Future-proof and compliant

From complex to simple and reliable.

Organisations often face major challenges in managing and maintaining the performance of collective or sustainable energy systems. These challenges stem from a lack of internal technical, financial or administrative capacity, the increasing complexity of energy infrastructure and regulations, and the constant need to strike a balance between efficiency and satisfaction. Without specialised expertise, systems can become inefficient, expensive and unreliable, leading to financial risks and frequent complaints.

Professional management via istaDES combines all crucial tasks in one comprehensive service. From technical and financial management to contract management, advance payments, billing, customer contact and smart consumption monitoring. This integrated approach increases performance, reduces costs, extends the life of the system and increases transparency. For managers of commercial and industrial property, this means greater efficiency and certainty in compliance, while users benefit from convenience and reliable service.

How does istaDES work?

istaDES works with an independent heating company for the B2C model. For the B2B model via an ESCO, ista works with reputable partners. This gives you flexibility in your choice to bill your users' heat consumption according to tenancy law or the Heat Act. The heat tariffs are determined annually in consultation with you, the heating company and ista. This gives users the certainty that they will not pay too much and gives you the opportunity to invest in sustainability measures.
 

The services we provide to commercial and industrial property managers take the hassle out of operating sustainable heating systems. This allows you to focus on your core business, namely letting properties. The combination of our services and our collaboration with the heating company sets us apart from other heating companies. Our expertise lies in providing technical and financial services related to heating installations and the correct distribution of operating costs between property managers and users.

Laying the foundations.

istaDES' services have been developed based on the wishes and needs of the market. Installations are becoming more complex, measuring systems smarter, and data collection and climate measures increasingly important. This leads to higher quality requirements and broader expectations from customers. istaDES supports you in all aspects of heat exploitation with specialist knowledge. From technical management and financial returns to customer service and legal aspects of collective energy installations.

Professional management of your (sustainable) energy installations.

The technical management of your (sustainable) energy installation is in good hands with istaDES.

In addition, we formulate a long-term perspective on maintaining the energy installation. Your installer handles complaints and malfunctions, with istaDES continuously looking over their shoulder. The technical manager at istaDES is a fully-fledged discussion partner for the installer. The technical efficiency is also periodically mapped out and discussed with the client. Advice is also given on improving the technical performance of the energy installation.

Three phases for the launch of istaDES.

Start-up management of the collective installation.

Before management of the communal installation can commence, istaDES determines its status by means of a readout. The (communal) installation must meet a number of criteria before management can be taken over.  After completion of the readout phase, you will receive a readout report for each location.

Clean up – repair.

The defects or shortcomings identified during the import process must be rectified. The supervision or implementation of this clean-up process is carried out under the direction of istaDES.

Managing the energy installation.

After completion of phases 1 and 2, the management phase begins. During the management phase, it becomes clear whether the energy installation is financially and technically profitable. If the return on investment is insufficient, istaDES advises on possible improvements to the energy installation in order to increase returns.

The picture shows a smiling man holding a tablet on which ista's Energy Management Minute View is displayed. The man has brown hair and is wearing black glasses. He is wearing a beige and grey striped shirt and a blue blazer over it. He is standing in the centre of the picture and looking directly into the camera. A modern office can be seen in the background. On the left-hand side of the picture is a wooden shelf in front of a black wall, decorated with long hanging plants and various objects that give the impression of awards. On the right of the picture, two women are sitting next to each other at a white work table covered with various work items. The woman in front, whose long black hair and beige loose top are visible, rests her arms on the table and has turned her head towards her colleague, so that only the back of her head is visible. The woman next to her has long blonde hair and is wearing a light blue shirt. Her side profile is recognisable. The entire background is blurred so that the focus is on the smiling man with the tablet.
