Prof. Dr. Hazim Awbi is a Professor Emeritus of Building Environmental Science at the University of Reading, UK. He received a BSc and an MSc from the University of Manchester in 1967 and 1969, respectively. Prof. Dr. Hazim Awbi obtained his PhD in industrial aerodynamics at Nottingham Trent University in 1974. His research interests include indoor air quality, indoor thermal environment, building ventilation, computational fluid dynamics application to built environments, heat transfer, energy storage, and renewable energy systems. His research in room air movement has led to the development of novel and energy-efficient room air distribution systems, such as the impinging jet ventilation system and the confluent jet ventilation system.
