Reduced noise exposure

The hurricane Kyrill devastated up to one-third of the tree stock in the city of Münster and thereby changed the green cityscape in 2007. Therefore, the civic society movement "Foundation Citizens for Münster" initiated the project "Bürgerbäume" (literal translation: citizen trees) to foster reforestation of the promenade of the city castle and other affected spots in 2008. In collaboration with the city department for urban green, motivated citizens and citizen groups took over tree sponsorships with up to € 1,000 per tree to help restore the urban green within three months after the event (ref. 1, 4).

“The Hub, a new purpose-built student building (at the heart of the Coventry University campus) was designed to enhance the student experience, i.e. offers space to meet up with friends or study informally.” The building also includes a number of green credentials such as: ground source cooling from a borehole on-site; natural ventilation; grey water harvesting (rain water for the toilets); solar water heating and a green roof.” (Ref. 1)

The Petuelpark is an approximately a 7,4-hectare large park in the north of Munich, situated on a section of the Petuelring between Belgradstrasse and Leopoldstrasse and partly over the Petueltunnel. The park was created as part of the complex transportation development project that aimed to reduce above-ground traffic with the help of the tunnel and improving the quality of life in the area with the help of green development. The park was also aimed at creating a space for recreation: several playgrounds, a water playground, a fountain, a café and several artworks can be found there. (Reference 1) The park also includes the “Generation garden” which is designed to serve as a meeting place, and a place for gardening, as garden beds have been laid out in the garden for free use by the residents. (Reference 3) The elevated parts that situate above the tunnel are implemented as extensive grassy areas, while the other parts are dominated by thematic gardens and the Nymphenburg-Biedersteiner canal (Reference 3).

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)

"This disctrict of "Plateau de Haye" is part of the EcoQuartier approach, is one of the most ambitious urban renewal projects. In line with the development of the New Urban Renewal Program, work was carried out this year [2012] on the challenges of opening up territory to its urban and forestry environment in order to confirm the "Forest City" approach initiated by the architect-town planner Alexandre Chemetoff" (Ref. 1). It received the EcoQuartier National Grand Prize (Ref. 2). A forest, community gardens and a green corridor are being developed with a rainwater recovery system (Ref. 2). Work is set to continue until 2024 (Ref. 10). "It will first allow work to be done on the functionalities of the district : development of spaces freed up by the demolition of the Blanc Sycamore and the Purple Beech, reconversion of the Tamaris and Ombelles into housing, shops and spaces dedicated to companies, creation of green spaces , shared gardens and parking" (Ref. 10).

In 2019, the city of Poznań finalized works on another city park, as a part of its long-term urban redevelopment plan. When designing the park, the focus was on creating a place for relaxing and recreation for all residents - regardless of what forms of activity and relaxation they prefer. Therefore, the entire area has been divided into zones adapted to different needs, be it for active adults, children, or dog owners. The park comprises of an extensive lawn and is separated from a noisy street by a corridor of trees. Everything is lit with solar lamps [1,2,5].

To increase the attractiveness of the area around the block of houses, the city of Poznań plans to plant an oak stand of about 50 trees (first and completed phase) and again 50 trees (second ongoing phase) in two designated plots. The planted greenery will serve as a natural noise barrier and offsetting for a concrete block of flats nearby [1,5].

There are various projects under the Den Grønne Kile initiative or the Green Wedge. The Green Wedge passes through all 4 subdivisions of the new district Aarhus K, and has a building percentage of 25% within the boundaries of the "wedge". (Ref. 3) Citizens are invited to contribute with green projects through the municipal innovation project "Green Citizen" (Grøn Medborger). (Ref. 1) The first and most prominent is a park created by citizens on an old railway track. The park has the nickname 'Kilen' and is a new city park for everyone, including upcoming residents and companies in the new district 'Aarhus K'. The park helps to promote the creative energy in the area and is in line with the development of the new district; it differs from the other city parks in Aarhus by offering space for many different activities and temporary projects that give life to 'Kilen' and make the trip along the railway track an exciting experience. (Ref. 1)

In 2012, the City of Lisbon has implemented a 2,5 km green corridor connecting Monsanto Forest Park ( 900ha) and the city centre through Eduardo VII Park. (1) It is a concept of continuous natural structure, consisting of a coordinated set of green spaces that intend to continuously bring the natural space to the interior of the city (ref.3)
This corridor is a fundamental part of the Ecological Structure, a matrix formed and articulated by systems: the Mobility System, the Water and Air Circulation System, the Fluvial-Estuarine Transition System and the Structural Ecological Units System.

Lisbon's Biodiversity Route is a pedestrian route of 14 km, marked according to the norms of the Portuguese Federation of Camping and Mountaineering. It connects the Forest Park of Monsanto to the Tejo river, which aims to contribute to raising the awareness of the value of the city's biodiversity (ref. 4). The position and dimension of these connected areas important in relation to the climate regulation, air quality and for the diversity of habitats that the city offers. The Biodiversity Route is a circular route, which can be done on foot or by bicycle where each species of fauna and flora that can be observed (Ref.1).
