Research summary

Cliff’s research interests build on his experience in physical sciences, physics and materials science, and in data analysis. He has an active interest in applying the tools and techniques – measurement, experimental design, statistical methods etc – of these disciplines in the energy demand domain.

Cliff’s core interest is in the measurement of energy use, and parameters related to it, to characterise the performance of buildings, building elements and systems. He works with the Physical Characterisation of Buildings team to undertake monitoring campaigns, develop physically informed models, undertake analysis and relate the outcomes to the complex socio-technical factors that affect building performance, and policies and practices that may support reductions in carbon emissions.

 Recently Cliff has contributed to a range of projects, including:

- The development of a novel technique to characterise the thermal performance of building elements utilising Bayesian analysis

- Investigation into the distribution of airtightness test results for new UK dwellings, and how they relate to targets set for compliance purposes.

- Investigation of the thermal performance of floors and walls, and the unintended consequences of retrofitting

- Estimation of the efficiency improvement associated with the replacement of conventional with condensing boilers in the building stock from national datasets

Cliff was previously seconded to the Energy Technologies Institute (ETI), where he developed a holistic vision of smart energy systems.

Teaching summary

Cliff is Deputy Director of the EPSRC Centre for Doctoral Training in Energy Demand (LoLo) and the CDT in Energy Resilience and the Built Environment (ERBE). His role centres on delivery of the core goals of the CDT, primarily to promote and develop excellence in the provision of doctoral training, to undertake world class research on energy demand and the built environment and to deliver first class researchers into the workforce. More information on the centre is available on the LoLo webpage (http://www.lolo.ac.uk/).

Cliff teaches on the MRes Energy Demand Studies programme, leading the Guided Research Project - a mini-research project where students undertake original research on a supplied dataset. The data analysis and tutorials are complemented by lectures on key topics such as an introduction to data analysis, and some topics in statistics. Cliff also teaches academic writing as part of the Communication Skills module.

Cliff supervises PhD and masters students on a range of topics related to his research interests.

Cliff has previously been Course Director of the MRes EDS and Departmental Graduate Tutor (Research) for the Bartlett School of Environment, Energy and Resources (BSEER), overseeing and providing support to the School's MPhil, PhD and EngD students and their supervisors.

Cliff Elwell is an Associate Professor at UCL Energy Institute, where he leads the Physical Characterisation of Buildings group, co-leads the UCL-Energy Buildings Theme, and is Deputy Director of the EPSRC Centre for Doctoral Training in Energy Demand (LoLo) and the forthcoming CDT in Energy Resilience and the Built Environment (ERBE).

 Cliff’s research interests are primarily in building physics, focussing on characterising the performance of buildings, building systems and building elements through in situ monitoring and analysis using a range of methods. His work often features the application of physically informed models and Bayesian analysis.
