Best tall building for 2015

The best tall building for 2015 is a piece of Italian architecture. To be more precise, a skyscraper located in Milan.

The Council on Tall Buildings and Urban Habitat (CTBUH) announced Boeri Studio's Il Bosco Verticale (Vertical Forest’) as the best tall building worldwide at their annual awards, after a long selection between 123 entries representing a total of 33 countries.  

Vertical Forest was applauded for its “extraordinary implementation of vegetation at such scale and height", defined by the Jury as "groundbreaking".

Porta Nuova district - a fast growing residential and commercial hub in Milan, an urban area with a high population density. How to preserve greenery and sustainability with the request for a tower that could house a large population?

The solution: developing green on a vertical dimension. This is the innovation of Bosco Verticale, with its two towers - 80 and 112 metres high - home to more than 900 trees, and a total area of 40.000 square metres.

Green in this project becomes part of the architecture, not just a décor element as it has been for previous works. Indeed, traditional claddings have been replaced by the screens of greenery, transforming a traditional façade into a living one. Green screens carry out the same functions as architectural claddings, as well as bringing their own unique benefits: the greenery preserves a temperate climate by protecting from the summer heat and from the winter wind, it blocks noise pollution and it's a living source of oxygen which absorbs CO2 and fine dusts, which could otherwise be harmful for the resident’s health. 

Green in Bosco Verticale brings comfort to people living inside the skyscraper, but it is also a benefit for the whole area, helping to depollute the city and to rebuild an ecosystem that otherwise would have disappeared in such a busy urban space.

It's really fascinating to explore how plants and green have been carefully studied and chosen for Bosco Verticale. These two buildings host the equivalent of a hectare of forest, divided in to 480 trees of big and medium size, 250 small trees, 5000 shrubs and 11.000 floral plants.

The choice of types of green played a key role in the project, with two years of study by a botanist group that chose the right species according to their size and characteristics, and to fit their positions in the building façade. In their selection experts chose evergreen plants, climbing plants and aromatic plants that could that best adapt to climates on different altitudes and that would not provoke allergies to humans.

Green naturally changes its look during the different seasons, with different natural colours that will make these two building look different from time to time: a living façade!
