Efficient Heating - A Systematic Study and Evaluation of the Economic and Environmental Sustainability of Solar-Based Renewable Heating Systems Compared to Alternative Systems
Heating residential buildings has a significant impact on the sustainability of the energy supply and represents a major cost factor. To optimize heating in line with future climate policy goals, various technologies and combinations thereof are available, with a particular focus on the use of renewable energy sources. -
EKUS hoch i - Energy Conservation and Climate Protection Through Smart Room-by-Room Solutions in the University of Stuttgart’s Buildings
The “EKUS hoch i” project is investigating how modern information and control technology can be used to reduce individual, space-specific energy consumption and lower greenhouse gas emissions in public buildings while maintaining comfort. -
fronTherm - Facade heating and cooling unit for the phased retrofitting of existing buildings
This project is developing an innovative system that enables the simultaneous retrofitting of a building’s envelope and heating system without requiring major work inside the building. It is designed to facilitate the efficient use of solar and heat pump technology and to be operated error-free even by semi-skilled workers. It could, in a disruptive way, enable drastically increased retrofitting rates and thus make a significant contribution to solving the climate crisis. -
GeoSto - URBAN ARENA – Design of a climate-neutral heat supply system combining deep geothermal energy and seasonal thermal energy storage, using Neustadt-Glewe as an example
Using Neustadt-Glewe as a case study, a simulation study examines how deep geothermal heat can be combined with a seasonal thermal heat store. If necessary, it can be supplemented by other renewable energy sources to enable a full decarbonization and the expansion of the district heating network. -
HEELP - Improving Energy Efficiency and Comfort in Residential Buildings by Integrating Energy Models into an Interoperable Smart Home Platform
The goal of this research project is to develop a solution based on smart home devices and technologies that, on the one hand, raises room users’ awareness of health and energy conservation and, on the other hand, can be easily integrated into residents’ daily lives to support them with recommendations for action or automated control actions. -
HoVAG
Large-scale heat pumps will play a central role in the climate-neutral heat supply to industry. However, the use of conventional refrigerants is in question due to regulatory requirements (F-Gas Regulation, impending PFAS ban). Future-proof alternatives are “natural refrigerants” such as ammonia. The HoVAG research project aims to develop shell and tube heat exchangers with new high-performance tubes optimized for the evaporation of ammonia. These enhanced heat exchangers will increase the efficiency of large-scale ammonia heat pumps, reducing the required refrigerant charge. -
innoBeLs - Development and assessment of innovative container concepts for latent heat stores in cold solar heating networks
The aim of the "innoBeLs" project is the development and implementation of innovative economically and ecologically beneficial container concepts for latent heat storage for commercial use in solar cold district heating networks. Currently, latent heat or ice stores mainly use cost-intensive concrete tanks with two heat exchanger coil loops. Their production is relatively energy-intensive, leading to significant greenhouse gas emissions. In contrast, the newly developed innovative container concepts aim to reduce environmental impact and resource consumption by at least 50 % and cut costs by at least 20 %. -
integraTE-XL
The aim of the “integraTE-XL” project is to establish technically and economically attractive systems for thermal and electrical energy supply using PVT collectors and heat pumps in existing large apartment buildings and commercial properties in order to achieve significant long-term CO₂ savings. The implementation of PVT systems in the difficult market environment of renovation, through knowledge transfer and the development of planning tools and a “PVT chatbot,” is intended to remove barriers in the renovation market and support the spread of this technology. In parallel, several PVT systems will be examined using measurement technology, products will be tested, and the findings will be presented nationally and internationally. -
MultiHeat
By means of an extensive simulation study it is particularly investigated how locally available renewable energy sources such as solar energy and wind energy can be used in combination with a seasonal heat store to provide a climate-neutral heat supply for existing villages with approximately 2,000 inhabitants and predominantly residential development. -
NGEE26 - Next Generation Energy Experience 2026
Die Next Generation Energy Experience ist unser Nachwuchsprogramm und besteht aus zwei Komponenten: Der Next Generation Energy Challenge und dem Next Generation Energy Day. Ziel des Programmes ist es, junge Menschen für den Ingeneiursberuf und speziell unsere Forschungsbereiche Gebäudeenergetik, Thermotechnik und Energiespeicherung zu begeistern, Interesse für das Thema zu wecken und zu vertiefen. -
ProLuft - Entwicklung eines zukunftsfähigen Luftheizsystems mit Propan für eine energieeffiziente und flexible Wohngebäudeklimatisierung
Klimafreundlich heizen mit Luft und Propan -
RoBewEnt – Robuste Bewertung von Entrauchungssystemen in Hallen und Atrien unter unsicheren Randbedingungen
In diesem Projekt sollen parallel 2 Berechnungsansätze (analytisch mit Kennzahlen sowie stochastisch mit Monte-Carlo-Simulationen) zur Rauchausbreitung und Rauchgasschichtung in typischen Gebäudegeometrien entwickelt werden, um mit diesen Erkenntnissen ein für die Anwender (überwiegend KMU) einfach nutzbares Berechnungstool speziell für komplexere Geometrien ableiten zu können. Mit den Verfahren und dem Berechnungstool sollen natürliche und maschinelle Entrauchungssysteme ganzheitlich bewertet werden können. -
SKARK - Smarte Konzepte zur Integration von Abwärme und kosteneffiziente Kühlung von Rechenzentren: Synergien zwischen Rechenzentren, Kaltnahwärmenetzen und Eisspeichersystemen
Das Projekt entwickelt ein innovatives Gesamtkonzept zur effizienten Kühlung von Rechenzentren und zur sinnvollen Nutzung der entstehenden Abwärme durch deren Einspeisung in ein kaltes Nahwärmenetz. -
SolKaN2.0 - Second generation solar cold district heating
The aim of “SolKaN2.0” is to develop a new or second generation of solar cold district heating systems in which water is used as the heat transfer medium instead of a water-antifreeze mixture, as is done today. By this new development, the investment costs can be reduced by more than 20 % and operating costs by around 10 %. -
TurboKon-H2O
Entwicklung eines innovativen energieeffizienten Verfahrens zur kontinuierlichen Wassergewinnung aus feuchter Luft durch heterogene Kondensation an Aerosolpartikeln mit Hilfe von Turbomaschinen -
WATmosfAIR - Entwicklung einer Erschließungsstrategie für die solar-sorptive Trinkwassergewinnung aus der Atmosphäre in ariden Gebieten
Etwa jeder dritte Mensch auf der Erde hat keinen Zugang zu sauberem Trinkwasser oder muss extrem weite Strecken für dieses zurücklegen. Besonders entlegene Regionen mit aridem Klima sind von Trinkwasserknappheit betroffen. Damit geht besonders für Mädchen und Frauen eine soziale Benachteiligung hervor, da meist sie es sind, die für die Wasserbeschaffung zuständig sind und dadurch keine bzw. weniger Zeit für Bildung und Ausbildung haben.
