Measurements of biophysical aspects of the NBS (e.g. temperature, water flow)

The 16-storey EnBW Administrative Complex and planned office district in Stuttgart's industrial area of Fasanenhof has three wings and a high-rise for about 2,000 employees on the 35,000 square meter sites, with many extensive green roofs and usable intensive roofs over underground parking. With the new office complex, EnBW wanted to create a modern and pioneering work environment for its employees. Different green system solutions were used on the project including a "Natural Roof", "Garden Roof", "Public Roof" and "Landscape Roof", with both extensive as well as walk-intensive plantings. The resulting green roofs offer respite and recreation for employees and visitors. [ref 1, 2]

The Gorla Maggiore water park, inaugurated in March 2013, is situated within the municipality of Gorla Maggiore, in the Italian region Lombardy, located about 30 kilometers northwest of Milan. The water park is a constructed wetlands (CW) built on the banks of the Olona river that includes (a) a pollutant removal area composed of a grid, a sedimentation tank and four vertical sub-surface flow constructed wetlands; (b) a multipurpose area with a surface flow constructed wetland or pond with multiple roles; and (c) a recreational park with restored riparian trees, green open space, walking and cycling paths.

The John Muir Pollinator Way is an initiative by the NGO Buglife to create and restore pollinator habitats along a 215 km long-distance active travel route – The John Muir Way – across the densely populated central belt of Scotland. The John Muir Pollinator Way is the first B-Line ‘pathway’ in Scotland and stretches from Helensburgh in the west to Dunbar in the east (Emilie). It is an ambitious project given the length (215 km) of this pathway. It connects nine different local authorities and 40 km of the total length falls within the Edinburgh local authority area (Burgess, 2016). This not only serves to halt the process of declining pollinator numbers providing crucial ecosystem services, but also helps people to connect with nature. Between July 2015 and March 2017, project partners and volunteers have transformed 19 sites into species-rich grassland. [ref 1]

The Stavros Niarchos Foundation Cultural Center (SNFCC) is a project finalised in 2016 and “handed over” through a public/private partnership scheme, from the foundation/donor to the Greek state. The site hosts the National Library of Greece and the Greek National Opera in a 170,000 sq m landscaped park. The SNFCC's objective is to restore Greece's image and become a global role model of environmental sustainability. The project is committed to a range of educational and cultural activities, which have been provided for free. It also claims flood-regulating functions, air quality improvement impacts and shade provision, among others. [1]

The Tree Strategy is a municipal action plan in progress, aiming to address some of the main sustainability challenges described in the Environmental Program of Malmö City. Its main relations to sustainability challenges include improved health and well-being, decrease differences in those among different social groups and increase biodiversity. The Strategy includes a range of possibilities for evaluating its ecological and social success (ref. 1).

The idea of beekeeping originated from AUDI AG, Audi Hungaria's parent company. In 2015, Audi Hungaria was in the midst of implementing its flora and fauna protection plan thus the beekeeping idea was in line with ongoing developments, and was quickly taken up by management. 6 bee colonies with 270,000 bees were installed in September 2015. The bees produce 200-240 kilograms of honey each year, which is branded as Audi Hungaria Premium Honey, and gifted to visitors, as well as purchasable in the gift shop. The income is used for nature conservation programmes. The company also cooperates with the University of Sopron in a biomonitoring project which uses the bees as bioindicators of environmental pollution. (Reference 1)

A project of the local government developed with EU and federal funds that aimed at the development of the green and beach area in the course of the refurbishment of the flood protection system. The initiative sought to provide a model project for urban flood protection, which can showcase that flood protection measures do not require a separation between city and water and new recreational spaces at the water and shore can be created instead. The project involves redevelopment of the shore area, enlargement of the public space at the shore with additional sand deposit and greenery planting (Ref. 1, 2). The bank area with a beach and recreational facilities opened in May 2019 (Ref. 5).

The Belvedere College Urban Farm is run by students from the school and by the Urban Farm start-up. The complex consists of a greenhouse and an open farm, both situated on the rooftop of Belvedere College. The project serves as a testing ground for researching sustainable farming practices, provides education and practical experience on the topic to students, and is part of a collaborative food network in the local area. (ref 1, 7, 8)

The renaturalization of the water canal Hirtenbach project was part of the larger city-wide initiative that aimed at the naturalization of different parts of the city's drainage system including small trenches and streams. The initiative aimed to decrease the risk of floods, improve the water quality, protect the local flora and fauna from the pollution, as well as provide for an additional recreational area for the citizens. (Reference 1)
In 2000, natural remodelling or the creation of near-natural structures began in sections. A 20, 000 m3 retention basin was also built. These actions improved flood protection and ecology of the area, and it provided local recreation opportunities. However, a study conducted in 2014 revealed that the restoration measures brought positive changes, but it was not enough to achieve a “good water status” defined by the European Water Framework Directive. Intensive care from silting and lush plant growth, wide margins, and the reduction of nutrients coming from the drainage and agriculture, need to be addressed. (Reference 2)
A new landscape is expected to be created when the alder trees grow. Waterbirds and waders, as well as insects like dragonflies, bees, butterflies and crickets, have been observed in the area (Reference 3).
The large drainage system of the city of Hannover includes many small trenches and streams with a total length of 152 kilometres. The intervention in Hirtenbach involved renaturalization worked on the total length of approximately 10,5 km (of which 3,3 km in the urban area). (Reference 2)

Hanken School of Economics has placed green walls on its campus in Helsinki. The walls are placed in libraries and group rooms where students spend long periods of time to provide better air quality (ref, 2). The NaturVention (now known as Naava) patented active green walls are claimed to filter air 100 times more effectively than regular indoor plants (ref. 3). With pure and fresh Naava air, it is claimed that people can focus on their day, while Naava takes care of their air (ref. 5).
