In the framework of BUILD UP, Sympraxis Team undertook for the first time on 12 October the organisation of a web roundtable, for the presentation of the report “Energy Transition of the EU Building Stock”, with representatives from the EC, the European Parliament and the market. Trying out such a format had been planned for some time and the specific event provided an excellent opportunity. The webinar was very successful, with 140 participants and a very lively discussion.
