ista promotes energy efficiency in buildings worldwide. To achieve this, we are increasingly using digital technologies for the transparent metering, billing, visualisation and management of individual heat consumption – in short, submetering. For one thing is clear: people must become more aware of energy consumption in their own four walls if government climate protection targets are to be achieved.
People can only consciously save energy if they know what they are actually consuming. We create this transparency. Submetering enables every resident of a multi-family building to receive an individual bill for heating and hot water costs. Everyone therefore only pays for the energy they actually consume. And everyone can decide how actively they want to manage their own energy consumption. It has been demonstrated that on average residents make sustainable energy savings of 20% and therefore also cut costs if they receive annual consumption information.
Our customers are housing companies, house owners and home owners’ associations. We are also increasingly extending our activities to include commercial properties.
Changing customer needs and requirements encourage us to systematically develop our infrastructure further. We therefore already read energy consumption using modern radio technology in over 60% of all the properties we look after today. And we are aiming for 75% next year. After all, submetering works even better when it is digital. Radio technology has two major advantages for the consumer: firstly, there is no need for a meter-reading appointment and, secondly, consumption figures and costs can be processed and viewed even more transparently on a web portal or smartphone – not just once a year but also regularly during the heating period. As the latest studies show, residents who receive visualised monthly data consume on average another 7% to 12% less energy than residents who are not given this information.
The greater transparency provided by individual consumption figures can therefore lead to greater energy savings. However, real control possibilities and influence on user behaviour in multi-family buildings are currently available to only the very few. The buzzwords here are « smart home » and « smart building ». In the multi-family building sector, there have so far been very few approaches which live up to this claim. We are therefore continuously developing our core competence, submetering, towards the smart, energy-efficient multi-family building. This year, in cooperation with Dr. Riedel Automatisierungstechnik, we launched an initial product for the intelligent control of heating and other appliances in multi-family buildings.
We are thinking further ahead in this direction and are already planning more intelligent bundled offerings geared to energy efficiency, convenience and safety. Today, we already offer services for greater tenant safety throughout Germany, for example smoke alarm devices and drinking water analyses, which we will also develop further in future.
