The research focus on building climate control and solar construction at the Institute of Energy Technology and Energy Economics focuses on energy-efficient and climate-neutral buildings. The focus is on optimising the building envelope, heating, cooling and ventilation technology, as well as the use of active and passive solar technology such as photovoltaics, solar thermal energy and thermal insulation measures. This is complemented by heat and electricity storage systems and smart control systems (smart home). Using building monitoring and dynamic simulations, buildings are analysed and improved in terms of energy efficiency and thermal comfort. A particular focus is on research into solar thermal systems and their integration into modern building concepts.

Project description:
Together with three European and three technical universities in South Africa, this project aims to bring about change in the energy supply in South Africa. The EURYDICE project is about developing a new energy concept that taps into and uses renewable energies based on local conditions. The effects on the regional industry and economy are being researched, as well as the need for investment in distribution grids and other infrastructure measures (new investments, employment, new educational concepts, etc.). Based on the infrastructure in the off-grid regions, a training and utilization concept is to be developed that will enable the most independent and sustainable energy supply possible.

Project description:
The Energon as an office passive building is to be further analyzed in its primary energy and building climate long-term behavior and evaluated by using suitable simulation software with regard to its use in other climatic regions of the world. By comprehensively combining and evaluating all the measurement data and findings collected to date, a final classification of the overall project and an analysis of the transferability of the findings to comparable properties worldwide will be carried out.

Program name: Networking and exploratory trips of German universities and research institutions (Travelling Conferences)
Project description:
The aim of the Travelling Conference was to hold conferences at three international locations (Singapore, Mandalay / Myanmar and Daegu / South Korea) and to discuss joint research topics in the field of renewable energies. In particular, innovative and individual concepts were developed there as a basis for future research cooperation.
At the Solar Energy Research Institute Singapore (SERIS), the topic of photovoltaic supply for the energy transition was discussed and joint research ideas developed. In Korea, the main topic of discussion was the reliability of power grids and approaches to increasing this via digital grids. At Mandalay Technological University (MTU), talks were held on climate-specific topics in the field of building technology, such as cooling buildings and green campus projects, and joint research questions were discussed.

Project description:
Under the framework conditions of the energy transition in Germany, it is crucial that the so-called "zero-energy house" or "Efficiency House Plus House" not only works on paper but also in reality. This requires further energy savings, but these can hardly be achieved in reality by improving the building shell and systems technology alone. There is great potential in intelligent, cost-effective and energy-efficient home automation with a long-term monitoring option. The ability to manage and regulate blind and shutter control, heat generation, heat distribution, the use of photovoltaic electricity and the use of weather forecasts within one system means that this system can serve as a "house manager" for the energy-efficient operation of a new building. Furthermore, it is being investigated how air-source heat pumps can be optimized in single-family homes so that calculated annual performance factors (APF) can be realistically implemented in practice. Basic information about the efficiency curve of a heat pump (development of the COP in the respective operating phases start, partial load operation, full load operation) is to be obtained in order to be able to evaluate the effect on energy efficiency through frequent cycling. This has a significant influence on the decision regarding the associated storage system: does it make more sense to install a pure drinking water storage tank or should it be possible to buffer the heating water? The sensible integration of the photovoltaic system into the overall system will be another focus of the project. There is potential here in a possibly feasible setpoint change for surplus self-generated electricity for intermediate storage and grid relief. The realistic proportion of self-consumption that can be expected when operating an air source heat pump in conjunction with a PV system is to be determined. In addition, the energy concept is to be supplemented by an electricity storage system.

Project description:
In times of an energy supply network that increasingly integrates renewable energies, it is of great importance to consider these energy sources in their entirety and to develop suitable solutions for a reliable and sustainable energy supply in the building sector. The iHEM project focuses specifically on photovoltaics and solar thermal energy in combination with micro-CHP and storage systems for thermal and electrical energy in private households. Complex simulation models of existing and new buildings are being developed for this purpose. By linking a building simulation model with other models, such as solar thermal and PV systems, heat storage, batteries, fuel cells, etc., to create an overall system simulation, the energy supply system can be dimensioned by specifying a defined scenario and associated operating mode. The simulation can also be used to determine key figures such as self-sufficiency and self-consumption rates, which enable the comparison and benchmarking of a wide range of energy system constellations. In this context, a demonstrator system consisting of heat and electricity storage, solar thermal and PV systems together with a micro-CHP (fuel cell) is being set up in Ehingen an der Donau and supplemented by a comprehensive monitoring system.
