The Building Dynamic Energy Assessment Tool (BDEA), developed by The Centre for Research & Technology Hellas (CERTH) within the REN+HOMES EU-funded project, is a platform aimed at assessing energy performance and smart readiness of buildings by integrating cutting-edge methodologies and European certification schemes. 

The BDEA Tool introduces a holistic certification framework that merges asset and operational rating, aligning with the latest European standards (EN ISO 52000:2017 series). It enhances the evaluation process by incorporating Smart Readiness Indicator (SRI) to assess a building’s capability to integrate smart technologies. In addition, the platform features two unique tools—the renovation roadmapping tool and the SRI Advisor—which guide users in optimising energy efficiency and smart readiness strategies tailored to their specific needs. To ensure seamless documentation and accessibility, all building data is systematically recorded within a digital building logbook. 

'The BDEA platform represents a significant step forward in energy performance assessment and renovation planning. By leveraging advanced digital tools and AI-driven recommendations, we enable stakeholders to make informed decisions that enhance building sustainability and efficiency,' said Stravos Koltsios, Research Associate at CERTH. 

Platform development and key functionalities 

While some components of the BDEA platform were initially developed in previous research projects (D²EPC and SmartLivingEPC), the tool has been overhauled within REN+HOMES to meet evolving industry needs. 

Key functionalities include: 

• Energy Performance Certification: Assesses both theoretical and actual energy performance based on EN ISO 52000:2017 standards, providing an Energy Performance Certificate (EPC).

• Automated data extraction: Integrates Building Information Model (BIM) files (IFC format) and smart meter data for real-time monitoring. • Smart readiness assessment: Evaluates a building’s smart capabilities using the latest European SRI methodology.

• AI-powered SRI advisor: Uses genetic algorithms to recommend optimal upgrades for improving smart readiness.

• Renovation roadmapping: Generates strategic retrofit scenarios based on EPC results, BIM diagnostics, and system analysis.

• Digital building logbook: Provides a centralized repository for building data, including technical drawings, legal documents, and renovation history.
