The DEFACTO Field Trial: Methodology and Data Sets

The DEFACTO Field Trial was undertaken as part of a 6-year EPSRC-funded research project (grant EP/K00249X/1) from 1 November 2012 to 31 October 2018, aimed at measuring the energy saving capability of so-called ‘smart’ heating controls when used with gas-fired, low-pressure hot water central heating systems. This report describes the conduct of the field trial, the methodology adopted for its execution, the data that were collected and the cleaning of those data. Materials used in the field trial are presented in Appendix A (Pilot Study) and Appendix B (Main Study) to this report.
