Located in the heart of Hung Phu, a new urban area within Can Tho, K-Villa+ has been designed to "mak[e] the most of open and harmonious space[s] with nature, using green design solutions to improve bioclimatic comfort for users, while respecting sustainable values ​​and being friendly to the living environment" (Ref. 5). The low construction density of the building project has been coupled with prioritisation and installation of green areas both on the building itself and in the surrounding ground; permeable coverings to increase water percolation, and landscaping with native and climate-adapted trees and plants (Refs. 1 & 5.) An ecological pond has further been included in the landscaping of the villa's grounds and a rainwater harvesting system has been installed (Ref. 3). Through the application of these green design solutions, the urban heat island is considered to be reduced and bioclimate improved for those within the building, and biodiversity promoted through the planting of a variety of native species (Refs. 1, 2, 3 & 5).

Note that due to a lack of data, the exact point location of the villa is not depicted in the map below, but rather the new urban district, Hung Phu, in which the villa sits.

The City of Melbourne, through its Urban Forest Strategy, has a comprehensive plan for greening major streets and precincts, but not the smaller laneways. Across the municipality, laneways occupy a ground area of 60 hectares, with a further 150 hectares of space on the walls in these laneways (3). "The City of Melbourne has established the GYL program in 2016 with the vision to help transform the city’s smaller laneways into leafy, green and better usable spaces for the residents and other visitors to enjoy while addressing the city’s sustainability challenges." (1 p27). So far, a pilot project has been carried our including the transformation of 4 laneways: Coromandel Place, Guildford Lane, Meyers Place and Katherine Place (1,3). The intervention included an intensive planning process with the involvement of stakeholders from the private and public sectors and the creation of an interactive map of laneways ideal for greening. (1,2). The GYL program aims to address the issues of urban heat islands, climate change impacts of flood mitigation while also improving local aesthetics, amenity and creating opportunities for recreation (1).

The Urban Forest Fund (UFF) was launched in May 2017 by the City of Melbourne to provide financial support to new greening projects that otherwise would not be able to be funded. Such projects include green spaces, tree planting, vertical greening or green roofs on private land" (1 p20). The City of Melbourne has multiple strategies and programs in place to increase the quantity and quality of green space in the city. The UFF aims to support such sustainability lead initiatives by providing match-funding grants to green projects in the private realm. The UFF is a key initiative in tackling sustainability challenges in the entire city, as 75% of its land is privately owned (1)

The project "Sustainable Support Program for Greening Buildings and Minimizing the use of space using the example of Hanover" was established jointly by BUND (Bund für Umwelt und Naturschutz Deutschland) and the state capital of Hanover. The goal of the project is to transform as many barren house walls and dull grey roofs and asphalted areas into green oases throughout the city. Since May 2013, all house and landowners, housing associations and building communities have been able to apply to the BUND for a subsidy for green roofs and facades. On 2017, the project was expanded to include unsealing of areas like inner courtyards, driveways, etc, thus creating new green areas. Advice on the correct greening measures and on professional unsealing have been also offered by BUND.
The project is funded by the state capital of Hanover, the German Federal Environmental Foundation (DBU), the Sparkasse Hannover and by proKlima. The "Green Hanover" funding program will end on December 31, 2020. (Reference 1)

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).

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.

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).

Instead of expanding the Ring of Antwerp to improve mobility, the municipality of Antwerp decided to use the space to create a Green Ring of 13 kilometers consisting of a wide range of projects (Ref. 3). This large city plan contains green spaces along the Ring, green corridors between those green spaces and with existing parks, a new green park, neighborhood green spaces, restoring the historical city wall and so on (Ref. 3). The plan also contains measures to improve water storing capacity (Ref. 4).

The Faktory project claims to be the first European smart greenhouse, located in the Science Park of Liege. The building serves as a Private Incubator of young start-ups focusing on tech, but it has sustainability goals, too; it is a showcase of urban agriculture, there is biodiversity integration, and the plants produced in the building contribute to supplying the cafeteria (Ref. 1).

"Formerly a 10 hectare market gardening site, the Repainville area is rich in environmental potential: ponds, streams, springs ... the aquatic environment is present everywhere. There is a great variety of fauna and flora. As an ecosystem that is particularly rare in urban areas, protection and recovery measures are being undertaken" (Ref. 1). The restoration of the wetland of Repainville is part of a flagship project of the municipality in terms of safeguarding biodiversity in urban areas. With arrangements allowing the public to walk there without harming the biological and natural diversity of the place, the site has an educational dimension in order in particular to make young audiences aware of the preservation of the ecosystem (Ref. 7).
