ISH Trade Fair 2027 – Frankfurt am Main, Germany

What to expect

ISH is the world’s leading trade fair for HVAC + Water and the heart of the sanitary and building technology industry, organized by Messe Frankfurt as a biennial flagship event. For the 2027 edition, the fair returns under the claim The Power of Solutions, demonstrating how individual technologies can be combined into integrated, effective systems for the building technology of tomorrow. The industry faces growing complexity worldwide, driven by high-density housing in urban areas, rising demands in residential construction and in public buildings such as schools, healthcare facilities, office buildings, hotels and data centers.

Requirements in terms of energy efficiency, resource conservation, hygiene, user comfort and digitalization are increasing rapidly, and what was once planned separately is now converging into interconnected systems. ISH addresses exactly this development by structuring its entire offering along eight solution fields that make complexity understandable and solutions tangible.

Visitors can expect the largest exhibition space for the HVAC sector worldwide, with more than 2,000 exhibitors from over 55 countries in 2025 and similar scale expected for 2027, presenting practical solutions for climate protection targets, conservation of resources through renewable energies, increasing digitalization and smart technologies.

The fair brings together the complete value chain from manufacturers, component suppliers and software developers to skilled tradespeople, planners, engineers, architects, designers, industry, trade, housing sector, energy supply, municipal institutions and facility management. The platform creates an environment in which new approaches can be put into practice more quickly and where decisions are made in the context of specific applications and projects rather than at product level alone.
