One of the objectives of the research under the UKERC’s quantitative modelling effort is the review and development of models of energy use by the domestic sector. The aim of this paper is to describe version 3 of the Domestic Energy Sub-model, which models household energy use in the UK as a sub-model within the UK multisectoral dynamic model of the UK energy-environment-economy (E3) system maintained by Cambridge Econometrics MDM-E3. The paper does so by describing the structure of the model and development of different versions of the sub-model, with an outline of the appliances and thermal characteristics of domestic buildings included.
The paper then goes on to explain how households use thermal energy services and describes the characteristics of the buildings and appliances which are included in the model. Finally the paper describes the data collection methodology used to update the model’s dataset from 1995 to 2004 for version 3. Such a description allows the reader to see how the model is structured and how the results of the model are generated, based on the historical data.
