Grzegorz Sztarbała is a graduate of the Faculty of Environmental Engineering at Warsaw University of Technology, with specialization in Heating and Ventilation. Since 2001 he has been working at the Fire Research Department of Building Research Institute. In 2012 he was awarded with the title of doctor of technical sciences in the field of construction for the doctoral thesis “The impact of wind on the airflow in the tunnel in case of fire.” Since 2006 he’s been a lecturer at the graduate studies at Warsaw University of Technology – “smoke extraction systems – smoke control ventilation”. He was also a lecturer at the Faculty of Civil Engineering, Architecture and Environmental Engineering of Lodz University of Technology. Starting in 2013, he is an employee of the ARDOR company, where he develops the concepts of smoke control ventilation systems, numerical calculations of smoke and heat control, simulations of evacuation process and assessment of the effectiveness of smoke control ventilation systems. Since 2013 he’s chaired the working group of the European Committee for Standardization CEN TC191 / SC1 / WG5 “Design and calculation methods for smoke and heat exhaust ventilation systems”. In addition, he is an expert of the Polish Committee for Standardization in the European Committee for Standardization within the committee: CEN TC191/SC1/WG2 – Natural smoke and heat exhaust ventilators and CEN TC191/SC1/WG9 – Smoke control in covered vehicle parks, where he chairs the task force within the European CEN TC191/SC1/WG9/TG1 – Computational Fluid Dynamics (CFD).
