Vertical Forests

  Vertical Forest

Vertical forest  is a model for sustainable residential building, a  project for metropolitan reforestation contributing to the regeneration of the environment and urban biodiversity without the implication of expanding the city upon the territory. It is a model of vertical densification of nature within the city that operates in relation to policies for reforestation and naturalization of large urban and metropolitan borders.

Benefits of Vertical Forests :-

·        Biological Habitats

·        Mitigations

·        Anti-sprawls

Biological Habitats:-

Vertical  Forests increases biodiversity. It helps to set up an urban ecosystem where a different kind of vegetation creates a vertical environment which can also be colonized by birds and insects , and therefore becomes both a magnet for and a symbol of spontaneous re-colonization of the city by vegetation and by animal life. The creation of a number of vertical forests in the city can set up a network of environmental corridors which will give life to the main parks in the city, bringing together the green space of avenues and gardens and interweaving various spaces of spontaneous vegetation growth

Mitigations:-

Vertical forest helps to build a micro-climate and to filter dust particles which are present in the urban environment. The diversity of the plants helps to create humidity and absorbs CO2 and dust ,produces oxygen, protects people and houses from harmful sun rays and from acoustic pollution.

Anti-sprawl:-

Vertical forest is an anti-sprawl measure which aims to control and reduce urban expansion . If we think in the terms of urban densification, each tower o the Vertical forest is equivalent to an area of urban sprawl of family houses and buildings o up to 50,000 square meters.

Key elements to look for:-

·        Trees:- Trees are a key element. The types of trees are made to fit their positioning on the facades and by height, and plants used in this type project should be pre cultivated. Over a period these plants can slowly get used to the conditions they will find on the building.

·        Management:- The management of the tree pots is under building regulation, as well as the upkeep of the greenery and the number of plants for each pot

·        Irrigation:- Irrigation in order to understand the need for water , the plan for these buildings took into account the distribution of plants across the various floors and their positioning.

The first example of vertical forest consisting of two residential towers of 110  and 76 m height, was realized in the centre of Milan, on the edge of the Isola neighborhood, hosting 900 trees(each measuring 3,6 or 9 meters) and over 20,000 plants from wide range of shrubs and floral plants distributed according to the sun exposure of the façade. On flat land, each vertical forest equals to 7,000 sq.m of forest. In terms of urban densification it is the equivalent of an area of a single family dwelling of nearly 75,000 sq.m.
