Achieved impacts

As part of the EU Life+ CITYWATER project (of 3 cities), a sustainable stormwater management solution based on biofiltration was implemented in Maunulanpuisto Park in Helsinki, in order to purify rainwater and meltwater and improve water quality in the Haaganpuro Brook.
As the drainage area is heavily trafficked and paved with asphalt, high solid, nutrient and oil levels have occasionally been measured in the rainwater and meltwater entering the Haaganpuro brook. Such contamination is harmful to the fish stocks (e.g. trout) and other organisms in the brook. The biofiltration solution was the first of its kind in Helsinki. The solution also supported the City of Helsinki stormwater strategy, which aims at changing management towards sustainable solutions and states that stormwater should in first hand be infiltrated on spot, where it is created (ref. 1).

The experimental green facade system consisting of four different types of green wall was installed in Nurnberg from 2013 until 2016 on Adolf-Braun-Strasse 33 and is an integrated greening system that enables self-sufficient, low-maintenance "hanging gardens" on facades and other vertical walls. The aim of the project is to experiment with recreating green spaces in the streets, asphalt surfaces, and backyards of some parts of Nuremberg overcoming numerous constraints and competing uses (1) The implementation has helped improve air quality, thermal insulation, wind and rain protection and lowering local temperatures in its proximity.

The Veneto Eye Bank Foundation, a social welfare organization and regional centre of reference for cornea transplantation and research into epithelial stem cells, is a distinct and iconic project which embraces architect Emilio Ambasz's philosophy of "The Green Over the Gray," or the landscape over the building. It is a triangular-shaped building with a series of landscaped terraces at each floor level on one side. On the opposite side, the building rises as a series of steps that lead to a flat planted roof garden turning it into an outdoor amphitheatre. The combination of the plantings and deep overhangs minimises the impact of heat loads by blocking sunlight during the middle of the day (ref 1).

Weaver Park is was built on an area of 0.6 ha in the Liberties area in Dublin. It is one of the developments that form a part of the Liberties Greening Strategy. The park’s purpose was to address the lack of green space in the area, to provide a place for skateboarding and other recreational activities, and a place for relaxation and community events.

After relevant local regulations had been adapted and allowed for keeping apiaries in the city of Białystok, in 2016, the Institute of Biology at the University of Bialystok put six beehives on its rooftop. The initiative aims at increasing biodiversity and pollination in the city. It promotes beekeeping and sustainable production and consumption patterns, and the honey is a brand product of the University [1,3,4].

The Reconstruction of the Southern Bank of Schütt Island is the starting point of the regeneration of the Old City of Nurnberg. Within the project, the access to water and recreational functions of the river banks were improved. (1) The project was completed on an 1800 square meter large area, which includes open meadow areas, a 170-meter-long bank terrace, trees, and benches. (6) Public participation through co-planning and consultation was also involved in the planning process. (1)

The Podlasie Opera and Philharmonic – European Art Centre in Białystok ("green opera") in Białystok, is known for its green roofs, green walls and extensive gardens, which perfectly harmonize with the surroundings. The green area serves as a platform for cultural events and successfully promotes the city. Opera gardens are divided into several levels with lawns, walking paths, bridges, sculptures, and small ponds. Different green elements of the building reduce heat effect and noise, increase the thermal insulation of the building, improve local biodiversity and limit rain drainage to the city centre [1].

In 2014, students, instructors and representatives of an appropriate company built a "small green roof" on the balcony above the entrance to the Department of Architecture at the Bialystok University of Technology. The initiative was a part of the "Green City by nature" project - a nationwide educational campaign about nature-based urban solutions. It took only 5 hours to unfold the roll of grass and prepare the ground for all year thuja and vines [1,2].

Weaver Square Community Garden started in May 2011 on a derelict site owned by Dublin City Council. The site contains the Community Garden and 28 individual allotments let out by the council. The main focus of the Community Garden is to create a safe and relaxing green space for all to use and enjoy. The organizers hope in the future to have more emphasis on the garden as a learning experience, with open days & workshops and other related talks. Dublin City Council has given notice that Weaver Square Community Garden and 27 family allotments are to close at the end of 2018. (Ref. 1; Ref. 2; Ref. 3)

As part of a larger project, this project aimed at creating a vertical garden in the Levante Square, in the Deustro neighborhood, the city of Bilbao. The intervention was initiated by the Bilbao's municipality in 2016 and aimed at creating a green area that was a bit unconventional and artistic at the same time. The landscape design incorporates local elements such as the trawlers, the cliffs of the Cantabrian coast and the local architecture, integrating nature and tradition (Ref 1).
