The Sello shopping center in Finland’s second-largest city of Espoo, west of Helsinki, emphasizes in its marketing that the center is about “much more than just shopping.” There are also coffee houses, a library, a concert hall, movie theaters, a bowling alley and other kinds of areas where people come together. This diversity obviously means high demands on monitoring the lighting, heating and ventilation. All systems must be monitored and controlled to meet Sello’s two major goals: energy efficiency and perfect conditions for the 24 million customers that visit the shopping center each year.
This is a huge undertaking – but not impossible. In partnership with Siemens, Sello has been using Navigator, a Siemens cloud-based energy and sustainability platform, to monitor and analyze the center’s ventilation units, room sensors and lighting systems in all the various spaces and shops. According to Olli Paunola, the property manager at Sello, Navigator has given them considerably more options for how they can monitor the building’s operations and better adjust the system and conditions. “It’s crucial in terms of energy savings,” he says, “because it allows us to monitor the workings of the system for long periods of time.” Already for 2017 the center has managed to save 680 MWh in electricity and 800 MWh in district heating and has reduced its energy costs by around €93,000 over an eight-month period when compared to last year.
