Green roofs and green and living walls are increasingly seen in cities, because they are an important strategy that addresses some key urban environmental issues and allows the achievement of different benefits. Among these, the most relevant ones are reduction of the “Urban Heat Island” effect, of rainfall contributions to the sewer system, of environmental impact and energy saving, and retention of harmful substance. The study aims to analyze different systems of greenery systems integrated (GSI), green roofs (GR), and green and living walls (GW-LW), as a possible retrofit technique of the envelope of heritage buildings and especially their applications in the context of historic cities in Italy, pointing out positive and negative aspects. Particularly, it pays attention to the green retrofitting of buildings and to the technical problems related to the installation of systems, since at the moment there are already several studies that show the environmental and microclimatic benefits of the integration of vegetation in architecture. This study tries to highlight the series of design procedures necessary both in the preliminary phase and then in the executive phase to relate the GSI to the existing building envelopes. The GR, from the results of the simulations conducted, demonstrate a greater simplicity in their construction, with improvements also from the point of view of the working loads on the existing structures, since the interventions are performed more easily than those on the facade. The study highlights the architectural needs that are not always considered such as the increase in the thickness of the roof and the related need to raise its edges, changing the perspective of the building. On the other hand, the GW and the LW show some complexity in their construction because they must deal with facades often rich in decorative elements and where openings affect the assemblage and connection works such as the tinsmiths of the intrados of the openings. It must be taken into consideration the necessity of having to drill masonry, often inhomogeneous, to connect fixings and the problems of stability this entails must be carefully analyzed.

Research has shown the environmental benefits of green envelopes, as well as performance in terms of energy efficiency. To date, there is no analysis of the economic sustainability of these systems, which has allowed the realization of a few, albeit very well known, examples. The research has identified a green modular system integrated into the building envelope, designed to facilitate installation and maintenance, with competitive performance compared to other existing solutions; a system that wants to improve performance and flexibility of vertical applications, experimented on buildings, on the market, and able to adapt, above all, to the needs of the building process. It is important to distinguish architectural aesthetic requirements from those of the building process; the former aim to have an authentic vertical garden, with different kinds of plants where nature dictates the rules, the latter aims to achieve the economic sustainability of vertical greenery systems. This paper provides an analysis of a technique based on the installation of plant bearing modular panels with turf on substructures also provided with a micro-irrigation system, which allows the construction of a modular coating, characterized by reduced thickness, that can also be integrated with other materials; installation is quick and simple, since the panel comes perfectly planted on site. In addition to that it allows, from a botanical point of view, resorting to types of grass selected with a view to climate, exposure, environmental adaptability, color and shape. A comparative analysis of this green façade is also presented compared to other existing case studies, from a constructive and managerial point of view, highlighting both its economic and architectural advantages.

The introduction of vegetation in urban areas, through both green roofs and green walls, is a sustainable strategy for improving the environment and the quality of life, as well as crucial for urban biodiversity since the moment it is able to create new habitats for plant and animal species. The design and realization of green roof systems abroad is promoted and stimulated while in Italy, this subject, is still an innovation not supported by many real implementations. The application of this technological green system has a great importance for the redevelopment of existing building heritage, especially for historic buildings, to improve their energy-performance qualities, with respect for their architectural value. The aim of this study is to identify the technical issues for the realization of green roofs in urbanized contexts by focusing on the implementation of a green roof on a building of Leghorn following intervention guidelines developed. This research shows that not only does this system allow higher energy saving, but it also brings a decrease of load bearing on the structure.

This experimental study on the renewal of post-World War II suburban areas addresses the theme of the technological retrofitting of buildings, focusing on typological features, construction techniques and, more in general, of all aspects that fail to meet the needs of contemporary living. An initial examination of Italian and international case studies helped to identify possible guidelines for the optimization of urban renewal activities. The guidelines were tested by applying them to a case study: a 1950s-era neighborhood in the city of Pisa. The study undertaken highlights the need to consistently integrate all of the activities that affect the building structures-consolidations and static adjustments, improvement of energy efficiency, functional and spatial adaptation-and that work towards strengthening social integration by taking into account the specific needs of the individual. The work is implemented on individual buildings and urban areas, with the aim of improving the local identity characteristics. The suggested approach is that of a circular economy, which helps to reduce the impact on the environment, mainly through the extensive use of recycled materials. The proposed experiment thus aims to test the resilience of buildings following their seismic, energy and functional updating, including sociological and environmental psychology assessments, with particular attention to vulnerable users, in order to find solutions capable of promoting social inclusion.

There is an ever increasing interest in identifying the links between architecture and public health and in how urban design can positively influence the latter. The psychology of sustainability and sustainable development represents an innovative research area as a recent contribution to sustainability science and its trans-disciplinary configuration. The research topic deals with the importance and the centrality of the user-centered approach in the observation of the relationships among mankind, technological systems, and built environments, for projects that guarantee the conditions of physical, mental, and social well-being. Starting from the plurality of different disciplinary sectors, from anthropometry and sociology to psychology, “human experience” and user’s expectations are explored, understood, and systematized. The analysis of the relationship between health and urban design has allowed researchers to identify design strategies to improve the level of urban livability. The city of Pisa is the case study; mobility within the city is redefined through various levels of the use of space so that paths and areas of inclusion and socialization are re-valued, while new scenarios for some urban spaces open up. In this perspective, the design strategies synthetically follow two main directions: the re-appropriation of these places by the citizens and, at the same time, the promotion of their well-being from both a physical and psychological point of view.

One of the main objectives of contemporary society and international research is to improve the physical and psychological health and well-being of the population, especially within the urban space. An effective approach to address this complex issue must necessarily be trans-disciplinary, and must be framed in the broader perspective of the Science of Sustainability, in particular the Psychology of Sustainability and Sustainable Development, as a frame of reference. The study shows the first results of research, in terms of methodology and qualitative analysis, with the following objectives—identification of the criteria for intervention for a healthy city design, with particular attention to the psychological, architectural, and construction aspects, and an initial verification of these criteria, through a case study consisting of a section of the city’s waterfront, in the city of Livorno. This case study has enabled, both, the definition of an innovative design and implementation of solutions, for the correct use, accessibility, and management of spaces. It provides the first evaluation of a possible digital analyses of a waterfront, before and after intervention; and highlights the potential and the critical aspects of the process of recovery and re-appropriation of an urban space, for a new social life, within it.
