Building technology in transition – Solutions for a better tomorrow
ISH 2025 hosted 2,183 exhibitors from 54 countries at the Frankfurt exhibition grounds. The ISH exhibition covered the latest advancements in intelligent building automation, heat generation, refrigeration, air conditioning, ventilation technologies, and sustainable bathroom design with installation solutions. This showcased sustainability at the forefront during ISH 2025.
The primary focus was on heat generation, highlighting alternative heating technologies. Exhibitors demonstrated effective heat storage, sustainable production practices, and wood-based heating. Energy efficiency was crucial for ventilation, and contemporary systems used heat recovery and evaporative cooling to reduce usage. Intelligent building control systems manage heating and ventilation processes more precisely. Manufacturers presented modern heat exchangers, touch-free fixtures, wastewater heat recovery systems, and smart water management solutions.
ISH 2025 demonstrated the combination of design, practicality, and sustainability, especially in the bathroom industry. Additionally, exhibitors showcased contemporary ideas with soft colours, 3D tiles, and resource-efficient materials that combine technology with aesthetics.
ISH Frankfurt 2025 introduced a new exhibition concept structured with eight solution areas: sanitary spaces, water-bearing systems, installation technology, heat generation, indoor air, intelligent building control, software, and HVAC + water product manufacturing. As a result, visitors found it simpler to interact with the companies and navigate the ISH trade fair.
In addition to Germany, the majority of the 163,157 visitors came from China, Italy, the Netherlands, Switzerland, France, the United Kingdom, Belgium, Poland, Austria and Türkye. 94 per cent of the visitors reported to be satisfied with the fair experience.
