In the SmartLivingEPC project, digitized tools play a crucial role in using data and insights to optimize building performance. Through BIM literacy, advanced technologies are leveraged to retrieve comprehensive assessment information, providing valuable insights into building operational behaviour across its life cycle. Aspects of smartness and technical system performance are delved into, extending to cover critical areas such as water consumption, noise pollution, and acoustics. The seamless alignment with digital logbooks and building renovation passports is ensured, guaranteeing compatibility and ease of integration. The certification system operates on two levels: at the building level, marked by Building EPC certification, and at the building complex level, extending to the neighbourhood scale. As the first reporting period concluded, the outcomes of the project made significant strides towards sustainable and efficient building practices.

The SmartLivingEPC project is currently in its 22nd month of operation. Significant steps have been made within the SmartLivingEPC project towards advancing energy performance certification across the European Union. EPC rating schemes have been identified in 10 EU countries, shedding light on their methodologies and barriers. Stakeholder requirements and market needs have been thoroughly extracted, with emphasis placed on the importance of EPC compliance, standardized labels, transparency, and financial support for energy efficiency initiatives. Architectural, functional, and technical specifications for the SmartLivingEPC framework have been defined, encompassing three Business Groups, 10 Business Scenarios, and 25 Technical Use Cases, each meticulously detailed. Additionally, 47 functional and 14 non-functional requirements crucial for the framework's success have been identified.

A methodology for calculating asset ratings has been developed, unifying all key performance indicators within a single framework. A comprehensive exploration and definition of indicators for assessing building operational performance have been also undertaken, leading to the development of an initial operational rating calculation methodology. Additionally, the Common Information Exchange Model (CIEM) for Smart Living EPCs has been established and significant progress has been made in building dynamic behaviour monitoring that provides occupancy estimation, profiling, and energy consumption forecasting models based on IoT data. Furthermore, a Smart Living Building Digital Twin architecture and digital logbooks (DBL) for EPCs have been created. In parallel, development efforts are ongoing for EPC calculations and APIs for third-party applications, alongside with the definition of the functionality of Added Value AI tools and Benchmarking and evaluation tool. Efforts also extend to the development of a SmartLivingEPC Web Platform, training and guidance methodology, and data collection from pilots. Prioritization of communication and dissemination is evident through an operational website, social media presence, newsletters, and promotional materials. Additionally, active contributions are made to standardization initiatives, and collaboration with sister projects shapes policy recommendations for the Energy Performance of Building Directive Recast.
