This presentation will discuss stack effect impacts in tall buildings. Stack effect respresents an uncontrolled energy loss and can cause irritating noise, infiltration of humidity or odor, drafts and thermal discomfort, etc. This presentation will increase the awareness of how to control and manage stack effect through passive strategies.

Learning Objectives:

  1. Be able to describe the physics that causes stack effect and what it means for the design of sustainable buildings.
  2. Understand how to control the location of the neutral plane, and why this is important for stack effect as well as natural ventilation.

  3. Understand the role of the ventilation system in managing stack effect impacts and how this affect the overall buildings energy reduction goals.

  4. Realize through case studies how to control stack effect and how important this can be, especially how it affects sustainable building goals and energy reduction
