For our customers and their tenants, we are solution-providers and partners for greater energy efficiency in buildings. Today, we already offer intelligent products and services that increase energy efficiency, safety and convenience in buildings. With our products and services, we promote the responsible use of energy and natural resources and actively help to shape the energy transition.
Our portfolio focuses on heat meters, water meters and heat cost allocators which record energy and water consumption using digital radio technology and therefore give our customers and their tenants transparent information on their individual consumption behaviour. Our portfolio also covers solutions for greater tenant safety by offering smoke alarm device services and drinking water analyses.
We pursue a clear goal with our range of products and services: our customers are to benefit as much as possible from our low-investment offerings. With its new technical possibilities, digitalisation has opened up an extended world of products to us – products with which we can offer our customers not only greater convenience but also create even greater transparency and therefore lasting incentives to save energy.
We have continually developed our core competence – the metering, billing and visualisation of energy consumption – in the direction of the smart, energy-efficient multi-family building.
Therefore, when designing our portfolio, we focus on developing innovative products. We are guided by the maxim that every euro invested should have not only the greatest possible but also fastest possible beneficial impact for our customers and their tenants. As an energy service provider, we have continually developed our core competence – the metering, billing and visualisation of energy consumption – in the direction of the smart, energy-efficient multi-family building. Our strength is ista’s radio technology, which enables us to digitally read consumption. This has two advantages: firstly, greater convenience for the tenant as no meter-reading appointments are required, and secondly, consumers get an even more accurate insight into their individual energy consumption thanks to this professional database.
In contrast to conventional smart home solutions, we concentrate on the entire building including the individual apartments. With the platform solution, “ista Smart Building“, which was developed in cooperation with Dr. Riedel Automatisierungstechnik GmbH, we are today already setting standards for tomorrow’s home: tenants and residents can considerably reduce the energy consumption of a multi-family building in future. A display in the apartment hall shows the residents detailed information on their individual consumption behaviour and enables them to take action to optimise it. Further radio-based smart home applications can be integrated into the solution, for example for lights, electrical appliances, ventilation systems or roller blinds. The system meets the requirements of the highest energy efficiency class for building automation. According to DIN EN 15232, energy savings of up to 19% can therefore be achieved.
We are extending our portfolio in a targeted manner and so offering a number of products and services which enable us to exploit the possibilities offered by digitalisation to the benefit of man and the environment.

The ista temperature logger provides automatic visualisation of the room temperature. This makes it easier to maintain minimum and maximum temperatures in rooms. As part of the temperature logger service, we also offer to inform property managers if the temperature exceeds or falls below a preset desired room temperature so they can react to any malfunctions, for example of the heating system.
The online portal for tenants and customers shows their sub-annual consumption figures in an easy-to-understand form and therefore combines clarity with incentives to reduce consumption.
With the ista energy app which received an award from Initiative Mittelstand, tenants can use their mobile to keep an eye on their consumption. On the basis of this knowledge, they can cut costs, save valuable resources and reduce CO2 emissions.
ista has developed an intelligent control system that indicates continous leaks caused by dripping water taps or constant flushing toilets. In the event of water abnormalities an alert is send to the property manager [and visualized in the web portal].
To ensure quality and environmental compatibility, we have introduced a quality management system certified to ISO 9001 at the German sites in Gladbeck (logistics warehouse), Au (production facility) and Essen (company head office). In life cycle analyses, we examine the relationship between CO2 emissions produced in connection with our devices and future savings.
Taking our heat cost allocator doprimo 3 radio net as an example, we were able to prove that consumption-dependent heating cost billing saves 158 times more CO2 than is produced during the device’s entire life cycle. The CO2 emissions were calculated over the entire life cycle of the doprimo 3 radio net to produce its carbon footprint. The life cycle is ten years on average and includes the production of raw materials, manufacture, transport, installation, use and disposal or recycling. More on product recycling.
In a model project conducted since 2013 together with the German Energy Agency, the German Tenants’ Association and the Federal Ministry for Environment, Nature Conservation, Building and Nuclear Safety, we have proved that our products and services help to sustainably save energy. As part of the largest field trial in Europe for sub-annual consumption information, “Saving Money through Clever Heating”, we have enabled some 200 households throughout Germany to regularly view their consumption free of charge on our web portal. The result: tenants who receive monthly information on their heat consumption use an average of 16% less energy than tenants who do not receive regular information. In 2015, we won the German CSR Award for our engagement in the “Saving Money through Clever Heating” pilot project. You will find further information on this and other studies here.
