During the early December knowledge exchange trip the CVUT SPARCS team visited the Norwegian city of Trondheim with its positive energy district (PED) in Brattørkaia. The city together with the university (NTNU) take part in the sister H2020 +CityxChange project. The Trondheim Brattørkaia complex includes one of the remarkable energy positive buildings: Powerhouse Brattørkaia, an office building designed by Snøhetta architects and developed by Skanska with 18,200 m2 gross internal area. It has been labeled as BREEAM Outstanding,

The PED in Trondheim has currently been entering its final implementation stage. The teams from CVUT and Trondheim municipality discussed practical lessons learned of creating local energy market that serves as an enabler to reaching PED ambition. The CVUT presented the planned PED in the Czech city Kladno as well as other relevant case studies. The teams agreed to share further information on currently developed PED Database by PED-EU-NET COST Action and other relevant activities.

Together with NTNU and SINTEF teams the visit continued to Zero Emission Buildings (ZEBs) that have been built as research facilities during the recent years in the vicinity of the university campus. The new building of SINTEF and NTNU is a timber structure serving as a ZEB Office Living Lab. It is 4 stories high and 2000 m² located in Trondheim. Leading PED researchers from both local organisations took part in a joint workshop focusing on PEDs and district heating systems.
