Description:	This research was conducted to investigate the potential of void to enhance natural ventilation performance in the living units of multi-storey housing. This research focuses on Malaysian affordable multi-storey housing (MAMSH). Most multi-storey housings do not really provide a good control of natural ventilation performance to achieve a healthy and comfortable living environment. This is caused by poor building design. The size of void in MAMSH current design complies with the minimum requirement as stated in the Uniform Building By-Laws 1984[G. N. 5178/85]. Though it complies, this research was conducted in studying its contribution to the natural ventilation performance. The methods employed by the research are field measurement and computer simulation using CFD software, ANSYS CFX v14.5. The measured building was selected based on the inventory analysis of MAMSH typologies. The measured data was then used to validate the CFD simulation. A pilot study was executed to determine the effect of voids on natural ventilation performance by comparing CFD simulation and wind tunnel data from the previous study. There are three stages in CFD modelling; firstly, validation model for setting up the environment similar to field measurement, secondly, based model that simplifies the measured building due to convergence factor, and finally, the suggested model in which the existing size of MAMSH is adjusted for different sizes of voids, different sizes of openings, and different conditions of openings. This study reveals that the air velocity (m/s) and ventilation rate (m3/s) in the living units for the existing size of void do not achieve the required rate for thermal comfort and health purpose. However, by the changing size of void by 50% to 75% of the living units, the air velocity (m/s) and ventilation rate (m3/s) in the living units is increased by up to 50.48% and 18.8% respectively. The appropriate size of void are recommended is based on the results and findings. This research contributes to the development of knowledge in enhancing natural ventilation performance in buildings. The suggestions might help the building industries to provide better designs option to enhance natural ventilation performance in the living units of multi-storey housing by providing appropriate size of void, and in turn, a sustainable living environment can be established.,Certification of Master's/Doctoral Thesis" is not available
