Jalayerian and Jensen Get Technical about Stack Effect in Tall Buildings

New technical guides offered by the Council on Tall Buildings and Urban Habitat (CTBUH) are an eagerly anticipated resource by those in the tall-building industry. The group’s latest offering from two authors from ESD now Stantec has been five years in the making.

In October 2018, ESD now Stantec Senior Principal Medhi Jalayerian led the CTBUH MEP Working Group in developing objectives for what would become the technical guide, “Stack Effect in Tall Buildings.” Over the next five years, Jalayerian and ESD now Stantec High Performance Buildings Studio Leader Tyler Jensen joined forces to bring that outline to life in the recently published book.

The publication explores design considerations for tall buildings in extreme climates that experience Stack Effect, a phenomenon that is primarily driven by the difference between outdoor and indoor air temperature and leads to uncontrolled airflows. This phenomenon can cause potential issues ranging from nuisance airflow and noise to negative impacts on critical life safety systems.

According to the CTBUH overview of the book, “Although basic theories of air flow and pressure in buildings have been well-documented and tested for low-rise buildings, there is no significant technical literature available that documents tall building pressures.” This new technical guide looks to fill that gap.

Mehdi Jalayerian also serves on the Advisory Group for the Council on Tall Buildings and Urban Habitat. He and Tyler Jensen  are co-chairs of the CTBUH MEP Systems Working Group and freely share their knowledge of high-rise and supertall buildings with industry professionals and organizations like CTBUH to promote ESD now Stantec’s mission to foster communities and to improve society through the built environment.

Contact ESD now Stantec’s professionals for more information on how we can help with high performance buildings, building automation, technology, cybersecurity, or other engineering design requirements.
