Haus-Bau & Energie Ilsenburg

Since its launch in 2004, Haus-Bau & Energie in Ilsenburg has established itself as a leading regional consumer exhibition. It focuses on the key themes shaping the future of the built environment: sustainable construction, energy-efficient refurbishment and modern, comfortable living. The name reflects the full spectrum of services on offer – from residential construction and architectural planning to building services engineering and intelligent energy solutions. In short, it covers everything required to create homes that are durable, retain their value and are fit for the future. Held annually at the Harzlandhalle in Ilsenburg, the event brings together professional expertise, innovative products and tailored advice under one roof.

The exhibition is organised by Heiko Klein Messen und Ausstellungen, an experienced regional event organiser specialising in consumer-oriented information and advisory formats.

The show spans the entire construction and refurbishment value chain. Core themes include new-build and renovation concepts, high-performance building envelopes, advanced insulation and construction materials, window and door systems, roofing and façade technology, as well as timber construction and prefabricated building methods. The programme is complemented by heating and plumbing solutions, pellet and heat pump systems, photovoltaic and solar thermal installations, battery storage, and smart control and home automation systems. Visitors will also find information on finance and funding schemes, property services, interior fit-out, comfort solutions, conservatories, awnings, carports and stove and fireplace systems. Energy-efficient retrofit measures and indoor environmental quality are also covered. Attendees can compare products and speak directly with contractors, energy consultants, architects, banks and developers from across the construction, building services, energy, property and financial services sectors.

Haus-Bau & Energie is primarily aimed at private individuals planning to build, refurbish or purchase property. Increasingly, it also attracts trade professionals from construction, design and energy consultancy who wish to keep abreast of regional market trends and develop new business contacts. Expert presentations, practical advisory services and themed special exhibitions are regular highlights of the event.

Thanks to its long-standing presence, the exhibition has become a fixture in the regional events calendar and plays an important role in strengthening economic networks within the Harz region. The Harzlandhalle provides a modern, easily accessible venue with ample parking facilities. It is conveniently located close to the B6 federal road and within easy reach of the A36 motorway. As such, Haus-Bau & Energie is not only an information platform but a central meeting point for anyone looking to shape their home in the Harz and across Saxony-Anhalt in a sustainable, efficient and value-conscious way.

The Haus-Bau & Energie will take place on 3 days from Friday, 27. March to Sunday, 29. March 2026 in Ilsenburg.
