Create or improve outdoor spaces to help people escape from urban heat

Number One First Street is at the corner of Medlock Street and Whitworth Street behind the train arches near Oxford Road Station in the city center of Manchester (ref. 6). During the redevelopment of the former BT building now called Number One First Street a green roof was installed (ref 2). Whilst the vegetation slowly established, it provided a habitat for invertebrates and insects. A green wall, accommodating 37,000 plants was planned to be installed by 2020 which would replace glass, plastic and metal cladding with greenery (ref 1).

As part of the restoration of park Denis Gardens, an innovative water element was built consisting of water flowing down the stairs, circulated and cleaned by a pump and filters. This helps regulate the local microclimate by reducing temperatures in hot days and creating humidity in the air (Ref. 1; Ref. 5). Also, the element allows people to walk bare-footed and cool off. In addition, the water reduces air pollution by extracting dust from the air, and the structure has an aesthetic and recreational function, with a restaurant underneath. (Ref. 1; Ref. 2; Ref. 6).

The project involved the revitalization of the area in Cacovická island in order to create conditions for year-round recreation and relaxation in the natural environment and to restore the ecosystem in the floodplain of the river Svitavy (Ref. 3). The project also restored the cultural heritage of the area by integrating elements of Celtic heritage within the design, as well as environmental education (Ref. 4).

The Leeds Parks and Green Space Strategy is a park protection, improvement, and creation program in Leeds under their Cultural Strategy. Main priorities are set out to achieve a vision where good quality and accessible parks and green spaces are at the heart of the community and meet the needs of everyone who lives, works, visits or invests in Leeds, now and for the future (Ref 5). The Parks and Green Space Strategy looks at the contribution made to priorities nationally and locally, and how it fits within the Leeds Cultural Strategy to develop parks and green spaces (Ref 3). Consultation is being undertaken to develop a vision for the future of Leeds City Council owned and managed public parks and green spaces beyond 2020, and a strategy for how to deliver that vision over the next 10 years. The new strategy will replace the previous strategy which runs to 2020 (Ref 9).

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).

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.)

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)

"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)

An urban park located in front of the central train station in Bucharest, built in 1937, and rehabilitated in 2008, as a response to an environmental awareness campaign. The park is a buffer green zone between the train station and the industrial neighborhood (1)
