Analysis of monitored building energy demand and empirical modelling of energy demand.
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. I have developed a new approach to modelling domestic energy demand based on monitored data.

Before becoming a lecturer, I worked for two and a half years as a Research Associate in the Building Energy Research Group at Loughborough. During this time I developed a new approach to modelling domestic energy demand based on monitored data, applicable to individual dwellings and groups of dwellings.
This work was carried out through the Active Building Centre. I also analysed ERUS internal temperature data to assess overheating and the existence of “safe havens”, assessed energy savings from zonal heating controls based on DEFACTO field trial data, and developed models of compact hybrid heat pumps based on monitored boiler data.
In my PhD I estimated the 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 pause 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.
