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.
