Research and expertise

Analysis of monitored building energy demand and empirical modelling of energy demand. 

Summary of expertise 

I have analysed monitored building energy demand to determine savings resulting from various technologies and the factors affecting these savings. I have also analysed heating patterns and the factors affecting these. I have modelling national GB domestic heat demand and heat pump electricity demand based on monitored data from field trials. 

Current research activity 

  • Working as Research Associate on Active Buildings project
  • Working on second paper based on PhD work
  • Contributing to paper on zonal heating controls.
  • Analysing EFUS temperature data.

Recently completed research projects 

  • PhD on empirical modelling of additional electricity demand from domestic heat pumps.

  • MRes Energy Demand Studies



In my PhD I estimated current half-hourly GB domestic heat demand by creating a model based on half-hourly monitored gas demand from a sample of over 5000 homes. I then predicted future GB domestic heat pump electricity demand, based on the model of existing heat demand and monitored data from around 700 homes with heat pumps. 

During the PhD I took a short puase and worked for Loughborough University analysing gas and temperature data from a field trial of zonal heating controls (known as DEFACTO) to investigate the effect of such controls on gas demand and internal temperatures.

In my MRes course on energy demand (at Loughborough University) I developed a model of surface temperatures on artificial sports pitches to predict overheating, and verified this using monitored data. 

Previously I did a Master of Engineering at Durham University, including a final year project on heat recovery from domestic greywater.  The third year of this was studied at Technische Universität Berlin.
