Buildings have been highlighted as one of the primary contributors to environmental difficulties at various phases of construction and operation. Extensive research has been conducted to improve green building designs by employing alternative sustainable construction technologies and operational approaches to reduce energy consumption while optimizing the value of natural resources. One of the methods that have recently become popular in building management is optimizing the potential utilization of natural ventilation inside an interior building space. The purpose of this research is to offer an analytical literature review based on numerous papers and journals to gather and analyze the many sustainable ventilation systems utilized in institutional buildings to promote and improve the quality of airflow within the building. Furthermore, the limits of present studies and future research potential are explored. The findings of this study help to improve the efficacy of sustainable ventilation systems in institutional buildings and give direction for future research on sustainable ventilation in institutional buildings.
