The UCL Energy Institute delivers world-leading learning, research and policy support on the challenges of climate change and energy security. Our approach blends expertise from across UCL, to make a truly interdisciplinary contribution to the development of a globally sustainable energy system. We are part of The Bartlett: UCL's global faculty of the built environment.



Tadj Oreszczyn FCIBSE MInstE, PhD, CEng is the Director of The Bartlett School of Environment, Energy and Resources (BSEER) and Professor of Energy and Environment at the UCL Energy Institute. Prior to becoming the Director of BSEER in August 2014, Tadj was the founding Director of the UCL Energy Institute.  Tadj is also the Director of the RCUK Centre for Energy Epidemiology (CEE) based at the UCL Energy Institute.  This centre undertakes research to help the UK reduce it's 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.

Before becoming Professor, Tadj was the Director of the Energy Design Advice Scheme (EDAS) regional office based at the Bartlett, UCL. Subsequently, Tadj was Head of the Bartlett School of Graduate Studies for 7 years, and for 4 years, Vice Dean Research for the Bartlett Faculty of the Built Environment. Tadj has provided research support for the development of the English and Welsh Building Regulations.

Tadj is a Fellow and a Vice President of the Chartered Institute of Building Services Engineers (CIBSE) and sits on the CIBSE Board. Tadj is a member of the Advisory Board of the National Energy Foundation, a member of the NHBC Expert Panel, and a member of EDGE an inter-institutional ginger group involving CIBSE, ICE, RIBA, IStructE and the RICS which seeks to promote interdisciplinary co-operation between construction professionals. Previously Tadj was a member of the UK Department of Energy and Climate Change (DECC, now BEIS) Scientific Advisory Group and has advised the Energy Efficiency Deployment Office at DECC.

Research Summary

Tadj 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. His first degree was in Applied Physics followed by a PhD in Solar Energy.

Tadj 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, co-author two papers for the special issues of the Lancet on Energy and Health and prepare three papers for a State of Science Review for the Office of Science and Innovation. Tadj has provided research support for the development of the English and Welsh Building Regulations. He has presented at invited public and academic lectures at the Royal Society and the Royal Institution.
