Doctor Vahid Vakiloroaya

Contact Details


Dr Vahid Vakiloroaya joined the Centre for Infrastructure Engineering (formerly the Institute for Infrastructure Engineering) in 2015 as a postdoctoral research fellow. Holding Bachelor's and Master's degrees in Mechanical Engineering, Dr Vakiloroaya completed his PhD in Mechanical Engineering at the school of Electrical, Mechanical and Mechatronic Systems (EMMS), UTS, Australia in 2015 where he was selected as UTS green hero for his PhD project. He also served as a committee member of the faculty and academic board at UTS during his time there.

Prior to academic research, Vahid has fourteen years of working experience as a design engineer in HVAC and energy for sustainable development and was awarded with a 2005 Hitachi Best Practical Engineer Award.  He is the author of eleven engineering books and one book chapter about heating, ventilation and air conditioning (HVAC) system design, calculation and implementation. He is also the author of many research papers in international conferences and journals, with two international patents pending. 

He has won several prestigious awards for his work on HVAC and building energy efficiency including Excellence in HVAC and Refrigeration Research Award 2013 by Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH), NASSCOM Australia Innovation Award 2013, Consensus Innovation Award 2014 and Sir George Julius Medal by Engineers Australia 2015.
