Water-bearing systems are of fundamental importance in modern buildings. They are used to transport, store and distribute water efficiently.
Water-bearing systems not only contribute to efficiency, but also to the sustainability of buildings. A central element is the drinking water supply system, which ensures that there is always access to clean and healthy drinking water.
In the heating circuit, water-bearing systems ensure that heat energy is transported efficiently from heating appliances to the various rooms and enable even heat distribution.
By reusing water, resources can be saved and the ecological impact reduced.
Drinking water circuit
Modern drinking water systems in residential and non-residential buildings must be designed to meet strict hygiene requirements. This includes the use of suitable pipework, regular maintenance and the integration of filter and water treatment systems to ensure water quality.
A sustainable water supply in buildings relies on technological innovations and hygienic standards to ensure a closed and reliable cycle.
Digital solutions can also contribute to the efficient use of drinking water. Due to intelligent water management systems it possible to monitor water consumption in real time and support the early identification of leaks. In dry regions, ensuring sustainable access to drinking water requires innovative solutions. This includes efficient water extraction and treatment processes that are adapted to local conditions.
The ISH offers topics and solutions for a hygienic drinking water supply in buildings, including resource-saving and digital solutions for saving water and access to drinking water in dry regions or stricken areas.
Heating circuit
Water as a heat transfer medium circulates via pumps, pipes and valves to the radiators or underfloor heating systems. Thermostats ensure the desired room temperature. In addition to efficient heat transfer and even heat distribution, water-bearing systems allow individual control of the room temperature. They can also be used for different heating purposes and can therefore be flexibly adapted to the specific requirements of a building. Overall, water-bearing systems in the heating circuit offer a comprehensive solution for efficient, comfortable and sustainable room heating in different types of building.
Utilisation of process and rainwater
Water-bearing systems for utilistation of process water and rainwater plays an important role in sustainable water cycles. They enable the efficient utilisation of water resources for buildings. Ecological and economic benefits can be achieved by utilising alternatives such as well water or treated process water.
The use of water in bathrooms, kitchens and other sanitary facilities within buildings is an important area of water utilisation. Water-saving fittings, efficient toilets and conscious use of water can reduce consumption.
Rainwater utilisation is a sustainable method of collecting rainwater and using it for various purposes. Special systems are used to collect rainwater, store it and distribute it as required. These systems usually include gutters, downpipes, filters and water storage tanks. The collected rainwater can then be used for watering gardens, flushing toilets or even for the washing machine, so that the precious drinking water can be reduced.
Green roofs and facades
Green roofs and facades are sustainable design elements that do not only comply with the demands of aesthetic architecture but also offer numerous ecological and economic benefits. The greening of roofs and façades helps to improve the energy efficiency of buildings and increases the quality of life in cities.
Irrigation and drainage systems play a key role in the greening of roofs and facades.
Green roofs are particularly suitable for collecting rainwater and feeding it into a rainwater treatment system via a pipe system. Drainage pipes are characterised by their space-saving dimensions and high drainage capacity with a small pipe diameter.
An irrigation system is required to ensure that green areas on roofs and facades are watered all year round. Drip irrigation systems with drip pipes and hoses or mist systems are among the options available.
Drainage for buildings
A wastewater or drainage system is required to drain entire buildings. The components for a drainage system consist of pipes, fittings and drains. Pipes are mainly made of plastic, galvanised sheet steel or refractory cast iron. For drainage in buildings, the gradient and diameter of the pipes and the arrangement of all pipes must be precisely coordinated.
Connection pipes run between the drains of the individual drainage objects, e.g. kitchen sink, shower, WC, washbasin, and are routed via a downpipe or horizontal pipes. Odour traps also prevent odours from escaping from the sanitary items into the room. Sufficient ventilation of the pipes is also necessary for building drainage.
