Energy monitoring in heating and plumbing systems to improve energy efficiency
To date, building services systems, buildings and users have each achieved significant success in energy saving in their own right. Further potential lies largely in the interaction between these components. The available data is generally insufficient to identify and quantify efficiency potential during ongoing operation – particularly in heating and plumbing systems – whilst taking user behaviour into account. As part of the Energy Monitoring project, the heating technology and drinking water hygiene laboratories are being expanded.
Project duration: October 2024 – September 2026

SUSIC
Smart Utilities and Sustainable Infrastructure Transformation
Climate change, the energy transition and urbanisation – a sustainable, efficient and, at the same time, cost-effective energy supply is increasingly becoming the focus of public attention. As part of the Smart Infrastructure Hub Leipzig, the University of Leipzig and HTWK Leipzig are therefore conducting research within the framework of the collaborative project ‘Smart Utilities and Sustainable Infrastructure Change’ (SUSIC) to develop innovative, infrastructure-based supply solutions and assessment methods for urban and regional areas in the context of dynamic system structures. HTWK Leipzig is actively working on three sub-projects, which together form Sub-project 2 of the SUSIC research project. The aim is to develop data transmission and control algorithms for intelligent agents within the low-voltage energy supply system. The outcome will be a prototype energy management system (EMS) based on an expert system, which regulates the various actors according to different operational logics in line with local or regional objectives and is tested using generic simulation models.
