Seminar 66 — Stack Effect and Wind Induces Building Pressure Mitigation Strategies in Tall Buildings


Conference Proceeding by ASHRAE, 2021



This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

From previous designs and research, we know that outdoor conditions vary with height. Supertall buildings are taller than 300m and Mega Tall buildings are taller than 600m. At these heights, the outside climate can have both a positive and a negative effect on the space conditions within the building. This seminar will investigate the fluctuation of pressure differentials within the building, especially in relation to stair shafts and elevator shafts, over the height of the building.
