like help resolving, please email us.

The event will feature two presentations: 

Sherman Wai, RDH Building Science, will speak on the new Drain Vent Calculator from PHI, and how it differs from the old version, and then Sandra Rohler, Cornerstone Architecture, will speak with Rod Yeoh, DIALOG Design, on their Air Admittance Valve work on the Little Mountain Housing Coop.
