Improved air quality

MFO park is one of the green infrastructures in the city of Zurich. Instead of designated space between paved streets, MFO-Park uses the structure of an old factory building as its skeleton, taking the form of a multilevel building that seamlessly fits into the surrounding structures. The basis for MFO-Park comes from an old industrial building which used to be a weapons production and testing complex. MFO has received a series of awards, including recognition as the “Most Innovative Contemporary Park or Garden”– a prestigious designation from the European Garden Heritage Network (Ref 1).

The Urban Environment Observatory Building (OMAU) was built in Malaga as part of the URB-AL 1998 project, it is a construction planned for environmental conservation and includes an ecological cover for the use of rain water in the supply to the structure's watering system. (Ref 2, 3)

Baubotanik Tower is a test and demonstration building in Wald-Ruhestetten, approx. 150km south of Stuttgart. It exemplifies new engineering possibilities with living plants and visualizes the architectural and ecological potential of Baubotanik. Baubotanik or Living Plant Constructions is a technology of building with living trees, advanced by Stuttgart architect Ferdinand Ludwig. Baubotanik shapes living tree branches, stems and roots of trees into buildings to use qualities of forest in a dense city. For this purpose, living and non-living structural details are joined in a way they can grow together into a botanical and technical compound structure (ref 1, 2, 5).

On November 5, 2019, the Committee for Urban Development and Technology passed the building decision for the riverside park Austraße - Neckarterrassen. To the north of Münster, the Neckar has cut deeply into the shell limestone and describes a wide arc on the Prallufer. There is little space between the cliff and the river - that is what makes this place so special. This is where the Austraße riverside park is being built with the elements Freienstein water playground (element 1), Neckarterrassen and Tapach-Link (element 2) as well as Austraße, Neckarufer and Neckarstrand (element 3). The first component has already been implemented: children will find their favorite spot on the Freienstein water playground south of the Max-Eyth-Steg. Students from the Elise von König School in Münster contributed their ideas as part of a child participation program. With the second component and its sub-projects “Tapach-Link” and “Neckarterrassen”, there are beautiful prospects for Münster: Those who have overcome the relay to the Neckarterrassen can rest in the shade and let their eyes wander up and down the Neckar. The third component of the Austraße riverside park - in addition to the Freienstein water playground, Neckarterrassen and Tapach-Link - focuses on the banks: podiums and platforms are planned on the river to linger while the freighters transport their goods on the water. Insects, small crabs and small fish find optimal living conditions on the renatured bank zones with stones and diverse flora. (1, 7).

The winners of Smogathon 2016 suggested building a large green wall in the centre of Kraków. Based on the modern technologies the artificially placed wall made of metal and moss would clean local air, lower the temperature, retain water, increase biodiversity and serve as a decoration for the city centre [1,2]. The project was not completed due to lack of scientific data on its effectiveness and the weak price and outcomes balance; the city is still searching for more economical and practical solutions [6].

Four hackberry trees were planted in the courtyard of the social center "La Grande Bastide". Children were involved with the support of the association "Aux Actes Citoyens" (in english"Act Citizens"). The planting of the 4 trees by the children was done with the support of animators/leaders (who work at the Social Center and animate diverse activities at the center), Karine Lurcin, president of the association "Aux Acts Citizens" as well as several members of the association. (Ref. 1). The Social Center of the "Grande Bastide"(non-governmental organization) was behind the idea, stating that: "It is the idea of ​​the center to have the children do the planting. We will surely be inspired by it for future actions", and, "from today, [the children] will always associate the earth with a particular and positive emotion: pleasure" (Ref. 1).

In 2013, St Davids shopping centre, which has over 200 stores and restaurants (ref 5) completed the installation of a green roof, which included bird boxes and beehives and the centre is looking to expand its green roof further. The city shopping centre has become the home of a 60,000-strong colony of bees. A second green roof was developed in 2015 in the parking garage to expand educational programs (ref 4). School children from Cardiff were involved in the planting of seedlings to create pollinator habitats for bees, butterflies and other local wildlife around the ‘Hayes’ area (ref 3). The customers and local community, with the help of this project, have been taught about the value of adopting an eco-friendly approach to public space. (ref 1)

The project involves the BBC Drama Village - a combination of studios and stores with associated offices and technical suites. It was the requirement for all buildings to achieve a BREEAM Excellent standard (ref 1). GreenBlue Urban structural RootCell systems were used for this development to create adequate tree root volumes, to ensure optimum tree establishment and growth in a demanding coastal location (ref 2). A Living Wall has been made which has a number of functions including the provision of a new home for solitary bees, lacewings and other invertebrates. A rainwater harvesting system has been installed (ref 1). Speaking generally, the studio, stores and office amounted to over 18,000 square meters and 900 new meters of HV, gas water drainage and telecoms (ref 1). Areas of eco-design include transportation, energy efficiency, water efficiency, materials, indoor environmental quality, waste reduction and biodiversity (ref 1).

As an open root space, climbing plants usually only need a small floor area. Such planting areas can be cut out in a semicircular shape
directly on the facade, for example in the eaves strip of the roof overhangs (irrigation may be necessary). The city department for urban development initiated a funding programme for green facades and walls on private property in the city district of Wolbeck. It formed part of the proposed measures of the urban redevelopment programme for the district to improve its attractiveness and enhance green spaces. It included the reimbursement of up to 70 per cent of the arising material costs provided that the owner commits to maintaining the green façade for ten years. Although only three parties participated in the programme, public awareness of the multiple benefits of green space were raised (ref. 1, 2, 3 and 4).

The Hetton Lyons Primary School's green roof is designed to evolve and flourish over the coming years, helping to combat a number of climate change issues facing the next generation. Aims were ecological benefits, providing a natural habitat for plants and wildlife while helping to reduce air and noise pollution, cutting carbon emissions and assisting with rainwater retention and attenuation (Ref 1).
