In the quest to optimize comfort, efficiency, and architectural design, professionals struggle with thermal-bridge-free detailing, they closely examine the air barrier continuity and triple-check the window placements in the PHPP – but the ventilation? Too often, there is a lack of appreciation for the profound impact ventilation has on a building’s energy balance and the design freedom that results from optimized ventilation systems. Ignore it no longer. Learn about the Passive House Institute’s criteria for ventilation units and systems certification. Understand why, scientifically, it is as it is, and the results when implemented on a large scale.  Ask questions and use the hour to dive deeper into the discussion with the presenters.
