23–26 May 2023
Šamorín, Slovakia
Central & Eastern European Energy Efficiency Forum
Not your average conference
The Central and Eastern European Energy Efficiency Forum came to Šamorín, Slovakia, for its 2023 edition — two and a half days of sessions focusing on the energy efficiency of buildings. The main topics addressed at the event were energy security, the rebuilding of Ukraine, and EU policy, including the REPowerEU plan and the Fit-for-55 package.
Programme structure
The C4E Forum was a time-efficient event: it started late on the Tuesday and finished early on the Friday with departures. That meant two and a half days full of different types of sessions, all focusing on energy efficiency — from high-level plenaries to panel sessions on practical topics, with plenty of time for networking.

Programme highlights
Pre-conference events
For those arriving earlier on the first day, the pre-conference events made good use of the time on the topic of energy efficiency.
Plenaries
High-level speakers from international institutions, CEE countries and the EU presented and discussed regionally relevant subjects.
Panel sessions
Sessions on the event’s main topics: energy security, the rebuilding of Ukraine, and EU policy — the REPowerEU plan and the Fit-for-55 package.
Sponsor workshops
60-minute events prepared and hosted by sponsors on an important, relevant topic.
Poster sessions
A new idea for the 2023 edition: presenting a topic by means of a poster.
Controversial ideas session
A session designed to spice things up with a little controversy, rather than preach to the choir.

Venue 2023
The C4E Forum 2023 took place in the central location of Šamorín, near Bratislava, Slovakia, at the X-bionic Sphere — a large accommodation and sports complex, beautifully located on the banks of the Danube River.
