A case-study of green roof monitoring. The building of Council for Agricultural Research and Economics in Bagheria (PA), (Italy).

The energy saving in building goes on as an important challenge in the policy of Developed Countries. While the issue of energy building efficiency in heating season has deeply been investigated for a long time, the issue of energy building efficiency in cooling season is relatively recent. Moreover, considering the increase of electric consumption for air-conditioning in summer, mainly due to the growing quality of life, the research of technologies for reducing energy building consumption during this season becomes essential. The green roof represents a technology useful to reduce the energy consumption during the cooling season. In this work the authors report the results of a monitoring campaign of temperature through a green roof that is installed in a building situ in a town close to Palermo, South of Italy.
