THE PROJECT: Porta San Lazzaro Shopping Center - Piacenza

Opened in April 2011, the Porta San Lazzaro Shopping Center is located in Piacenza on the Via Emilia Parmense: the glass-lined structure houses a shopping mall with specialized activities, neighborhood stores, catering areas, game room and parking lots. Orion Italia has designed and commissioned the plant engineering, adopting a KNX-based building automation system based on ABB components.

The number of light circuits controlled by bus is high and covers a wide variety of types of lighting sources. The versatility of the system allows you to get the right scenario both in the performance of calendar activities, and in the case of special events. The automatic management is based on the weather station that detects the position of the sun and the intensity of the light that comes from it. The optimization of the ignitions is also regulated by time slots. Air conditioning is also programmed according to the activities. In addition, the KNX controls the switching on and off of the service area lights and activates the antifreeze protection circuits. The system also controls the opening of the windows in the event of wind or rain, the switching on of all the lights in the event of an intrusion, the status of the main switches and those of the service circuits.

The total reduction in energy consumption compared to a traditional solution was calculated in the order of 14%. In total, there is more than 36,000 kWh saved per year, equal to 26.71 TOE / year and lower CO2 emissions for 62 tons / year. The pay-back of the investment is just under two years.
