Abstract AR

Improving the performance of natural ventilation in multi-storey buildings is important for living in terms of health and thermal comfort.

One of the most important design strategies to improve natural ventilation in multi-storey buildings is by exploiting the voids inside the building.

What is meant by voids here is the negative part of the built-up block such as skylights, courts or stairwells, which are usually located in the middle of the multi-storey residential building.

Therefore taking care of designing voids in buildings from the beginning is crucial in order to obtain good natural ventilation.

The experiment was conducted in this research on a four-storey hypothetically existing building.

This study aims to explore the effects of voids inside the building on the efficiency of natural ventilation by incorporating two of voids forms avoiding any change in windows size or place.

To assess the situation and reach the results, the experimental method was adopted and computational fluid dynamics CFD model was used.

The major determinant used for assessment is the volumetric flow rate which is necessary for thermal comfort and health.

This study revealed quantitatively what is known theoretically that including voids within the ventilation system and increasing their area can greatly enhance the efficiency of natural ventilation in the multi-storey building.
