Professor of Energy and Environment
University College London


Professor Tadj Oreszczyn is the Director of The Bartlett School of Environment, Energy and Resources (BSEER), Director of the RCUK Centre for Energy Epidemiology (CEE) and Professor of Energy and Environment at the UCL Energy Institute, University College London. Prior to becoming the Director of BSEER in August 2014, Professor Oreszczyn was the founding Director of the UCL Energy Institute, a highly multi-disciplinary group of 170 staff and MSc/MRes/PhD students working on a £28m portfolio of funded projects.

The UCL Energy Institute has the aim of accelerating the transition to a globally sustainable energy system through world-class energy research, education and policy support. Professor Oreszczyn is also the Director of the RCUK Centre for Energy Epidemiology based at the UCL Energy Institute. This centre undertakes research to help the UK reduce its energy demand in buildings and transport and is one of six government funded research centres in energy demand. The centre is currently leading the establishment of an International Energy Agency Annex (70) in building energy epidemiology.

Professor Oreszczyn has for 34 years undertaken energy and building research with a particular focus around the performance gap between theory and practice and the unintended consequences (health, comfort, etc.) of building energy efficiency. He has been involved in over 170 research publications. He was invited to give evidence to the House of Lords Science and Technology Select Committee on Energy Efficiency, and he has co-authored two papers for the special issues of the Lancet on Energy and Health and prepared three papers for a State of Science Review for the Office of Science and Innovation. Professor Oreszczyn has provided research support for the development of the English and Welsh Building Regulations and he has presented at invited public and academic lectures at the Royal Society and the Royal Institution. Professor Oreszczyn is a Fellow and a Vice President of the Chartered Institution of Building Services Engineers (CIBSE) and sits on the CIBSE Board.


Household energy efficiency and health: Narrowing the performance gap with the help of energy epidemiology

Energy efficiency programmes and policies in the UK have reduced residential energy demand and improved health and comfort. However, uptake and efficacies of energy efficiency programmes must be radically improved if UK carbon emission targets are to be achieved. What lessons have we learnt over the last 40 years, and what are the essential tools and policies required to deliver a healthy and energy efficient building stock? Can research methods from other sectors such as health epidemiology and data science better help building scientists understand this complex socio-technical problem? The presentation will draw on examples of research from the RCUK Centre for Energy Epidemiology, analysing, energy, building and people data from millions of homes, and modelling energy use in the English housing stock. Current research bringing together health and energy data and the new “IEA Annex 70 – Building Energy Epidemiology: Analysis of real building energy use at scale”, will be described.
