Periodic Reporting for period 2 - PRECEPT (A novel decentralized edge-enabled PREsCriptivE and ProacTive framework for increased energy efficiency and well-being in residential buildings)
Berichtszeitraum: 2021-10-01 bis 2023-03-31
PRECEPT strives to achieve its ambitious objective by introducing a Pred(scr)ictive and Proactive building energy management system (PP-BMS) installed locally at the building level, able to rapidly and efficiently self-manage, self-monitor, self-heal and self-optimize itself, with minimal human intervention, whenever there are system malfunctions, significant deviations in the forecasted weather conditions affecting both thermal and visual comfort as well as RES generation, occupancy schedules, flexibility forecasts, energy tariffs, loads-scheduling, and level of utilization. PRECEPT aims to provide novel techniques for supporting the collection, analysis and visualization of the expected large volume of data. Furthermore, PRECEPT will deliver and integrate building digital twins that will be continuously updated with real-life data for early prediction, automatic repair, and optimal building operation. PRECEPT also realizes the importance of user communication and user communities. To this end, PRECEPT plans to develop a social collaboration platform where users may exchange information, experiences, and best practices. PRECEPT will also introduce standardized procedures for data management and building proactiveness that will contribute to the development of the required Smart Proactiveness Indicators (SPIs) of the building. PRECEPT also aims to deliver AI algorithms dedicated to prescriptive maintenance exploiting historical building information, as well as local climatic data, and creating appliance/device behavioural models. Lastly, PRECEPT will introduce, implement, and demonstrate novel sustainable business models for transforming traditional reactive buildings into proactive buildings.
Furthermore, the PRECEPT ecosystem and its infrastructure were successfully deployed in all pilot sites after continuous communication with the pilot tenants. The innovative PRECEPT Pred(scr)ictive and Proactive building energy management system (PP-BMS) was developed and its integration with the digital twin platform and other system components was defined. Its user recommendation system has also been built by exploiting a state-of-the-art overview of all controllable loads. Novel methodologies utilizing machine-learning techniques were explored to achieve accurate and reliable disaggregation of energy consumption at the appliance level. Monitoring data from real-life test cases in combination with other data sources such as weather APIs were leveraged and provided valuable insights into occupants’ behavioural, energy consumption and comfort patterns while state-of-the-art research was examined to predict human behaviour accurately. Disaggregation, human comfort, activity and occupancy models as well as the PRECEPT Proactive Building Operation module and the PRECEPT Proactive RES & Storage management modules were developed and validated. Additionally, innovative advancements in anomaly detection, human behaviour and comfort were made and integrated into the PRECEPT inference engine. At the same time, PRECEPT has cultivated a robust online presence and participated actively in physical events like conferences, trade fairs and workshops and continuously explores novel business models for the exploitation of the project’s results.
