The European Green Deal aims to make Europe climate neutral by 2050, with a 55% reduction in
greenhouse gas emissions by 2030. Improving energy efficiency in buildings is crucial to achieving this
goal, and Energy Performance Certificates (EPCs) play a key role in this process.
Despite their importance, current EPCs have limitations and deficiencies, including a lack of reliability.
The EPC RECAST project seeks to improve EPCs by addressing these issues. Particularly, the work
presented in current report, corresponding to Task 1.4, aims to enhance EPC reliability by exploiting
measured energy data and energy performance modelling. The ultimate goal is to provide tools to
support EPC assessors in mitigating the gap between predicted and measured energy performance,
thereby improving EPC reliability.
Present document is divided into six chapters to describe the outputs of Task 1.4, including a first
chapter to framing the work, a second chapter dedicated to review current approaches to energy
performance assessments, a third chapter covering an analysis of potential sources of energy-related
measured data, two chapters to describe proposed protocols to improve energy performance
assessment reliability, specially, Chapter 4 that sets out a methodology for calibrating energy models
and Chapter 5 that depicts an improved methodology for assessing operational energy performance.
Finally, the conclusions are gathered in Chapter 6.
