IEA EBC – Annex 83 – Positive Energy Districts
According to the European Commission, 100 PEDs are to be created in Europe by 2025. In order to realize these districts, energy efficiency of the buildings must be improved. Moreover, local energy flows must be cascaded by using waste energy, and low-CO2 energy generation technologies must be used to cover the remaining energy demand. PEDs […]
Build Re Use – 100 percent re-use and recycling with regard to short service-life buildings
Primary resources for construction are limited. Thus, their re-use is necessary and worthwhile. Re-using building components not only protects ecosystems from mining and waste disposal but also reduces dependence on raw materials. Currently, re-use of components like beams, windows and suspended ceilings does practically not occur, even though it is technically feasible.For some buildings, short […]
Exploration Reallabor Weiz plus – Reallabor climate neutral region Weiz plus
In this exploratory study, the relevant questions for the potential establishment of a real laboratory in the Weizplus region, which aims to supply the region 100% with renewable energies by 2030, are to be clarified with the involvement of the regional innovation ecosystem. The content-related technological focus of the activities of the future real laboratory […]
PEC-Solarreactor – Solar reactor for photo-electrochemical recovery of hydrogen from wastewater
Hydrogen is an important energy carrier for achieving the set climate targets. As it is currently mainly produced from fossil fuels, great efforts are being made to produce hydrogen using renewable resources. However, the potential of renewable electricity (e.g. PV /surplus electricity) is limited and far from sufficient to achieve decarbonization in a sustainable way. […]
Hybrid LSC – Management of trans sectoral energy carriers for local sustainable communities
The Hybrid LSC project will analyze how EnCos can be motivated for collective actions beyond sharing (electric) energy and how Energy Community Operating Models can be developed for sustainable EnCos depending on the region (urban, rural), energy and resources network (e.g. water infrastructure) potential. The novelty of this project is to demonstrate the use of […]
HarvestIT – Advanced monitoring of large-scale solar thermal plants with open-source software solution
Background: Large-scale solar thermal plants (> 500 m2 collector area or 350 kW power) are a cost-effective technology for providing renewable heat. The construction of new plants requires a high initial investment, which is repaid over the operating life by the selling the generated solar heat. Thus, the technology is only economically attractive for customers […]
FlexModul – Demonstration of a Modular Solid Sorption Heat Storage System
Due to their considerable flexibility and balancing potential, heat storage systems will in future play an important role in the integration of renewable energy sources and waste heat. Thermo-chemical storage systems based on solid sorption have the potential to achieve three to four times higher energy densities in comparison with water storage systems. They are […]
AbSolut – Absorption technologies as solutions for sustainable district heating and cooling
In Austria, more than 2.1 million people and numerous businesses and companies are currently supplied with energy by means of district heating [1]. Currently, an energy volume of 19 TWh/a is provided to consumers, with expected growth rates of 0.8% per anno in the next five years. This demand is currently being met through investments […]
MoreStore – Know-how for innovative integration and assessment of large-scale thermal energy storages
The demand for energy storage will rise significantly on our way to fully decarbonized energy systems due to increased use of renewable energy sources and their non-continuous supply. In particular, large-scale hot water thermal energy storages for local and district heating networks, with volumes of up to 100,000 m³, will play a key role in […]
GIZ_Consulting_Lviv – Support for the development of the district heating network in Lviv, Ukraine
As most post-soviet countries, Ukraine has a long history in using district heating (DH) and a widely spread district heating infrastructure in all major urban settlements. Natural gas still remains the dominant energy source for the district heating sector, while the interest in renewable heat sources is continuously rising. The European Union, many other countries […]
