    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

    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

    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...
