  • Chiller optimization through data analysis
  • Life cycle assessment of building system

Ir Dr Alan Fong obtained his bachelor (1996) & master degree (2004) in Hong Kong Polytechnic University and his PhD (2015) in De Montfort University, Leicester, UK. Before he has joined City University of Hong Kong in August 2007, he has over fifteen years practical experiences in the building services consultancy and contracting industry. He is expert in system design and project management of building services systems installation involving institutional, infrastructural projects, hotel, industrial, offices, commercial and residential development in Hong Kong, Macau and Mainland China.


His mission is to broaden student’s interest and horizon on aspect of building services engineering by means of his academic knowledge, intensive design practical experience, management and real-life industrial worldwide practices related to building development services engineering.


He started research work concerning thermal comfort survey and field measurement work related to energy saving aspects since 2009 supported by Divisional Research Grant (DRG). He has involved in different consultancy work in resolving various building services engineering problems.
