The commissioning of the concrete core activation system was to be digitally monitored on the basis of data in order to transfer the building to optimal system operation. Energy savings based on this and a reduction in CO2 emissions should be made possible downstream in continuous operation.
Thanks to the simple plug-and-play connection, the building was quickly brought into regulated system operation despite complex system technology. Savings have been identified on the basis of the data collected since the system was connected. In the future, autonomous, predictive control will be implemented for permanent optimization.
27 859 € annual operating cost savings (1,60 €/m²/a)
254 MWh annual energy savings (14,56 kWh/m²/a)
97 t CO2 annual avoided emissions (5,55 kg /m²/a)
With a clear objective in mind, the optimization of the I/D Cologne A2 started in March 2022. Four phases were decisive in the course of the project before the cloud platform was taken over into continuous optimization operation.
1. Data acquisition by simple plug-and-play installation of an Edge Device.
2. Analysis of the plant components to accompany commissioning
3. Guarantee of correct plant operation
4. Realization of energy savings
Supported by the comprehensive basis of operating data, the facility management team was able to track the concrete core activation and thus optimally accompany the commissioning. The AI-based analysis of the plant components continuously provided valuable insights and facilitated the subsequent documentation and evaluation. After a successful commissioning of the plants, the focus was on the fine-granular correction of the plant operation. Immediate savings were realized through various small adjustments, such as optimizing the running times of the air handling units.
Since using the aedifion cloud platform, energy has been continuously saved in the I/D Cologne A2 through optimized operation. In this way, the operating team simultaneously reduces operating costs and lowers the CO2 emissions of the building. Despite state-of-the-art equipment, savings can thus be achieved and the operator team‘s workload reduced. A win-win-win result for owners, operators and tenants.
Permanent optimization and predictive control - Future-proof system operation is the focus for the modern building, so that predictive switching between heating and cooling becomes possible completely autonomously.
The I/D Cologne A2 is a beacon in terms of digitization and efficiency. We are particularly proud of this project, because with aedifion we have a strong digital tool and an experienced team as a sparring partner for the challenges of such a complex building operation.
