Energiesprong Festival 2026 – Energiesprong Germany

Energiesprong Germany is bringing together its Innovation Day and Convention in one two-day festival dedicated to serial retrofit solutions. Taking place in Berlin in the second week of September 2026, the festival will convene professionals from construction, housing, real estate, municipalities, policy, planning and consultancy to share knowledge, shape solutions and move the market forward together. Participation is free, with further details to follow.

Across two days and two formats, the Energiesprong Festival will focus on one shared mission: advancing serial retrofit solutions and bringing them where they matter most – into neighbourhoods, apartment buildings, schools, single-family homes and everyday practice across the sector. The programme is designed for those developing innovation and scale, sharing experience, or building knowledge to get started with serial renovation.

Programme highlights

Day 1 | Innovation and solution development
A focused day for around 120 participants, featuring creation labs and collaborative sessions to further develop serial retrofit solutions.

Day 2 | Knowledge sharing and implementation
A larger gathering for around 350 participants, with curated expert talks on serial renovation, practical workshops for both newcomers and experienced professionals, campfire stations with inspiring examples, and an international stage showcasing trends and best practice.

Across both days
Participants can also expect a marketplace of innovative solutions, a wide range of networking opportunities, and, naturally, a strong festival atmosphere.
