Figure 6: User of Interact Office Case Study Amsterdam Schiphol Airport, The Netherlands The Amsterdam Schiphol Airport is one of the busiest airports in the world. Open 24 hours a day, seven days a week, the single terminal airport consists of three halls, each connected by several piers and concourses. It is the third busiest airport in Europe in terms of passenger volume, and the world’s 11 th busiest by total passenger traffic. In 2016, over 63 million passengers passed through the airport. In 2015, Schiphol Group, Cofely, and Signify entered into collaboration for the new lighting at the terminal buildings at Schiphol Airport. This meant that Signify would be the owner of all light fixtures and installations while Cofely would maintain a round-the-clock presence at Schiphol Airport to service the lighting. Schiphol Airport would pay a monthly service fee for guaranteed lighting. The move by Schiphol Airport to rent lighting from Signify is in line with Amsterdam’s 2015 Sustainability Agenda, which proposed adopting a circular economy to reduce wastage and increase energy savings through investment in energy efficient products. By applying circular economy principles, Schiphol Group, Cofely, and Signify have created a new standard in Europe in the transition towards sustainable lighting. The result: the 9,000m 2 terminal building saw over 3,700 new lighting fixtures and installations. The airport’s energy-efficient LED lamps enjoyed a 50% reduction in electricity consumption compared to conventional lighting systems. The specially designed lighting fixtures for Schiphol Airport also last 75% longer than conventional fixtures because of their improved serviceability and consequently, lifetimes. Since fixture components can also be individually replaced, this reduces maintenance costs and lowers raw material consumption. Today, millions of holiday and business travellers continue to transit through Schiphol Airport, enjoying the security and comfort of sustainable lighting in a welcoming environment. Signify Circular Lighting ensures Schiphol Airport does not need to worry about lighting maintenance and care, allowing them to fully turn their focus to their travellers. 21
