Building Dynamic Energy Assessment tool (BDEA)
SW#1
REN+HOMES focuses on enhancing software functionalities by providing dynamic energy performance certificates (EPC) assessments and personalised recommendations for achieving energy autonomy and fossil fuel independence using advanced systems. Moreover, a geographic information system (GIS)-based application will be created to assess potential PV or PVT installations in districts and buildings. This tool will seamlessly integrate with the digital building logbook (DBL), ensuring standardised interaction.

State of the art and main challenges
CERTH building dynamic energy assessment tool provides a holistic certification environment that combines current certification approaches while introducing novel indicators under the umbrella of a joined European certification scheme. Additionally, the proposed methodology introduces four sets of indicators to address the building’s performance on the aspects of smart readiness (SRI), environmental assessment (LCA), financial performance (LCC) and human comfort and wellbeing. The tool displays considerable advantages compared to similar SoA applications in the energy assessment domain, such as higher accuracy, accessibility to different scenarios, user-friendliness, and software updates.
Innovations and added value
The purpose in REN+HOMES is to upgrade the software functionalities both to deliver dynamic EPC assessments and to tailor-made recommendations on system dimensions for reaching energy autonomy and independence from fossil fuels. A GIS-based application will be developed and integrated for assessing potential PV or PVT installations in districts and buildings. Users will thus be able to select from a vast array of potential interventions in order to achieve their energy efficiency goals. In addition, the tool will be connected with the digital building logbook, also developed by CERTH, achieving a seamless interaction in standardised manner (BIM models will be used whenever possible).
