InDEED Investigating Domestic Energy Efficiency Data analytics
Identifying errors in EPCs
Funded was provided by the Economic and Social Research Council via the Consumer Data Research Centre. Energy Performance Certificates (EPCs) give people an idea of how energy efficiency their homes are, but EPCs are notoriously unreliable and full of errors. This project identifies EPCs which are likely incorrect allowing them to be removed from any analysis. The project found that a large number (up to 62%) of EPCs contain at least one major error, calling into question how useful they are as a measure of energy efficiency in their current form. Furthermore, the errors found in each region of the UK varies considerably, with London containing the most.
