Research summary

Principal Investigator for GEMDev: Grounded Energy Modelling for equitable urban planning development in the global South is an Economic and Social Research Council funded project. GEMDev proposes uses participatory research methods to co-create the data sets with off-grid communities and inform actionable strategies for future redevelopment to ensure dignified housing and habitat for the urban poor. (https://www.ucl.ac.uk/bartlett/development/research-projects/2020/nov/grounded-energy-modelling-equitable-urban-planning-development-global)

Principal Investigator for iNUMBER: (iNtegrated Urban Model for Built Environment Energy Research) is a four-year (2017-2021) research collaboration between India and United Kingdom to help cities reduce their energy demand and improve their electricity and water services. Four academic institutions engaged in India and the UK (CEPT University [Ahmedabad]; Indian Institute of Technology Bombay [Mumbai]; University College London [London], and the University of Oxford [Oxford]), as well as business, and non-profit partners. UK funding from EPRSC through the Newton Fund. (http://www.inumber.org/)

Co-Investigator for CREDS: The Centre for Research into Energy Demand Solutions. Working with researchers, businesses & policy makers, to support the transition to a low-carbon energy system.  CREDS is a major initiative of the Energy Programme of UK Research and Innovation. It is a distributed centre, involving 13 universities, including UCL. It began in April 2018 and will run to March 2023, with a budget of £19.5 million.  Paul is leading the assessment of current energy demand in UK buildings and how this is likely to change over time.

Co-Investigator for Transforming Construction Network Plus: The vision for N+ is to deliver transformational impact by adopting an integrated approach, situating construction as a production system for built assets that adds value to cities and their infrastructures. The network unites academic researchers with industry and policy representatives through networking and skills-building events, creating a new community and body of knowledge to inform future construction policy and practice.  (https://www.ucl.ac.uk/bartlett/construction/about-us/transforming-construction-network-plus)

Teaching summary

Provides lectures to:

  • Sustainable Energy BASC: The Sustainable Energy module discusses the drivers of energy services, the challenges associated with satisfying the rising energy demand, the trade-offs in energy policy aiming to provide secure, affordable, and environmentally benign energy carriers, and the important role of analytical tools for shaping energy policy.
  • Energy Systems and Data Analytics MSc: This programme provides an academically leading and industrially relevant study of energy systems through the lens of data analytics.
  • Health, Wellbeing and Sustainable Buildings MSc, Wellbeing in Buildings: Theory and Practice.

Dissertation Tutor for Smart Energy and the Built Environment MSc: UCL’s Smart Energy in the Built Environment MSc is developed to provide knowledge on the value of smart energy in the built environment and the wider system. It is also designed to provide the skills to take on the challenges we face. The programme brings together both physical and social perspectives of energy demand and supply.  


Paul is Professor of Energy and Building Performance where he leads on research in energyuse and operational performance in non-domestic buildings.  An architect with 40 years’ experience in lowenergy and sustainable buildings he has worked in both academia and industryand always maintained an active involvement in applied research.  His current research focuses on the energyperformance gap in buildings and understanding energy use in buildings at thecity and national scale. 

Paul is the UK alternate delegate and Vice Chair to the IEAEnergy in Buildings and Communities (EBC) Technology Collaboration Programme (https://www.iea-ebc.org/) and he plays aleading role in EBC Annex 70, Building Energy Epidemiology (https://energyepidemiology.org/).

Paul leads the Building Stock Lab at UCL EnergyInstitute, which works on methods for modelling stocks of buildings and theiruse of energy in detail, over large areas (https://www.ucl.ac.uk/bartlett/energy/research/energy-and-buildings/building-stock-laboratory).
