Integrating statistical data and thermographic survey for assessing energy renovation policies: a review

Despite extensive energy renovation policies implemented across Europe, the tangible improvement in housing energy performance remains slow, particularly evident in Wallonia, Belgium, used as a case study. Identified challenges include mismatches between existing renovation support mechanisms and target demographics, as well as discrepancies between diagnostic tools like the Energy Performance Certificate (EPC) and actual construction realities. This paper is a reminder of two established methodologies to explore their potential synergies in addressing these issues. Leveraging large-scale databases enables the assessment of the building stock's composition and the socio-economic characteristics of residents. Concurrently, thermographic surveys offer rapid identification of atypical cases. Cross-referencing these methodologies reveals their compatibility and complementarity, suggesting a promising avenue for future research to test their combined efficacy in addressing energy renovation challenges.
