House & Energy (Haus & Energie) Mannheim

The "House & Energy" (Haus & Energie) Fair in Mannheim is your annual opportunity to gain first-hand, practical insights into all key topics related to building, renovation, living, and home technology. Organized by the experienced MG Messebau GmbH, based in Mannheim (well-known for its exhibition stand construction at the Congress Center Mannheim Rosengarten, the Mannheim Maimarkt, and at venues across Germany), the event is aimed at both industry professionals and interested homeowners – a clear advantage for anyone seeking both expertise and inspiration.

The venue is the PX-de-Dom Exhibition Center in Mannheim-Sandhofen. Sandhofen, a district in the northern part of Mannheim, is easily accessible by public transport and offers designated parking spaces on-site.

At its core, the fair is not about merely walking through exhibition halls, but about "experiencing and deciding". Visitors step into an event where products such as photovoltaic systems, heating technologies, window solutions, and smart home innovations are not only on display but can be experienced live, touched, and discussed directly with experts on-site.

Distinctive features of this trade fair include compact themed areas with live demonstrations and short presentations, independent information on financial incentives, and a guided visitor layout that allows for quick comparison of different solutions. This transforms the event from a mere source of inspiration into a true decision-making tool.

The fair’s orientation is primarily regional with national significance: in Mannheim-Sandhofen, a platform is created that is locally rooted while showcasing technologies and products that are in demand across Germany. The location thus makes it both tangible and accessible – featuring regional specialists – while remaining relevant for larger investment and modernization projects.

Thematically, the focus lies on building, renovation, living, and energy efficiency. Exhibitors present solutions in the areas of photovoltaics, heating, windows, smart home systems, and interior design. The accompanying program and visitor experience go hand in hand, featuring live demos, personal consultations, and on-site subsidy checks.

Mannheim itself – rich in history, modern in outlook, and centrally located within the Rhine-Neckar region – offers the perfect backdrop for a trade fair centered on future-oriented topics such as energy efficiency, smart homes, and sustainable living. The city’s mix of tradition and technology provides an ideal setting for exhibitors and visitors to meet on equal footing.

So, if you are looking for concentrated expertise, tangible solutions, and direct consultation on all aspects of home, energy, and technology – whether as a professional or an end user – the House & Energy Fair Mannheim is an event you simply shouldn’t miss.

The House & Energy (Haus & Energie) will take place on 2 days from Saturday, 16. May to Sunday, 17. May 2026 in Mannheim.
