Green + grey: eco-oriented redevelopment of urban contexts

Urban regeneration aims to pursue an upgraded level of sustainability each time with a new experience creating a positive competition between nations, trying to differentiate their works with innovative technologies. The purpose is to develop areas to create sustainable, multi-functional, totally accessible public spaces characterized by two components: the green component (vegetation) and the grey one (built environment), which will become the main elements to achieve a new eco-oriented reticular redevelopment. The case study of Hudson Yards set an example of how sustainable technologies can be used to create a mixed-use real estate with office, residential and retail space, integrated with a central green public square. The new structure of urban context is itself becoming a new platform for sharing: the collection of data through IT tools such as GIS (Geographic Information System) allows to keep every aspect under control and to make it understandable to everyone.
