Digitalisation for more resource efficiency

From efficient light sources and renewable energy to self-learning systems, there is no silver bullet when it comes to going carbon neutral. Making properties more climate-friendly requires action on multiple fronts. Deka Immobilien is teaming up with its partners to tackle the issue of climate protection.

One example of how focusing on many details means more sustainability is our retail park in Göttingen. A LoRaWAN has been set up at the Kauf Park retail park to read all meters and sensors digitally. The Stadtwerke Göttingen dashboard not only displays current energy consumption, it also enables monitoring and response to peaks in consumption. That makes it possible to manage the centre’s operation with a greater eye to resource efficiency.

Sustainability means working on a lot of details. In Göttingen, we worked together with local partners and succeeded in significantly reducing the building’s energy and CO2 footprint using smart technology.

Intelligent energy efficiency

With over 60 shops and a sales area of around 45,000 sqm, the Kauf Park retail park in Göttingen has been part of the Deka Immobilien portfolio since 8 February 2019. Together with the centre management provider Völkel and Stadtwerke Göttingen, a dedicated Long Range Wide Area Network (LoRaWAN) was set up for the shopping centre, and all meters and sensors were equipped with a corresponding interface. LoRaWAN is an energy-saving (low power) network that collects data over long distances (wide area) using smart radio devices to enable convenient evaluation.

For this purpose, the total area of the centre, which spans approximately 160,000 sqm, was equipped with various electronic sensors in a complex process. The sensors generate data via two gateways installed on the premises.

Currently, all 150 consumption meters for electricity, heat, gas and water are radio transmitted to a dashboard. Measured values on energy consumption, for example, can be controlled and monitored cost-effectively to optimise resources. In addition, emergency sensors have been integrated to detect faults in the supply network and deviations from the standard values for CO2, humidity, temperature, indoor sound levels and underground car parks at an early stage.

Naturally, Kauf Park has almost completely converted its lighting concept to energy-saving LED technology. From ceiling, shop window and effect lighting to emergency lighting and security lighting, 90% of all light sources in the interior and exterior area have already been replaced.

The cheapest and most climate-friendly kilowatt-hour is the one you don’t consume. Kauf Park uses a modern lighting concept with LED technology and motion detectors. All of the green electricity it purchases is generated by hydroelectric power.

Implementing the UN Sustainable Development Goals

The use of LoRaWAN technology at the site enables all performance data to be automatically recorded and transferred to a system aimed at constantly improving the operation of the building.
