Dr David Glew


Dr Glew is Head of Energy Efficiency at the LSI and manages the LSI interdisciplinary research projects on domestic retrofits. Over the last 5 years he has been responsible for delivering research contracts worth over £3 million, aimed at informing energy policy. He has published in multiple peer review publications, supervises doctoral students in the LSI and has been appointed to government advisory panels.

Dr Glew is experienced in managing large and complex interdisciplinary projects that address energy demand through a variety of Building Performance Evaluation (BPE) tools, including field tests, in use monitoring and smart meter data, as well as investigate behaviour change, the use large data sets, and how hygrothermal and energy modelling can be used in predictions of future scenarios. In his research he is exploring the accuracy of novel BPE tools including the PUSLE and QUB tests and the use of smart meter data to inform policy. His work has critiqued the design of energy policy, as well as identified pathways to minimising perforce gaps and unintended consequences and improve occupant health and wellbeing. David is also interested in Greenhouse Gas emissions and performing Life Cycle Assessments on products and processes.

Dr Glew is involved in policy development in the area of domestic energy efficiency; he has been appointed to Ofgem Technical Advisory Panels to assess new innovations, contributed to Government calls for evidence, Select Committee inquiries, All Party Parliamentary Groups and being a member of work streams for the Each Home Counts industry review of retrofits which has resulted in a new Quality Mark and PAS2035. He has also spent time seconded to BEIS where he worked on evaluating and designing research projects to inform policy teams and ministers. David has managed a series of other research projects and Knowledge Transfer Partnerships (KTP) with public bodies and industry ranging from investigating the thermal performance of local housing associations’ housing stock before and after an eco-renovation, to analysing and comparing energy efficiency between different supermarket stores.

Current Teaching

Dr Glew leads the LSI doctoral programme and has supervised 15 doctoral research students over the last 5 years, including 4 as Director of Studies.

Some of his students' topics have included:

  • The QUB method for assessing the energy efficiency of buildings
  • Increasing the supply of new low energy homes for the UK
  • Thermal Comfort Perception in Multi-Purpose Sports Facilities
  • Evaluating the testing of existing properties for informing choices of effect thermal upgrade with specific reference to traditional 225mm solid walled buildings
  • Understanding the Barriers to the Uptake of Energy Data Analytics in Large UK Manufacturers. Solar Power forecasting and Design of Micro grid
  • Solar Power forecasting and Design of Micro grid
  • Analysis of Display Energy Certificate and Advisory Report Non-Compliance, Non-Lodgement and Poor Rating Despite recommendations
  • The development of a post-occupancy evaluation method considering the complexity of the building’s life-cycle
  • Unintended Consequences: To what extent to discontinuities of internal wall insulation retrofitted to solid masonry walls increase the risk of condensation formation and mould?
  • Addressing the hidden performance gap in thermal retrofits: Installers as the gate way to driving up standards

Research Interests

Research insights from Dr Glew's work include:

  • Insulating floors, rooms in roofs and improving air tightness in homes can each reduce heating demand by as much as solid wall insulation
  • Novel thin insulation materials have lower moisture risk than conventional insulation products while still providing 80% of the energy savings for only 2/3rds the cost and also with lower risk of condensation
  • Dissemination of ECO policy requirements are inappropriate, resulting sub-standard retrofits being delivered to 200,000 to 500,000 homes under ECO policy
  • Energy price caps use flawed off peak demand estimates, causing higher bills for millions of vulnerable households
  • ECO policy funding structure ignores the whole house approach meaning over 85% of homes receive only 1 intervention per retrofit
  • EPCs, used for policy evaluation, contain errors meaning 19% of homes may be in the wrong A-G band
  • End of life is often excluded from energy analyses, undervaluing the benefits of biomaterial products
  • Low energy housing policy could increase overheating and discomfort if occupant behaviour is ignored
