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 […]
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 […]
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 […]
In his keynote speech at Eurosun 2020, Dr Andreas Hauer talked about the different roles that heat storage could play as part of a whole systems approach to energy policy. […]
PV-thermal installations are extremely versatile systems, and their manufacturers can cater to a wide variety of customers, single- and multi-family building owners, hotels, swimming pools and even production facilities among […]
In the last decade, Denmark, China, Germany and Austria played a leading role in the deployment of large solar thermal systems around the world. What country-specific factors helped these four […]
Solar thermal is increasingly used to provide district heat around the world. In 2019, the market grew by about 170 % in Denmark but also expanded in other countries, such […]
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 […]
How much does it cost to construct, run and maintain a Nearly Zero Energy Building? What energy efficiency and renewable options could work best for a given project? Answering these […]
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 […]
