Possibilities of using void to improve natural cross ventilation in high-rise low-cost residential building

This thesis focuses on the study to investiyate the possibilities of improving natural cross ventilation (in term of intemal air velocity, mls) in high-rise low-cost residential building (HRLCRB) in Kuala Lumpur. The HRLCRB design is found complied with the minimum requirement of natural ventilation...
