Improved design for giga-size pit heat storage

Denmark’s cost-effective, tried-and-true seasonal pit heat storage concept needs to be modified if it is to be implemented across Europe, since district heat temperatures are higher and groundwater may be only 5 to 15 metres from the surface. The members of research platform Task 55 (...

Solar houses: above 95 % solar fraction is possible

Between 2014 and 2019, the Austrian Climate and Energy Fund supported the construction of over 100 solar-heated houses, 19 of which were monitored following completion. Regardless of whether it was a lightweight or a brick house that was put up, the rooftop or facade collector system...

Benefits of 4G and 5G heat networks

Fourth-generation heat networks, which operate at about 60 °C, reduce heat losses, extend pipe life and create the best conditions for clean energy use. The photo shows one of these grids, which has been running in a neighbourhood in Villach, southern Austria, since the beginning of 2018....

Solar Energy Buildings to make cities fit for the future

Buildings account for around 40 % of the world’s primary energy consumption. Hence, they are the number one cause of resource consumption on earth. Because not every urban neighbourhood all over the world can be connected to district heating, local governments and building owners may need...

Christoph Brunner: Solar heat for water purification and metal recovery in industry

Water and energy are the most important resources globally. The term ‘water-energy nexus’ underlines their close connection, and the phrase has become increasingly popular with international environmental organisations. In the interview carried out at the SHC 2019 conference in Santiago de Chile,...
