Regional trade fairs in Germany are highlighting advancements in construction, electrical technology, and sustainable energy solutions. The 36th RoBau exhibition, scheduled for September 25–27 at HanseMesse Rostock, serves as a platform for private home construction, modernization, and energy technologies in northeastern Germany.

As part of the RoBau event, companies such as Rheingas plan to present integrated energy solutions. These demonstrations include the coordination of technologies like heating systems, heat pumps, photovoltaics, solar solutions, and energy management systems to create efficient building supplies.

In Thuringia, the ninth Energieimpuls Regionalmesse Ost (RMO) recently concluded at Messe Erfurt. The event attracted approximately 4,500 professional visitors from the craft, industry, and facility management sectors, featuring 165 exhibitors focused on electrical installation, intelligent building technology, and renewable energy applications.
