The two objectives of natural ventilation in buildings are the improvement of indoor air quality and thermal comfort. The methodology proposed hereafter provides an assessment of the natural ventilation potential for indoor air quality, while taking into consideration the other objective. More precisely, requirements on comfort impose the appropriate ventilation strategies to be applied for eac...

Infectious aerosol dispersion poses significant infection risks (i.e., COVID-19) in classrooms due to dense and long occupancy. Natural ventilation is an effective strategy reduce airborne transmission. The building-related parameters, particularly openings, determine the natural effectiveness reducing contaminant dispersion, necessitating inquiry complex airflow patterns. This paper investigat...

Large modern sports stadia are often multifunctional buildings that are not only used for sports purposes but also for other events such as concerts, conferences and festivities. Some of the stadia that have been built in recent years in north-western Europe are equipped with a semi-transparent roof that can be opened and closed, depending on the weather conditions and on the type of event. Whe...

Passive solar systems such as solar chimneys need solar radiation in order to work. Therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. Phase change materials can save additional thermal energy during the day and release it during the nig...

Abstract Ventilation and air circulation are essential elements in healthcare facilities. Moreover, good ventilation helps to dilute odour pollutants control the spread of disease. This generally uses mechanical ventilation, whereas use natural is encouraged by Indonesian Ministry Health World Organization due its affordability sustainability considerations. Therefore, this paper aims study opt...
