Green densification model

The project was born from the purchasing of an ex-military area in the Flaminio neighbourhood and the decision to build a city of science with a museum, a public park and residential areas that will have green roofs and sustainable, energy-efficient building. The project was proposed to several architectural studios and the Studio 015 Paola Viganò is the one who got assigned the project in 2015 (3).
Due to changes in public administration and financing already found in 2017 (7), the project still has not started (2020), as in 2019 the citizens were once again consulted over the works and the project (7). Initially, the project should end in 2023 (should last 8 years) (4).

This vertical garden was created with the aim to integrate the shopping mall in the surrounding green. A total of 44.000 plants of 200 different species were used on a surface of 1.262 square meters, making it the largest living wall in the world (now in Italy) at the time it was created. The green wall has met large positive response both by the owners of the shopping mall, who noticed a decrease in their energy expenses, and by local residents, who can appreciate the aesthetic beauty of the wall and breathe fresher and cleaner air.

The green area which surrounds the famous museum has been renewed in the last years. It is an interesting site of botanic interest, as there are more than 400 species of plants living there, and more than 150.000 trees. In particular, the company Slow Food Campania cultivated a small vegetable garden. Is a project of small- scale agriculture, in order to enhance a variety of cultivation and biodiversity conservation. The company Slow Food has been supported by the company Lande srl, specialized in the revitalization of historical green areas at the urban level (Ref.1).
The interventions include the restoration and re-functionalization of 10 areas: the Garden and Casamento Torre, the Giardino della Fruttiera di basso, the Fagianeria, the Capraia, the Porta di Mezzo, the Cisternone, the Cellaio, the Vallone di San Gennaro, the ex Eremo dei Cappuccini (Ref.1).

The roof of IKEA in Åsane outside Bergen covers 22,000 m2 and has been covered with plants since 2011. (Ref. 1) The green roof promotes biodiversity, cleanses the air from pollutants and acts an important flood prevention measure in the region, as Bergen experiences a lot of rainfall and is expected to receive more as a consequence of climate change over the coming decades. (Ref. 3,5) The roof has attracted a lot of birdlife, including endangered species. (Ref. 2)

The Vertical Garden Wall situated at the J&T Bank Café Bratislava was constructed in 2010 as Bratislava's first vertical green wall. The green wall in the two-story J & T Bank Café is one of the most recent implementations of Patrick Blanc – botanist and the creator of Vertical Garden. The Café was designed by the architectural studio MIMOLIMIT, and has been realized under the supervision of AED project. The vertical garden consists of more than 2600 plants of 66 various species (3).

This office complex at 10 Gedonstrasse in Munich was completed in the spring of 2002 with a pre-grown Ceratodon purpureum green roof and living green wall panels. It uses a special technique called BRYOTEC Technology, which enables the producing of (plant) mosses for revitalization. The biological crusts of mosses which it produces play a very important role in engineered soil media stabilisation, accelerating the development of depleted soils/substrates for vegetation establishment.
The extensive green roof is built up from mosses that require minimum maintenance. (Reference 1, 4)

A modern office building in Poznan and a headquarter of a large company was designed to include multiple environmentally friendly solutions like cycling facilities, energy-efficient appliances in the building, roof gardens, the use of rainwater in the sanitary facilities, waste segregation system and the overall energy-efficient design of the building façade to let in as much natural light as possible [1].

"Tirone Alto Vesuvio" is a park situated within the Vesuvio area in Naples, this area was recently qualified as an eco-campus (green infrastructure), a project realized in 2011 according to the European guidelines for sustainable tourism. In particular, the eco-campus has the goal to promote sustainable and zero-impact sports activities, in order to spread awareness on ecological issues. In addition, it provides important health benefits and social and cultural advantages (Ref.1).

A landscape scheme had laid out around the Scottish Parliament building and structures were turfed and covered in grass. The landscaping softens the concrete canopies with wildflower meadows, rooftop gardens, ponds, plants, flowers etc. 2 distinct types of green roofs are present at the Parliament - wildflower meadow grass canopies and roof gardens. The Parliament is built on a brownfield site and it has increased the biodiversity of the site. A number of rare and native grasses were planted in the parliament’s open spaces. (ref 1)

The Edinburgh Living Landscape (ELL) is a partnership between the Scottish Wildlife Trust, the City of Edinburgh Council, Edinburgh and Lothians Greenspace Trust (EGLT), the Royal Botanic Garden Edinburgh, Green Surge and Edinburgh University, it aims to help make Edinburgh a city fit for the future by fashioning healthy and beautiful environments that are resilient to climate change as well as being highly valued and accessible to people. It is made up of a range of projects that will create, restore and connect green areas of the city to make attractive and biodiverse landscapes that are enjoyed by residents and visitors. One of the examples is the Holyrood park. Naturalisation was tested in Holyrood Park, where a once regularly mown grassland is now cut only once per year. It benefits both wildlife and public amenity and also reduces maintenance costs for the site, with the potential to spend elsewhere on greenspace maintenance. This is a part of the ongoing Edinburgh Living Landscape Case Study which aims to make Edinburgh a city with healthy and beautiful environments, resilient to climate change. A range of similar projects will create, restore and connect green areas of the city to make an attractive and biodiverse landscape (ref 2, 3).
