Research and expertise

I am building physicist with over 35 years of experience in building energy and environment research and low-energy building consultancy. I have secured 35 research grants, published over 140 refereed publications and supervised 40 PhD students. 

Trained as a civil engineer, I developed an interest in modelling heat and mass transport which led to research work developing and validating dynamic thermal models of buildings. The models were applied to support the architectural design of large, low-energy, naturally ventilated public buildings. 

In recent years I have been particularly interested in understanding and quantifying the energy demand of, and indoor conditions in UK dwellings. This research is pursued through large scale field studies involving monitoring, surveys and questionnaire studies. More detailed investigations are undertaken using our own test houses in which we mimic occupant behaviour, window and door opening, and the use of hot water, appliances and heating. Findings are extrapolated through models, either empirical models or first-principle, building physics models. 

The use of our own primary datasets and others’ secondary data has enabled the development of a method for rating UK homes based on their measured, rather than predicted, energy demand. Patterns of heating within the national housing stock, and the implications of electrification of heat, have been identified. 

Our measurement of indoor temperatures revealed the extent and severity of overheating, which led the UK Committee on Climate Change to press the government to act. Various guidelines and standards, and possible changes to the building regulations, now seek to prevent overheating in new homes.

My career is founded on a degree in Civil Engineering from Nottingham University (1977) and a PhD in geotechnical engineering (1981). After a brief period lecturing at Loughborough University, in 1984 I took a post-doctoral position at De Montfort University (DMU) (then Leicester Polytechnic) to develop methods of validating dynamic thermal models of buildings, a post that set the direction of my future career.  

In 1986 I became a lecture at DMU teaching environmental design in the School of Architecture and progressed to Reader then, in 1996, Professor. Grant funding from the Department of Energy and the BRE supported my research on the development and validation of thermal models of buildings. Through the International Energy Agency, I co-ordinated the world’s largest empirical validation exercise of dynamic thermal models of buildings. Validation of daylighting and CFD models was explored with PhD students, Mardaljevic and Cook respectively, both of whom are now world-leading researchers. Validation is now firmly established in international guidelines and standards.

Between 2000 and 2008 I was the Director of the Institute of Energy and Sustainability at DMU, a financially autonomous centre sustained by research and development work, post-graduate teaching and consultancy. Our expertise in energy, CFD and daylight modelling secured consultancy work from architects and engineers to support the design of 20 large, low-energy, naturally ventilated, public sector buildings. Many of these won engineering and architectural awards. Research on building energy and environment models gradually declined as the models migrated from research centres to mainstream professional practice.

Following a sabbatical at Cambridge University in 2008/09, I moved, with others from DMU, to take up a chair in the, now called, School of Architecture, Building and Civil Engineering at Loughborough University. Research concerns about the sustainability of urban areas and the needs to understanding the actual energy demands of buildings took centre stage; a research thread made possible by the advent of small, low-cost sensors and the internet of things. Large-scale field trials, in hospitals and homes, has provided a picture of the factors influencing energy demand, and the success, or otherwise, of refurbishment strategies and heating controls for reducing this demand. Unexpectedly, the work also revealed the serious problem of overheating in UK homes.

Since 2009, I have been the Director of the London-Loughborough Centre for Doctoral Training (CDT) in Energy Demand and more recently the CDT in Energy Resilience and the Built Environment. The Centres will train over 150 PhD students who will be the future leaders in the struggle to create a safe, secure, clean and socially equitable energy system for the built environment.
