The principle of the 2-WAY SUBSTATION (2WAY SST) is to return unused energy to the supply network with the highest effi­ciency. The objective is to create a system with high feed-in temperature from solar energy.

For that purpose, 2WAY SST uses Compact Heat Exchangers, Variable Speed Pumps, Controlled Valves and Controlled System. At CEA-INES facilities in South-East France (Le Bourget du Lac), the assembling of the 2WAY SST is in progress.

Two out of three heat exchangers (H1 & H2) and pumps (P1 & P2) have been already installed in June. An extra loop emulating the sanitary loop of the building is being set up, with the pressure tests already being passed.


From 10th to 12th July 2019, the International Conference on Energy and Cities (ICEC) was held at the University of Southampton, UK. We are happy that the THERMOSS project was presented with both an oral presentation and a conference stand.

The oral presentation titled “English Domestic Occupancy Profiles” was led by Victoria Aragon from University of Southampton on the 11th July during the Low Energy Building Session. It focussed on THERMOSS-funded research into domestic occupancy profiles. Our THERMOSS UK demo sites were also presented as case studies for energy and occupant behaviour monitoring.

The conference was a great opportunity to meet fellow energy-efficiency enthusiasts at our stand and we look forward to the next event.
