ISH is both the flagship and the heart of the sanitary and HVAC sector. As a unique driver of innovation, it is the place where solutions for a sustainable future become tangible.
Top Themes ISH Energy
Never before have we been made so aware of the importance of a secure energy and water supply. But above all: what consequences too great a dependence on individual energy sources and suppliers can have. The keywords here are energy self-sufficiency, security of supply, drinking water hygiene and diversification of energy sources towards an even higher share of renewable energies. Like hardly any other event, the ISH takes up precisely these topics and, for 2023, sets its sights above all on solutions for achieving the goals of the Paris Climate Protection Agreement, but also on the importance of intelligent energy management that links the heating and mobility sectors. Not to be forgotten: greater electrification and the associated topic of energy storage, as well as the ever-growing importance of hydrogen as an energy carrier.
Solutions for Heat Transition and Climate Protection

REPowering EU: Technical solutions for the building sector
For the building sector, ISH will show the technical solutions described in the EU's REPowering Strategy. The aim is to reduce the EU's dependence on Russian gas.

Energy Efficiency & Sustainability

Building New Energy
As the movers and shakers of the energy transition, the building technology sector makes a key contribution to positive developments in climate change with its products and services. The companies include established manufacturers, wholesalers and specialist trade businesses as well as freshly founded start-ups.

Electromobility and building automation: pure efficiency!
Electromobility is almost inconceivable without buildings because, in the future, more and more workplaces, supermarkets, carparks and other non-residential buildings will provide charging options. Given the high power requirements, building-energy management is essential to ensure the controlled smoothing of peak-demand loads.

Ventilation with heat recovery: using heating energy efficiently
Demand-controlled ventilation systems with heat recovery can contribute significantly to the efficient use of heating energy. They keep ventilation heat losses low, as a large part of the energy from the extract air is transferred to the supply air.

Indoor-Air Quality
The topic of air, which is anchored in the ISH, also makes an important contribution to the overriding goal of CO2 reduction and energy saving. Air has always been the most important food for people, yet in the past less attention was paid to this topic in buildings. The last two years have now shown everyone how important a hygienic air supply is in buildings, as it minimises health risks and strengthens performance and well-being for people.

Air is essential for life
Air conditioning and ventilation systems ensure high indoor air quality, which has a positive effect on health, well-being, the ability to concentrate and productivity.
Top Themes ISH Water
In addition to design aspects, 2023 the ISH Water section is focusing particularly on the topic of sustainability. Whether in the consideration of materiality, production or long-lasting concepts for bathroom design for all generations and needs - the theme of sustainability hovers over everything. Of particular interest here is sustainable installation and quality for the valuable resource of water, as well as energy efficiency in the (hot) water supply.
Sustainable Bathroom

Bathroom renovation – plenty of comfort for every room
More and more building owners are paying attention to sustainability when renovating their bathrooms. In addition to a long service life, the use of resource-saving products and technologies is playing an increasingly important role.

Resource Water

Safe drinking-water installations – concepts for hygiene stations in buildings open to the public
The pandemic has brought the topic of hygiene into the public focus and shown how important it is in all areas of daily life. Hygiene solutions for buildings will be considered, planned and implemented even more strongly in the future.

Uniform standards of quality in the EU – for sustainable materials and products in drinking water installations
The standards of quality required of materials and products used for drinking-water distribution are regulated nationally. Binding and EU-wide standards of consumer protection and quality are not yet in existence. Nevertheless, the EU Drinking Water Directive, which came into force in 2021, means a single market with harmonised standards of quality is now in sight.

Energy efficiency, easy access or hygiene – how to make an ‘and’ out of an ‘or’
The fundamental prerequisites are: water must flow; cold water must stay cold and hot water must stay hot. Reconciling these aspects with the sustainable use of the energy available to us has been shifting more and more into the focus of attention over many years.
