Title: Stack effect in high-rise buildings – importance of the curtain walling, windows and doorsets airtightness for the building performance
Keywords: Stack effect, high-rise buildings

Abstract: This paper presents a review of the stack effect phenomenon in high-rise buildings and the associated implications related to the façade curtain walling, windows and doorsets airtightness quality. A 150 m tall office building was numerically modelled with two different classification grades of the construction elements as specified in the European Standards EN 12152 and EN 12207. The analysis was performed under both winter and summer weather conditions (0.4 % of the time exceeded), specified in ASHRAE Handbook - Fundamentals. The numerical results have demonstrated the importance of the construction elements’ airtightness properties to the overall building performance. For both winter and summer conditions, the infiltrations in the building have been reduced with 21% by improving the façade airtightness quality from Grade 1 to Grade 2. At the same time, it was observed an up to 35% decrease of the differential pressures at the interior doors.
