The picture shows four people in formal dress standing in a modern, light-flooded building. They are standing on a raised walkway with railings, surrounded by large glass windows. The windows extend along the entire length of the corridor and let in plenty of daylight.on the left of the picture is a woman with long, dark hair wearing a black trouser suit. She has her arms crossed in front of her chest and is looking down as if she is pensive. Next to her is a man in a dark blue suit, who is leaning on the railing with both hands and also looking down. Next to him is a woman with blonde hair in a white blazer and beige trousers. To her right is an older man with white hair and a beard, wearing a dark blue suit and interlocking fingers. The four people are discussing ista's building management system. Below the catwalk are large green plants that lend the room a natural element. On the right of the picture you can see a wall with dark red bricks and several doors. The whole space has a modern and open feel, with lots of natural light and a mix of industrial and natural elements.

Stronger together in sustainable energy management

DeaweB focuses on overview, standardization and intelligent control.

DeaweB streamlines CHP management through standardization, central monitoring, and intelligent reports – for greater visibility, reduced downtime, and optimal convenience.

Standardized maintenance across multiple corporations

Smart selection of maintenance batches

Real-time performance monitoring via ReduQ

Prevention of expensive technical interventions

Quarterly reports with management information

Project overview

DeaweB is an initiative of four housing corporations from the West Brabant region that are joining forces to take a more efficient and professional approach to the management of collective thermal energy storage installations. Daily practice showed that the independent management of these installations is complex and that there was often insufficient insight into performance, comfort and energy consumption. To improve this, DeaweB decided to outsource the ATES management. istaDES is now actively involved in the management and optimization of the installations of three of the participating corporations.

Challenge

The housing corporations within DeaweB were confronted with a variety of maintenance contracts, a lack of insight into technical performance and varying levels of comfort for residents. Signals from regulators, such as the environmental service, also made it clear that control of the ATES systems was needed. The aim was to standardise maintenance, select reliable partners, make performance measurable and provide future-proof advice on the functioning of the wells.

Solution

ista has started reading and analyzing the existing maintenance contracts. In consultation with the housing associations, these contracts have been standardised and clear performance indicators (KPIs) have been established.

Afterwards, istaDES supervised a tendering process to select suitable maintenance parties. For each housing association, it is evaluated whether the current maintenance contract meets the needs of both the organization and the residents. Where necessary, KPIs are adjusted and coordinated with the maintenance parties involved.

An inventory of the existing meters has been carried out for all collective installations. These are then linked to the monitoring tool ReduQ, which clearly shows the performance at system level. This provides insight into yields, deviations and trends – crucial for the structural improvement of the installations.

Result

Thanks to istaDES, the housing corporations within DeaweB have uniform maintenance contracts, reliable maintenance parties and transparent performance via ReduQ. Malfunctions are approached proactively, management is scalable and communication with regulators is substantiated and professional. In addition, the reporting structure contributes to cost savings, better comfort and making sustainable decisions.

Success factors

istaDES provides extensive quarterly reports to the housing corporations within DeaweB, providing insight into technical performance, comfort measurements, failure analyses and the achievement of established KPIs for each location. These reports form the basis for targeted control and help to efficiently match the heat supply to the heat demand. A concrete example of the added value is visible with a thermal energy storage source with a cold surplus. Where the environmental service insisted on a technical intervention, istaDES was able to demonstrate with a well-substantiated plan of action that the surplus would fall below the standard within a few years. This prevented a costly and possibly unnecessary intervention. The combination of monitoring, analysis and clear reporting enables the corporations to manage efficiently and make well-considered choices for their energy supply.

"The collaboration with istaDES not only gives us real-time insight into the functioning of our installations, but also helps us to structurally reduce malfunctions and improve comfort for residents. By cleverly linking technology, maintenance and finances, we can manage in a more targeted way and invest in future-proof energy management."
