Purpose – The article aims to describe the approach adopted within the framework of a multi-destination development project, the goal of which is to promote innovative technologies and methods to evaluate the environmental quality of an urban district under construction. Design/methodology/approach – The approach lies in the integration of methodologies usually applied on an urban scale (microclimate well-being and air quality, study of air quality), and/or to the individual building (acoustic comfort evaluation), never before adopted for assessment of plots or districts, especially in the dynamic evaluation of the variables identified, all objectively measurable. This method of analysis has been tested on an area of about 255,000 m2, located in the former historic district of the Fiera di Milano, where a series of typical urban functions (residential, commercial and trade) are inserted within a large public park. Findings – The success of the work is represented by indicators (air quality, acoustic performance and microclimate) that relate to the finished district and that can be compared with average values in the same city. The system may constitute a protocol capable of bringing benefits to local authorities. Research limitations/implications – The limit is the need of data that support the dynamic simulation (external factors as vehicular traffic, general neighbourhood activity, pollutant emissions) corresponding to the different seasons. These data are not always available by the municipalities. Practical implications – This type of assessment could be requested of developers/builders for complex projects, resulting in changes to the initial plan if the assessment identifies critical issues related to the design choices (orientation of buildings, quality and presence of green areas, traffic emissions inside the urban district, etc.), with the ultimate goal of creating neighbourhoods with better environmental conditions. Originality/value – The research produces solutions addressed to the Italian situation, but it identifies systems and methods used in other countries.

Metropolitan cities can play a primary role in the creation of more resilient urban environments, by developing public interventions that improve social cohesion, and economic and environmental sustainability. The metropolitan city of Milan has emerged among the first European cities that successfully overcame the economic crisis without losing their leadership role. Thus, we analyzed the Milanese experience as an example of urban resilience, in the context of a Research Project of Relevant National Interest (PRIN) entitled “Metropolitan Cities: Economic-territorial strategies, financial constraints, and circular regeneration”. In a first stage, we studied the investments of the major real estate players who have directed their attention to Milan. Our scrutiny showed that most of the investments concentrate in recent urban renewal programs, which entail the re-location of corporate headquarters. A conspicuous portion of commercial real estate hosts fashion companies, as Milan attracts many brands from all over the world. In a second stage, we investigated in more detail the property settlement dynamics that drive corporate real estate development and re-location in the territory of Milan. This showed some urban clusters that the service and fashion sectors are respectively interested in. Finally, we looked into the re-location strategies of eight leader companies, half of which in the fashion sector and half in the general services. Through interviews with their real estate managers, we scrutinized their choice of location in Milan, their environmental sustainability requirements, and added value that they expect to obtain. The fashion sector resulted as particularly keen on rehabilitating divested sites or abandoned buildings, inherited from previous industrial/productive activities. Our scrutiny demonstrated that regeneration projects, can successfully meet the objectives of companies, while matching the goals of public interventions to improve social cohesion, and economic and environmental sustainability. This evidence can inform investors, organizations, and designers, and support them in the implementation of strategies to improve urban resilience.
