Biography:Dr. Laloui Hamza is an active researcher in passive cooling design in residential buildings, specializing in the design of the natural ventilation passive design features, energy efficiency, indoor air quality, thermal comfort evaluation of the naturally ventilation environment, natural ventilation modelling and ventilation impacts on people health and wellbeing, high rise residential building and numerical methods (computational fluid dynamic “CFD”. Dr. Laloui Hamza, Ph.D. thesis from International Islamic University “IIUM”, Malaysia established the research mainly to the field of natural ventilation research. The research aimed to provide passive integrated design features for the problem of naturally ventilation single sided ventilation mode in the layout of high-rise residential buildings in tropical climates.

Abstract: The research aims to investigate and evaluate the impacts of the voids combination as a passive design feature on wind-driven ventilation performance in high-rise residential building units. It proposes a series of building models and thereon indoor ventilation performance and outlining why and how these building models designed with architectural design features are important. The study aims to provide a comprehensive understanding of how natural ventilation as a passive cooling strategy in living units of high-rise residential buildings can be applied through improving the provision of the architectural design feature of voids configurations. The study was carried out through field measurements experiment and the computational fluid dynamics methods (CFD). A series of numerical simulations were carried out to calculate the indoor ventilation rate and velocity inside the case studies of the generated building models based on various variables such as horizontal voids type, size and wind directions. The results indicate that the provision of a single-sided horizontal voids in building models can improve the indoor ventilation in units with cross ventilation mode up to 4 times, depending on wind direction and living unit location. The indoor ventilation performance in units located in models with single sided horizontal voids is 17.54% higher than the units located in models without voids configuration. Furthermore, higher indoor ventilation performance was achieved in the case scenarios located at higher levels compared to the middle and lower levels in both horizontal void types. This study explores the application of voids combinations for natural ventilation performance, investigates the numerical simulation results and validates field measurements experiment data using CFD simulation.
