The Newton and Arkwright roof, buildings of the Nottingham Trent University campus, holds one of the region’s largest sedum roofs, which spans its way 2,500m² across the building, creating a home for 13 varieties of sedum, insects, songbirds and a new colony of honey bees, creating a trio of hives over all campuses (ref. 1). A 150m2 bank surrounding the building is unmown in order to promote biodiversity and attract pollinating insects in the summer months. Green-walled gates was also part of the implementation activities of this project. (ref. 5).

The Toulouse based project Green My City is a community collective focused on promoting sustainable consumption and creating a sustainable environment, (Ref. 2) It anticipates constructing thousands of square meters of organic vegetable gardens on the roofs of the city of Toulouse, saving 50 tons of CO2 emissions per year. The project defines itself as a prospective tool, which intervenes in the stream of gardening initiatives: it maps, selects, and then accompanies the initiatives (Ref. 1). The project supports the realisation of environmental initiatives by engaging citizens, communities, businesses and designers to help create an urban oasis (Ref. 23).

In June 2012, the Vertical Plants at the Strasbourg National Institute of Applied Sciences (INSA) were installed by two second-year students. They along with faculty and students undertook a technical and regulatory feasibility study, before taking steps to mobilise local companies to meet the costs of the project (Ref. 1). The advantage is not only aesthetic, but the wall has thermal and acoustic properties, and serves as a refuge for biodiversity and is even capable of absorbing atmospheric pollution (Ref. 2).

In 2016 the Environmental Protection Division of Hannover's Department of Environment and Urban Environment started a common pilot project, KlimaWohL, with Bothfelder Kamp GmbH & Co. KG and the Gundlach Group. The building project in Hanover-Bothfeld, formerly called “Hilligenwöhren”, was renamed to “Herzkamp”. By 2021, the family company Gundlach will build approx. 300 terraced houses, rental and freehold apartments. The aim of the project is to implement a new residential area where the researchers of KlimaWohL can systematically test the climate adaptation strategy of Hanover. The new residential area that aims to be an innovative example of climate-adaption for other cities will be equipped with extensive green surfaces and will pay attention to protect the natural environment and species. (Reference 1, 3). In 2018, planting the edge of the forest was started, wherein a tiered 20m wide border consisting of shrubs and trees were planted between the forest and the residential area. Construction of the rental apartments was started and by 2019, the row houses and semi-detached houses have started to be sold. The shell has been completed and the interior work has started. By 2022, overall completion of the project is foreseen.

Andromeda is the first eco-district of Toulouse Métropole. Extended on the municipalities of Blagnac and Beauzelle, it brings together 210 hectares of green spaces, housing estates, residences and corporate offices. The district has been designed around the principles of sustainable development and the preservation of the environment (Ref. 1). The district includes a green corridor network, rainwater management systems (sumps, gutters, recovery tanks, landscaped basins, etc.), 12,000 trees, and the majority of buildings are equipped with green roofs, while green and blue spaces total 70ha and natural areas are 1/3 of the total area (Ref. 2, 3).

The vertical garden is 600 m2 and is an intervention implemented in Pericon Plaza in the old city of Malaga. The garden is placed above a large metal mural with inspirational words for visitors to contemplate. The garden and metal mural were built on the wall-remains of a former house that stood in the spot but was in disrepair. (Ref 1)

The "New Nature" also called "La Calanque" is a new housing residency and business designed by the famous architect Jean Nouvel. The building design is inspired by the typical Mediterranean sea landscape called "calanque" (creek in english). "As an essential component of the project, vegetation is ubiquitous from the ground to the façades, from the heart of the buildings to the terraced roofs" (Ref. 2).

The Leeds RERF (Recycling and Energy Recovery facility) is the flagship development at the heart of Leeds Integrated Waste Strategy over the next 25 years. Amidst the timber frame on the buildings southern face there's a green ‘living’ wall creating a visually stunning feature in stark contrast to the building’s industrial use. The feature connects to a green roof and softens the building’s visual impact and provide vital bio-diversity to the site and surrounding industrial area. (1, 6)

Vine Court is a student residential complex located at the heart of the University’s city campus. It is equipped with both green and brown roofs, providing environmentally friendly habitats for local flora and fauna, utilizing local plant mixes and building material rubble from the excavated site. (Reference 2). It is at the forefront of sustainable residential development in the UK higher education sector and it was built to a high standard of sustainable design and energy performance. In addition to the eco-technologies incorporated into the structure, the brickwork includes built-in nest boxes for swifts and bats. It has been awarded a design stage BREEAM Excellent certification (Reference 1).

The data centre for Citi Bank in Frankfurt is the first in the world to put sustainability at its heart, setting radical new standards in an industry at the forefront of the fight against global carbon emissions (1). The functional and aesthetic aspects, as well as their CO2 balance and later reusability, played a decisive role in the selection of all materials. Disguising the full volume of the data hall, the iconic green wall features indigenous plants and is fully irrigated by harvested rainwater. The wall, measuring some 55 m by 12 m high, complements the extensive green roof and helps maintain a constant building temperature throughout the year while reducing thermal gain in the summer months.
