The project LIFE ASTI is developing policies for a better adaptation to Urban Heat Island effect impacts, especially during summer heat waves, reducing the heat wave risk in metropolitan areas by introducing heat prevention services, and better-implementing energy efficiency guidelines in European cities. Thessaloniki and Rome, the two Mediterranean cities will give a representative geographical coverage, to reflect different environmental conditions and to support one of the major EU policy priorities for joint forces and transnational cooperation. The first Technical & Monitoring meeting of the project LIFE ASTI took place in Rome, on March 7th-8th.
