This report summarises EPC methodologies currently in use across chosen European countries, focussing on those relevant to the crossCert project. The information collated will act as a reference document to highlight differences in approaches to energy assessment and, by extension, different responses to the Energy Performance in Buildings Directive.
By conducting this review, EPC approaches are categorised based on type of calculation methodology used, methods of input data gathering, use of real building and/or energy data, and outputs generated from the EPC process. This categorisation will aid later analysis in the project, where crossCert will investigate the impact that country-specific EPC choices have on EPC outputs, as well as any consequences of these outputs.
The goal is to address the technical dimensions of EPCs (including inputs, metrics, and control/verification) in order to identify potential improvements and guidelines. The work is also the basis for harmonisation recommendations to be compiled at a later stage. The first step is studying different EPC methodologies used in crossCert project partner countries. This deliverable is focused on reviewing general aspects as well as some technical details of EPC assessment methodologies.
