Research summary

Dr Argyris Oraiopoulos is an expert in Urban Building Energy Modelling. His research focusses on reducing energy demand in buildings for achieving national decarbonisation targets, while ensuring healthy indoor environments. The aim of his work is to use urban building energy modelling tools for exploring the impact of decision-making parameters on the current and future energy demand across building stocks, as well as the consequences of demand reduction strategies on health and wellbeing, especially of vulnerable population groups.

Dr Argyris Oraiopoulos is currently a Research Fellow in Urban Building Energy Modelling and Thermal Comfort at UCL Energy Institute. Argyris holds a bachelor’s degree in Civil Engineering, a master’s degree in Water and Environmental Engineering, both awarded by the University of Surrey, and a master’s degree in Environmental Design and Engineering awarded by UCL. He completed his PhD at Loughborough University where he developed stochastic and descriptive time series models for the prediction of summertime overheating in UK homes. Argyris has previously worked at the Science and Innovation for Climate and Energy (SICE) directorate in the UK’s Department of Business Energy and Industrial Strategy (BEIS) and also has 5 years of experience in post-doctoral research positions, in the UK (UCL - Energy Institute, Loughborough University - School of Architecture Building and Civil Engineering) and Switzerland (ETH - Institute of Technology in Architecture). 

In the past Argyris has acted as Scientific Co-Chair at the prestigious European Council’s for an Energy Efficient Economy (ECEEE) conference as well as at the highly regarded International Building Performance Simulation Association’s conference (England), where he also sit as a member in its global conference committee. Argyris is a qualified Mental Health First Aider and a STEM Ambassador, delivering workshops in primary and secondary schools across the UK, raising aspirations and encouraging students to progress to Higher Education.
