The 4DH Strategic Research Centre, the RE-INVEST project and Aalborg University invited researchers and experts from industry and businesses to the 3rd International Conference on Smart Energy Systems and 4thGeneration District Heating. This year’s conference took place from 12-13 September 2017 in Copenhagen.

The aim of the conference was to present and discuss scientific findings and industrial experiences related to the subject of Smart Energy Systems based on renewable energy and future 4th Generation District Heating Technologies and Systems (4GDH).

This year’s conference was held at the The National Museum of Denmark.

The conference dinner took place at the restaurant Grøften. Grøften is located in the historic Tivoli Gardens and is one of Tivoli’s oldest and most traditional restaurants, with a history that goes back to 1874.
