Energy monitoring in heating and plumbing systems to improve energy efficiency
To date, building services systems, buildings and users have each achieved significant energy-saving successes 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: 10/2024 – 09/2026

Energy Strategy for the Leipzig Port Office
The building was constructed in the late 1930s as a temporary storage facility and converted into a laboratory and administrative building in the mid-1960s. It is situated in Lindenauer Hafen and, together with the other storage buildings, forms a heritage site.
- Currently heated by oil, with an annual consumption of 30,000 litres
- Property available to let, comprising a combination of office, storage and workshop space.
- Focus on future refurbishments (heating, alternative energy generation, smart resource management) with a sensible approach to bespoke measures.

Energy-efficiency refurbishment
Scientific consultancy on the energy-efficiency refurbishment of the sports hall at HTWK Leipzig
- Use of battery storage systems
- E-mobility for electric vehicles and e-bikes
- Implementation of a smart energy management system to control energy flows
- Rainwater management and the use of cisterns for outdoor watering and toilet flushing
- Use of reusable materials (Cradle to Cradle, Madaster)
- Information on funding opportunities, e.g. federal funding for energy-efficient buildings and the BAFA grant
- Integration of PV modules into BIM (light transmission, supporting structure, U-value)
Project partner: SIB Leipzig
Project duration: 04/2023 – 12/2025
Extension of the Nieper-Bau wastewater treatment plant
The building energy technology laboratory area includes a wastewater tower which is to be upgraded for laboratory experiments and research projects focusing on the following areas:
- Assessment
- Implementation of an additional drainage system. This must include a gravity-fed drainage system, which will enable independent measurement and analysis of flow rates.
- Implementation of a domestic hot water system with circulation to enable temperature measurements using disruptive sensors. This system is intended to form the basis for monitoring temperature control in domestic hot water systems in cooperation with industry partners.
Project partners: Geberit, Georg Fischer, Mehrwert für Gebäudetechnik, among others.
Project duration: 04/2023 – 12/2024
