Since its extensive expansion, the PlusCity has been one of the most modern shopping centres in Europe. The control system relies on the latest technology from the Austrian software manufacturer NETxAutomation. Due to the good experiences that were made with the software in Lentia City, the decision also fell in favour of the Austrian software supplier even this time.
"We are now playing in the Champions League of European shopping centres!" With these words, PlusCity CEO Ernst Kirchmayr clearly positions himself at the top of the domestic shopping centres. With a sales area of 70,000 m2 and 220 stores, the in 1989 opened PlusCity, is Austria´s third largest shopping centre today. Due to the outstanding success of the past years, a total of 140 million EURO was invested in the expansion of the PlusCity and the Hollywood Megaplex (cinema) as well as in its own streetcar terminal, a 4-lane road connection and a new parking garage.
Intelligent lighting control creates comfort oases for visitors
PlusCity and Hollywood Megaplex were equipped with the latest technology from NETxAutomation. The central lighting control is carried out with the NETx BMS Server, which according to the manufacturer is specialized in the integration of different technologies. The KNX bus forms the basis, and the server can also be used to integrate DALI and DMX into one single project. This allows predefined, inter-system lighting scenes as well as daylight-dependent switching between hot and cold white ("tuneable white"). This colour change, in spite of the artificial light, creates well-being oases by imitating daylight and thus meeting the natural needs of visitors.
Integration of the parking guidance system to optimize energy costs
The NETx BMS Server also provides the corresponding lighting at the parking deck by the integration of DALI and DMX. In addition, the server provides an interface to the existing building management system of the parking deck, which allows optimal operation with appropriate chronicles. An interface to the new management system of the parking deck ensures the right lighting for the individual parking areas. If the number of occupied parking spaces exceeds a defined threshold value, the lighting is intensified or reduced and thus contributes to the optimization of the energy costs.
Flexible lighting by signals from the cash desk and building management systems
In the Hollywood Megaplex, the NETx BMS server combines information from KNX, DALI and DMX with the cash desk and building management systems. Depending on the signals from the cash desk system or the available brightness sensors, the server provides a flexible control of the lighting. Each cinema can be individually controlled as well as general areas. Time-based control is also possible. "The main advantage lies in the person-independent control, so that the same parameters are created in each case regardless of whether the function is called automatically or manually. This is indispensable especially in complicated lighting processes, "says planner Peter Hross.
Cost reduction thanks to energy monitoring
In the PlusCity as well as in the Megaplex, the NETx MaRS Module provides a minute-accurate query of the energy consumption of KNX sub-meters for electricity, cooling, heating and water. This not only facilitates the recording of the operating costs, but also makes it possible to use the data automatically for further processing. In the long term, energy monitoring (daily, monthly, yearly comparison) leads to substantial cost reductions.
