Energieeffiziente Gebäudetechnik

While our society is willing to go for zero energy and plus energy buildings, our buildings still have to be prepared for the use of 100% renewable energy.

As a result, innovations in building technology and grid-responsive operation of buildings are urgently required. A central challenge is the optimization of facility and controlling in the technical building equipment for decreasing energy demands. This includes especialy lower heat flow densities for heating and cooling.

The E2G group at Offenburg University conducts research in the field of technical building equipment with a focus on heating and cooling with thermo-active construction components, ventilation technology and indoor air flow, façade-integrated building technology, and energy system technology for buildings.

Economic viability, energy and resource efficiency as well as workspace and living quality are the focus of metrologically oriented studies.


Building Information Modeling, or BIM, is used for the optimized planning and technical documentation of buildings through all construction and operational phases. Still, BIM methods are only slowly finding their way into the planning, implementation and operational phases of building technologies (German: Technische Gebäude Ausrüstung, or TGA).
In this project, we are developing BIM methods for the commissioning and operational optimization of TGA systems and demonstrating commissioning with IoT and BIM on a low-energy building, the Regional Innovation Center for Energy Technology at Hochschule Offenburg (RIZ Energie). BUiLD.DIGITiZED thus provides impetus for the broad application of BIM methods, from design planning to implementation to commissioning.

The µGRiDS simulation model enables the operational analysis of small-scale building energy systems , decentralized energy network systems and their decentralized control based on price signals. The optimal operating strategies are derived based on a real system and include the engineering know-how about the individual components. Existing models can also be used to develop and implement energy systems of different sizes, for example comprising several combined heat and power plants or heat pumps. In addition to the price signal, the heat and cooling load will also be taken into account in the optimizer.

The energy-system transition facilitates more renewable energies and decentralization. The resulting increase in diversity, comprehensive participation and complexity of (interconnected) energy generation require extensive transformation of the infrastructure for energy distribution and storage. To guarantee a both secure and inexpensive supply, solutions on the prosumer level with sector coupling are being discussed. Through intelligent grid connection and control of these systems, the flexibility gained can be used to support the grid.

We are developing supervisory, grid-supportive control algorithms and operation management strategies for sector-coupled, hybrid energy systems, providing heating/cooling and electricity with different – primarily renewable – final energies. The energy prosumers are designed for neighborhoods and districts with a nominal electrical output of approx. 1 MW, to provide heating/cooling and electricity as efficiently as possible with a very high proportion of renewable energy sources. The coordinated system optimization of the prosumers is demonstrated with a supervisory operation management strategy for five trans-regionally distributed energy islands.


The project is funded by INTERREG V Oberrhein 3.15 and Wissenschaftsoffensive 2018.

University and vocational students work together on transforming a shipping container into an information point illustrating elements of building technology and their respective functions.

If a comfortable atmosphere in an office space is also achieved in an energy-efficient manner, it has a positive effect on both the working and the global climate. However, the handling of corresponding building technologies has to be learned. The interdisciplinary KLONG project set the task of providing users with the necessary specialist knowledge by producing smart educational films.

In the joint project MOSAIK, an innovative urban climate model is developed which should be able to simulate the urban microclimate in large cities like Berlin with a spatial resolution of less than 10 meters and be a user-friendly tool for urban planning. Hochschule Offenburg’s part is developing the building model, which calculates the indoor climate and the energy demand of the individual building zones depending on their specific parameterization. This primarily concerns the building physics of the facade, the use of the space/building, user behavior, control strategy/operation management, and the technical equipment. The agreed driving variables are the facade and boundary layer temperatures as well as the local irradiation and wind speed (if necessary with wind direction) from the urban climate model. To minimize the computation time and allow for less complex coupling between space and urban climate via the facade temperature, the building model is based on an analytical solution of the Fourier heat conduction equation and the energy balance of the space.

The provision of cooling from waste heat is a very energy-efficient option. A large potential for adsorption chillers lies in the capacity class below 10 kW cooling. Here, industrial waste heat or micro-cogeneration plants can be considered as a source of power. In a laboratory setup at INES and a model-based, theoretical investigation, a trigeneration system with a hot and a cold storage tank combined with a conventional reversible heat pump  is evaluated in terms of energy efficiency and grid-supportive operation.

Internal financing, cooperation project, DENE doctoral research group.

This project provides the foundations for the energy-economically optimized operation of small CHP systems based on adsorption chillers.

Many decentralized regions in the world suffer not only from a shortage of clean drinking water, but also from a lack of infrastructure and thus a shortage of energy sources. About two billion people globally have neither electricity nor access to clean drinking water. Using solar energy to operate water treatment plants and desalination systems could provide a major solution to the problem. What is needed is an energy-autonomous, robust and, if possible, maintenance-free process that ideally covers the entire production chain from raw water extraction and purification to disinfection and distribution. SolarSpring GmbH (SSP) systems used for this purpose are essentially solar thermal driven membrane distillation (seawater desalination), ultrafiltration (freshwater treatment) and UV disinfection (sterilization), with the electricity required for operation being provided by photovoltaics. Typical system sizes vary from 150 L to 20 m³ of drinking water per day, although larger overall systems can also be produced thanks to a modular design.

Measurement evaluation of facade-integrated parapet units (incl. air conditioning) and decentralized ventilation units in comparison to window ventilation and centralized ventilation units with special consideration of indoor air flow and energy efficiency.

Industrial project with several project partners, cooperation project with Fraunhofer ISE.

Further development of predictive methods aiming at adapting to different room characteristics. By using modern methods (e.g., neural networks, artificial intelligence, model-based control), algorithms with the ability to learn can adapt to differently used zones in the building independently. Such methods can also react automatically to changes in room characteristics caused by fluctuations in use.

In the two subprojects, “Basic Principles of Building Physics and Energy Economics” and “Building Model for Integration into The Forecast Models of the German Weather Service”, the needs for action in the area of "Urban Climate / Microclimate / Indoor Climate” are identified from an energy-economic perspective. On the basis of a simulation model it has been possible to quantify, at least approximately, the interaction between buildings and urban climate.
This project also includes support (Advisory Board) for the “Sonderforschungsbereich 1736: Urban Climate and Heat Stress (UCaHS)”of the DFG, the WHO working group “Health and Climate Change,” and the “Weiterentwicklung der Testreferenzjahres-Datensätze”.
