Design and implementation of a novel open-source web-GIS application for a harmonized EPC documentation across Europe

Abstract

In recent years, there has been a growing demand for buildings that are energy efficient. As a result, there is a need for a standardized and advanced framework for issuing Energy Performance Certificates (EPCs). Various organizations, including the European Commission, have emphasized the importance of improving EPC schemes and propose the adoption of a common, homogenous scale of energy classes ranging from A to G. This framework will ensure a more accurate evaluation of the actual energy performance of buildings. Moreover, technological advancements and innovative digital Geographic Information System (GIS) and webGIS tools have enabled the capability to handle and visualize a huge amount of energy performance data. This, in turn, provides a more comprehensive and accessible representation of energy consumption and efficiency at various scales, including dwellings, buildings, regions, and countries. The EU-funded research project entitled "Next-generation Dynamic Digital EPCs for Enhanced Quality and User Awareness" (D^2EPC GA 892984) introduces a comprehensive approach to next-generation Energy Performance Certificates. This approach addresses the main challenges and gaps in the buildings' energy assessment process, based on a common methodology for buildings across the European Union. The webGIS tool, as a part of the overall solution, offers advanced analytical tools, querying, and visualization functionalities, which include mapping and comparison of Energy Performance Certificates (EPCs) statistics across various geographical scales, attribute and geographical querying, and 3D visualization through the integration of Building Information Models. Our tool also facilitates data interoperability, ensuring seamless data exchange and analysis.
