The SmartLivingEPC project delivered a next-generation EPC rating framework that extended beyond existing standards by integrating asset and operational performance at both building and complex levels. The asset performance evaluation combined energy efficiency, sustainability, life cycle, non-energy aspects and technical inspections, incorporating indicators such as the Smart Readiness Indicator (SRI), Level(s), and technical inspection outcomes into a single, unified building classification. The operational performance evaluation incorporated Indoor Environmental Quality (IEQ), energy efficiency, and Life Cycle Cost (LCC) indicators, providing a comprehensive assessment of occupant health, comfort, productivity, and financial performance. The framework offers a more holistic and actionable perspective than traditional EPCs.
SmartLivingEPC was fully BIM and Digital Twin-compatible, enabling near real-time integration of building data with physics-based models. The Smart Living Building Digital Twin provided continuous, real-time monitoring at both individual building and complex levels, supporting predictive insights and scenario simulations. The project introduced advanced tools that went beyond standard EPC functionalities, including the Digital Building Logbook, Nudge-ready Performance Benchmarking & Evaluation, and Dynamic Behaviour Monitoring System, enriched with AI capabilities for anomaly detection and performance optimization. All results were visualized through a unified Web and IoT platform, providing actionable insights to stakeholders, supporting decision-making, and enabling proactive building management. SmartLivingEPC thus represented a holistic, intelligent, and future-ready EPC system, surpassing the state-of-the-art in energy performance, sustainability, smart readiness, and operational intelligence.
To ensure further uptake and maximize impact, additional demonstration and validation in diverse building types and climates are recommended. Support for commercialization and market deployment of the digital platforms and tools, together with protection and management of intellectual property, will facilitate adoption. Efforts to extend the methodology internationally, as well as continued alignment with regulatory frameworks and standardization initiatives, are essential to ensure interoperability and broad recognition. Access to financing and incentive schemes will further support uptake by building owners, policymakers, and other stakeholders, consolidating SmartLivingEPC as a reference framework for future EU energy and building policies.
