The campus of NCSR Demokritos, hosting ahedd, is located at the bounds of Agia Paraskevi city, 10 km from Athens city centre and on the hillside of Hymettus mountain. The facilities cover approximately 61 hectares, with 3.5 hectares of buildings spread in a woodland setting. In this campus, more than 1,000 researchers, engineers, technicians and administrative personnel work in offices, laboratories or in the maintenance of the campus, and thousands of visitors are admitted every year for school visits, conferences and business meetings among others. The European Investment Bank is currently co-funding the renovation of the campus setting the grounds for the deployment of smart capabilities. This environment acts apparently as a small-scale city-like infrastructure and is ideal for the simulation and testing of innovative smart city applications.
