In the picture, a high stone wall can be seen in the background. The stones are quite small and have been arranged four times, two next to each other and two below each other, in such a way that they have formed several ovals. In front of this wall in the centre of the picture is a small tree in a dark pot. To the left of the tree are two men in dark suits talking about istas heat-contracting. The jacket of the man on the left is open, revealing his white T-shirt, and he is holding a document in his hands in front of his upper body. The man on the right, standing with his back to the plant, is carrying a black cloth bag in his left hand.

With our advanced digital-based products and services, we help to make buildings climate-friendly, safe and comfortable. We provide a comprehensive package of energy management services, based on a wide range of high-quality metering equipment and the most convenient way for data readout. We offer the entire process as a one-stop solution. Our range of products and services covers the supply, installation and commissioning of meters accompanied by detailed consumption-dependent billing of energy, water and ancillary costs.

Energy Efficiency

The fair distribution of energy costs and individual billing motivate residents to save energy - up to 25% according to the European Commission. The fair distribution of energy costs and individual billing motivate residents to save energy - up to 25% according to the European Commission.

The picture shows a man sitting on a balcony in an urban environment. He is wearing a dark blue suit and a white shirt and is sitting relaxed at a small black table on the lower half in the centre of the picture. On the table in front of him are a laptop, a notepad with a pen and a coffee mug. The man has rested his legs on the balcony railing and is holding a telephone in his left hand while talking on the phone. The balcony is richly decorated with plants. On the left of the picture, climbing plants stretch up the wall, taking up almost the entire left side of the picture. Below the climbing plants are several pots of flowering plants and greenery arranged along the floor of the balcony. Above the man, stretched across the balcony, is a string of lights with several light bulbs that extends from the top left-hand corner to the right-hand side of the picture. In the background you can see a row of multi-storey buildings in various shades of yellow stretching across the top and centre of the picture. Behind the buildings is a park-like landscape with many trees that further break up the background. The sun seems to be either rising or setting, giving the picture a warm, golden glow. The view from the balcony extends over the roofs of the city.

Detect & Protect

We ensure a safe and secure living environment: Our digital-based smoke alarm devices help to save lives and make residents feel more safe and comfortable at home. Our drinking water analysis offers protection against potential risks in drinking water and leakages.

The picture shows a green, wide and tall meadow with large green trees on the edge of the horizon in the upper third of the picture and a girl running through the meadow. From the upper edge in the centre, bright yellow rays of sunlight stretch across the middle of the picture and bathe it in warm light. In the centre of the picture, a little girl in a knee-length, sleeveless white dress is walking across the meadow with her back to the viewer. Her long blonde hair blows away from her body to the left as she moves. In addition, as she runs, her left arm is loosely behind her back and her left foot is bent upwards so that the entire underside of her foot can be seen at the end of her dress.

Eco-Friendly properties

Reduce your carbon footprint, build a sustainable future, and enhance your property's image. Our SmartTech solutions offer innovative ways to manage your environmental impact effectively.

Research and development

As the innovation driver of our industry, we invest over 100 million euros in our digital devices and infrastructure every year. Today, we already have more than 25 million connected devices in use. Heat and hot water consumption can therefore be read directly by radio without a meter reader having to enter the apartment. More services for the intelligent multi-family building ("smart building") will be added in future.

Self-made is simply better

Climate protection is a major task that affects everyone. At ista, we have made it our mission to create transparency about energy consumption around the globe. To make it easier for as many people as possible to save energy, CO2 and costs. To achieve this, energy and water consumption must be precisely measured, accurately billed and easy to manage. Property managers and owners need not only first-class services, but also the right technology, such as radio-based heat cost allocators, water and heat meters, and smoke alarms. We develop these devices ourselves - in the ista technical center.

International competence in the middle of the metropolian region Ruhr

To meet the high demands on our technology, you need a motivated, creative team with fresh ideas and professional know-how. That's why we decided in 2017 to bundle all the expertise required for research and equipment development in one place and set up such a team. The ista Technikum was thus created in the middle of the Ruhr region. The location in Essen offers optimal technical conditions, good accessibility and a reliable infrastructure. Around 75 employees from all over the world work here every day to make devices more efficient, data measurements more accurate and climate protection simpler.

Where visions become reality

What drives the future of real estate technology? At our company, new technologies and trends are not just empty buzzwords, but are openly discussed and quickly tested. Nevertheless, innovation is not an end in itself, because the needs of our customers come first. We want to create products that really prove themselves in everyday use. To do this, we constantly retest our devices, expose them to extreme temperatures or humidity, and examine them in the smallest cross-sections. With our in-house 3D printer, good ideas can be realized and tested overnight.

Development of new products

Continuous product tests

Testing of new technologies

Tomorrow's real estate connects residents, managers and other stakeholders digitally. Megatrends such as digitization and topics such as smart homes and the Internet of Things are bringing about technical and social changes that are making our time one of the most interesting in human history, while at the same time constantly placing new demands on data protection and security. Our engineers work every day to create the best solutions for this.
