As part of the Fifth Dimension research program of the University of Helsinki that examines green roofs from the perspectives of biodiversity and the three dimensions of sustainable development (ecological, social and economical sustainability), 8 green roofs were installed in Helsinki. The aim was to find economically viable solutions that are applicable to Helsinki’s and Finland’s conditions. The project experimented with green roofs in different parts of the country, over half of which are in Helsinki (ref. 1, 2, 3).

The civil society association "Permaculture vorm Eichholz" has made it their agenda to turn a since 2016 abandoned farmhouse into an experience-based, educational, co-design space around the concept of permaculture which is an ecologically inspired design concept for creating resilient and durable agricultural areas while maintaining the diversity of cultural and natural habitats. The farm, which was established in 2017, promotes alternative cultivation methods and energy concepts via seminars and workshops and constitutes an experimental lab for interested citizens who can implement their own ideas or even take over responsibility for parts of the farm they develop and cultivate themselves (Ref. 1, 2, 3). The leaders of the project also plan to implement a sustainable energy concept, with the goal of making the farm self-sufficient in it’s energy consumption by producing renewable energies in a variety of ways.

An enterprise called Alicante Forestal constructed a vertical garden in Mallorca, in an office in Santa Ponca (Ref 1). The garden was installed indoors, making a green wall in the headquarters of the local business (Ref 1). There is in 2020 not only this garden, but a service given by Alicante Forestal in Mallorca to design and install these in other parts of Spain, as well as courses for building these gardens in different countries in the world including Spain, Colombia, Ecuador, Argentina and Mexico (Ref 3).

This project deals with the creation of a green roof and a green area around the new headquarters of the IDOM Group (an independent multinational company that offers professional integrated services in Consulting, Engineering and Architecture around the world), located in an old French warehouse (a customs warehouse) on the Deusto canal in the port of Bilbao. It has an area of ​​14,400 m2 dedicated to offices, research and development spaces such as white room and workshop prototypes, and social spaces. (Ref 1)

Parque Central da Asprela is being designed by a team of specialists who see the great challenge of hydrographic control of Ribeira da Asprela and all other surrounding streams as an opportunity to create a unique landscape space in Porto, pleasant not only for the enjoyment of population but also as a crossing solution (pedestrian or cycling) for the academic community that daily studies and works in this area of ​​the city. The park is part of the green lung of the city. This NBS is a continuation of an action implemented in 2015 by the Municipality of Porto that had in mind the creation of a park which eventually had to be renovated and integrated and this is how this new NBS came to be implemented.

The landscaping of the Vuosaari landfill site has appeared to be an excellent example of ”Integrated Planning Approach” as following concepts were applied: restorative design; ecological design; regenerative development and conventional design (ref. 1). The unused Vuosaari landfill hill had been transformed into a natural area where now domestic plants grow in meadows and rocky conditions. The area is now also used for recreational, educational and scientific purposes (ref 1, 2). The purpose of the project was to promote social, economic and environmental activities at the Vuosaari landfill site (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).

The project of regeneration of Nürnberg's main market square and the resulting increase in attractiveness of the area is a result of negotiations between local authorities, citizens and landscape architects. It aims at increasing greenery in the city centre and its overall environmental and aesthetic conditions (1).
The status of the project is unclear, the project might have been cancelled as there is no indication of any interventions taking place.

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].
