【 摘 要 】

The effects of wind and thermal lift (Stack effect) present particular challenges when measuring the air permeability of large and tall buildings. In high-rise buildings, even small temperature differences between the indoor and outdoor air can lead to undesirably high natural pressure differences on the building envelope. Extreme fluctuations in natural pressure difference can also be caused by wind. This paper presents and compares sets of measurements taken on a 60 m high multi-family Passive House. The building was measured on two separate days in different weather conditions. This paper outlines the extended measurement setup and the measuring process adapted to this setup, as well as the results and findings.
