Component Spotlight Achieving Passive House Levels Of Airtightness Many passive house design principles are invisible and they are designed into the fabric of the building itself, such as a high level of airtightness. with this in mind, coltraco ultrasonics has developed portascanner® airtight, the world’s first micro air leak detector, which uses ultrasound only. Many passive house design principles are invisible and they are designed into the fabric of the building itself, such as a high level of airtightness. with t.

As awareness of airtightness metrics has increased, the average performance of new homes in ireland has risen sharply. the unpublished 2005 energy performance survey of irish housing found that new homes built around the turn of the millenium had an average airtightness of 11.8 m3 hr m2 @ 50 pascals. Using pre fabricated airtight components for windows, doors, and service penetrations can help maintain the integrity of the air barrier. 3. renovation projects: retrofitting existing buildings to passive house standards can be challenging due to the difficulty of achieving airtightness in older structures. however, with careful planning and. Passivhaus airtightness (n 50) ≤ 0.6 h 1 @ 50 pa note: the limiting value of 0.6 h 1 @ 50 pa should be used as the default design air tightness value in all preliminary passive house planning package (phpp) calculations until a verified pressure test reading is available. it is important to note that achieving a heating.
