Design of the energy networks in a sustainable district

The paper presents the activity that will be carried out in a district of the city of Torino, Italy, inside the Integrated Project POLYCITY, approved in the Sixth Framework Programme — Priority 6.1 — Sustainable Energy Systems. The POLYCITY project features sustainable energy concepts for very large urban development areas and thus strongly contributes to reducing primary energy consumption and CO2 emissions. The special efforts to integrate building energy demand reduction and renewable energy supply sources using polygeneration technologies is a main requirement of the CONCERTO initiative. The overall project involves several partners from various European Countries, and its main applications will be developed and installed in Spain, Germany and Italy. The POLYCITY project will start in 2005 and will have a duration of five years. The project focuses on large scale urban developments, where living and working areas are integrated to result in sustainable city districts with short distances and low energy consumption. The overall project deals with different aspects of urban conversion, such as new constructions on sites with little development at the city edges of Barcelona (Spain), conversion of an old city district in Torino and a mixture of rehabilitation and new construction on a large military ground near Stuttgart (Germany). The project is integrated in a regional sustainable development strategy.
