The inexorable extension of urbanization is consuming huge amounts of soil drastically reducing natural vegetation, replacing it with buildings and low albedo surfaces. The changes due to the different thermal properties of surface materials and the lack of evapotranspiration in urban areas lead to a phenomenon known as "urban heat island effect". By reintroducing the vegetation back into the urban landscape, a partnership between nature and cities should be strengthened to create a new sustainable urban environment. Since the outer surfaces of building offer a great amount of space for vegetation, planting on roofs and walls has become one of the most innovative way to provide several environmental services. Moreover, all the green infrastructures, such as urban gardens or nature areas, that form an important part of cityscapes, could ensure also a thermal isolation and constitute a sustainable energy saving solution for buildings. This work presents a critical review of environmental and potential thermal benefits of green infrastructures in the cities.

Tourism is a sector that accounts for about 10% of European GDP and represents a powerful engine of local development and employment in the European Territory. Europe is the main tourist destination in the world, with 671 million international arrivals in 2017 and Italy is the fourth country in Europe for accommodation facilities. To guarantee "sustainable" accommodation facilities, it is necessary to invest in innovation and technologies that enable energy savings. To support investments in terms of improving the energy efficiency of accommodation facilities, the sector can use the incentive and tax relief system, such as: thermal account, restructuring bonus, eco bonus for energy efficiency, the Tax credit for redevelopment.
