Passive House Accelerator is a catalyst for zero carbon building and a hub for sharing innovation and thought leadership in Passive House design and construction. In this webinar, Mr. Dobrowolski and Major Hornung discussed the importance of airtightness in Passive House design and how Portascanner® AIRTIGHT can help achieve Passive House levels of airtightness.

Portascanner® AIRTIGHT is the world’s first micro air-leak detector that uses ultrasound technology to detect even the smallest air leaks in the building envelope. This device is a safe and non-invasive way to achieve Passive House levels of airtightness and improve the energy efficiency of a building.
