Hear tales from the trenches regarding ventilation approaches within the context of the Passive House certification standard. This standard has set a high benchmark for low-energy buildings and is widely known as the most rigorous energy efficiency standard currently available. However, the ventilation systems and their interfacing with heat pumps are relatively new to the industry and need to be executed correctly.

In the Northeast, we have the benefit and burden of a large stock of uninsulated masonry buildings of various typologies and conditions. Leaving these buildings as they are is untenable with the global effort to reduce carbon emissions, and will not address climate shifts, the fabric of community, or the health of occupants. We will explore insulating from the interior, exterior, or both.
