ISH Energy: Everything for the energy transition in buildings

28 Feb 2023

Specific solutions for achieving climate-protection goals in the building sector will be on show at ISH 2023 in Frankfurt am Main from 13 to 17 March. In the ISH Energy section alone, over 1,100 exhibitors, including the market leaders, will present their innovations for the heating, air-conditioning and ventilation segments, as well as the intelligent home and building automation market, in Halls 8 to 12 of Frankfurt Fair and Exhibition Centre. ISH Water occupies seven exhibition halls in the eastern section of the Exhibition Centre and brings together around 900 exhibitors.

ISH, the world’s leading trade fair for HVAC + Water, opens its doors once again in Frankfurt am Main from 13 to 17 March 2023. There, artisans, planners and architects, suppliers, representatives of the wholesale trade, the real-estate business, the building sector and politics can inform themselves about current and future developments in the field of sanitation, heating and air-conditioning technology. At this, the leading international platform for the energy transition in the buildings sector, the industry presents its market-ready solutions for a sustainable future. Altogether, some 2,000 companies from 54 countries are exhibiting their latest products and solutions for utilising renewable sources of energy, sustainable water consumption and clean air.

The focus of social discussion has shifted to the top themes of ISH Energy. Today, the spotlight is on products and solutions for achieving climate-protection goals in buildings, the decarbonisation of the heating sector and the security of supply. Stefan Seitz, Director of ISH Brand Management at Messe Frankfurt, is looking forward to the sector’s highlight of the year: “The ISH Energy section embraces the entire technical spectrum: the exhibitors, who include the world’s leading manufacturers, present solutions designed to meet the challenges of our time, i.e., climate protection, sustainability and supply security. Following the pandemic-induced interregnum, they want to show their latest innovations and are looking forward to the trade fair. At last, it is once again time to explain the products and solutions at the fair and to conduct personal discussions.”

Altogether, some 1,100 exhibitors are presenting their new products within the framework of ISH Energy in Halls 8 to 12. One of the top themes there is the heat pump in all its versions – an important component for the implementation of the energy transition. Naturally, the spotlight is also on many other solutions, e.g., CHP installations, fuel-cell heating systems, photovoltaic and solar-thermal systems, hydrogen-capable condensing boilers, wood-based systems, such as pellet heating systems, digital solutions, home ventilation with heat recovery and energy-saving automation.

The ISH Contactor provides an up-to-date overview of all exhibitors and their product portfolios. Via a special-interest filter, the Contactor can also be used to gather information about the most important issues facing the sector. Additionally, the Contactor can generate lists of manufacturers offering products and solutions for specific subject areas. The themes of ISH can be filtered according to:

  • Solutions for sustainable energy storage
  • Solutions for digital networking in buildings through energy management systems
  • Solutions for efficient process optimisation

As at previous editions of the fair, Halls 9.0 and 9.1 provide the setting for heat-distribution solutions while the focus in Hall 8 is on cooling, air-conditioning and ventilation technology.

The products and services offered by the exhibitors are flanked by a comprehensive programme of events. With a wide-ranging series of lectures, the Energy Hotspot takes up the most important issues in the heating sector and, simultaneously, provides a central meeting place for the sanitation, heating and air-conditioning trade. Moreover, the Hotspot puts the spotlight on energy storage and energy management. In the Wood Energy Hotspot, the focus is on the domestic and almost CO2-neutral energy resource wood. Here you can find out everything worth knowing about wood-based heating systems, the associated technical components and about wood as an energy source. Additional opportunities to gather information, as well as to participate in training events and networking, are offered by the Indoor Air and Building Technology Hotspots.
Promising solutions by newcomers are to be found at Start-up@ISH.
