This report provides a summary of the research activities in the research project RP3028: A Virtual Market for Analysing the Uptake of Energy Efficiency Measures in Residential and Commercial Sectors.

To enable the development of policy programs to increase adoption of energy-efficient products, there is a need to develop a knowledge base from which it is possible to understand the likely success of policy interventions.

The required knowledge will be based on a combination of data and observations from which to develop either a mental or a computational model. These models, in turn, will guide the policy design, implementation and evaluation process.

The effort to increase energy efficiency in the residential sector, depends to a large extent on the consumer behaviour of residents, and in this report, we provide a summary of the complexities of consumer choice. These aspects of consumer choice have been embedded into an Agent-Based Model of household energy efficiency adoption, and this model is described in this report.
