Thermal performance of vertical shafts in buildings: an overview of efficient design parameters

Abstract

There are indications that buildings that include vertical shafts can affect the performance of buildings. Many Publications in major peer-reviewed journals from different fields (energy and buildings) were found using various keywords (Air shaft, light well, vertical shaft, thermal performance, etc.). The review of previous studies was on the role of natural ventilation in vertical shaft buildings in different climates, efficient design parameters, and their application to improve thermal performance and decrease energy consumption. These parameters include various vertical shaft configurations and components such as vertical shaft geometry, opening characteristics, roof properties, and materials. The height, length, and width of vertical shafts significantly impact indoor thermal conditions and energy consumption. The second effective design parameter was the openings, which strongly influence air velocity, air pattern, airflow, air temperature, and ventilation rate.
