Increase or improve urban vegetation cover to help reduce outdoor temperature

The project relating to the waterfront of San Girolamo di Bari is an important piece of the mosaic that provides a new design for the entire city waterfront, from North to South: Santo Spirito, Palese, (precisely) San Girolamo, the connection between Bread and Tomato and Torre Quetta, temporary uses on the San Giorgio waterfront, up to the redevelopment of the South promenade. The project which is almost completed, regenerated the seaside part of Bari, making the seaside accessible and link the city with the coastal area by creating a multi-functional space where playgrounds, a cycling path and green open spaces were built to enhance the liveability of the area. In this way, what was previously considered just as an economic and working part of the city became a new center of social interaction by creating a new institutional green space. (Ref.1, Ref.6).

Liko-Noe is a business office building that meets all of its energy demands on its own and has a sophisticated system of water reuse and management. The building features a green roof, a green facade, and water storage ponds on the outside (Ref. 1). The building has a constructed treatment wetland for the wastewater treatment, uses solar energy for photovoltaic panels as well as thermal wall (Ref. 4). The aim of the project is to demonstrate that nature-based building techniques can significantly help address the challenges of soil and water degradation, and climate change (Ref. 1).

The municipality initiated to realize a healthy and climate-proof 'city island' which includes a large variety of projects, including the City Island Park Tour, which is a cycling/walking tour around the island that includes multiple green-blue infrastructure elements along two canals. Together it can be recognized as a large city park (ref. 2, 6). The tour contains the sights of green banks, recreation possibilities, bridges and boulevard-ways, thereby promoting environmental quality, mobility and attractiveness of the area (ref. 6). A food park at Leeuwensteyn is envisioned for 2050 (ref. 7).

Skainos is a community regeneration project developed by the Methodist Church in Ireland’s East Belfast Mission. The Skainos Project has created the Vertical Gardens where around 6,500 plants make up the vertical panels, with a height of 12.5 m. The panels are designed to change colour with the seasons and will attract wildlife. The plants condition the air, remove pollutants, and provide seasonal colour and vegetation. A variety of roof gardens harbour natural flora and fauna. Green Roof technology is used to help with water retention. (Ref 2, Ref 6, Ref 7)

The project started in 2013, when a group of private companies started a collaboration with the municipality of Bari to build a series of gardens on the top of households roofs in the city. With a total extension of 2000 sqm for the experiment, the main goal is to create a small micro-climate. The main advantages of this experiment is an improvement in the process of absorption of rain and to reduce energetic costs for heating. The green roofs are expected to play a role in facing the challenges posed by climate change. (Ref.1.)

Trees and a park have been created and designed for the double building project called CEMAGREF/ENGREF in Clermont-Ferrand which was planned in 1994 (Ref. 2 and 4). CEMAGREF (Center for the Study of Agricultural Mechanization of Agricultural Engineering of Water and Forests) and ENGREF (National School of Agricultural Engineering of Water and Forests) are located within the IRSTEA (National Science and Technology Research Institute for Environment and Agriculture) (Ref. 3).

Situated in park Spilberk, the garden features a building with a green roof and a garden with various plots. The building is designed to be carbon neutral and reuses rainwater for toilet flushing and for watering the garden plots. The garden is used for horticultural purposes and environmental education, as well as animal and beekeeping. The complex improves the local micro-climate through cooling and humidification and promotes biodiversity. (Ref. 1; Ref. 2; Ref. 5; Ref. 6)

Platenstrasse in the Ginnheim district of Frankfurt was laid out as a four-lane feeder in the 1960s. It leads through the settlement of the same name, which was formerly the housing area of ​​the US armed forces. After their withdrawal in 1994, the settlement came into municipal ownership. Many large families, often with a migration background, moved in. Wild parking lots and storage spaces were created without any quality of stay. In 2000, discussion about the redesign of the Plattenstrasse started and in 2015 it was completely transformed into a green corridor. The street space was rearranged and the paved areas were reduced to the necessary extent. Sensitive planning and respect for the established structures helped to preserve the character of the district while significantly increasing the green area with recreational facilities. (1)

"The desire to integrate trees in the heart of Nancy constitutes a long-standing commitment. The first Charter for Trees of Nancy was signed in 1996. Plant diversity was strengthened and the protection of trees accentuated, in particular thanks to the requirements of the Local Urban Planning. In 2013, the new version of the Charter will make it possible to engage all the actors of urban policy to increase protection of the tree, to be vital to biodiversity and to the quality of the living environment" (Ref. 1). "New legal, urban, ecological and social issues have emerged. The old charter now requires improvements in the face of certain evolutions. It was decided to renew it. This new document is in line with the previous one and faces the new issues of the trees in the city" (Ref. 1, p 9).

The neighbourhood intervention is designed as an eco-neighbourhood with an abundance of green space and facilities to connect its residents to the outdoors and to each other. (Ref. 2, 13) It is part of the European Union Renaissance project that is associated with Lyon, France and Lombardy region, Italy (Ref. 12). In Zaragoza, this district, situated on the south of the city, provides about 10,000 homes (most of which are social housing). From design to construction, the district was developed with bioclimatic criteria. (Ref. 8, 12)
