The steepest multi-apartment ecohouse in the world

One of the most noteworthy realizedProjects ekodah is in Turin. The multi-apartment house impresses with its facades. In fact, they are not limited to the only thing: the "green" technologies are used here as completely as possible. The author of this wonder-house, who made a lot of noise in the West, is the Italian architect Luciano Pia, who has long been working on the idea of ​​integrating nature into a familiar and boring city landscape. His brainchild he called 25 Verde (25 Green), and the greenery in this - and on this - building, indeed, more than enough. Enthusiastic critics note that the architect managed to realize his childhood dream - to build a house on the tree. And who among us in my childhood did not dream about it? Many even built. But never "the house on a tree" has ever incarnated on such a scale in reality. And it's not so much in the large number of trees that were transferred to the facades of the building in their adult form - such projects already exist, and not in a single copy. Everything is much more serious - eco-house 25 Verde absorbed several "green" engineering technologies, and not just "cosmetic" kind. Therefore, it can be considered really a reference ecohouse, one of the best in its class. Reference at the modern level of urban green building.

Ecohouse: trees and shrubs

About "cosmetic" ecology 25 Verde: On the facades live trees and shrubs, neatly transplanted in the adult state in special, large volume metal "pots-kadushki." They were filled not only with earth, but with special nutrition, specially designed soil. This was necessary in order that, in conditions of a limited volume of earthen coma, large trees could develop fully, in spite of the obvious difficulty for root growth. For the third year now, trees and shrubs grow at a normal natural speed and look great. Hence, the landscape designers of the Lineverdi studio Stefania Naretto and Chiara Otella, both doctors of agricultural sciences, have proved their professionalism. The selection of tree species was focused on local species with a powerful friable root system of surface occurrence. Experts chose the deciduous trees - their seasonal variability allows the building not to overheat under the summer sun and, on the contrary, to receive additional solar heat and light from late autumn and early spring. A total of 200 large trees with a height of 2.5 to 8 meters were used. Directly on the building itself - facades and roofs - there are 150 of them. The rest - in the own yard of the U-shaped house with short "legs" and a long facade on Via Chiabrera, 25. Now in Turin at this address, which is well known to all taxi drivers, there is another attraction.

Ecodome: design features

Before the architect Luciano Pia was a complexThe task is to provide a powerful and reliable basis for a very heavy "body" of the building with hundreds of tons of soil in tubs and the living trees themselves. From the idea to execute the consoles integrated into the construction of the building, they refused at once - this, firstly, the project would become more expensive and, secondly, would reduce the living space. It was decided otherwise - to surround the building with a power frame, which will take on all the load. Therefore, the "transport infrastructure" was placed on the terraces, on which the tubs with plants are installed. As power support elements, stylized branching tree trunks are powerful box-shaped welded structures. In the course of construction, they were insured by temporary forests of powerful channel beams, most of which were later dismantled. Naturally, it was not possible to completely hide the power frame, and this task was not put. The work was performed by De-Ga SpA, previously collaborating with Luciano Pia in the implementation of his project Via Calandra building, Via Cavour building, Giardini Vitali-Spina 3 (Giardini Vitali- Spina 3). The immediate curator and developer of technical solutions (construction project) was the engineer Gianni Vercelli (Gianni Vercelli).

Ecodom: green technologies

In addition to the actual trees and shrubs, abundantDecorating the facades, the courtyard and roof of the building 25 Verde, and other solutions related to the so-called "green technologies" are applied. What made him one of the most in the world. The simplest one is a completely atypical lining of a house made of larch scaffolding, according to the type of tile covering. First, it is absolutely natural material. Secondly, larch does not rot at all. Thirdly, together with the litter and sub-base, this decorative facade turns the house into a thermos, which does not radiate heat and does not allow the passage of cold. The effect is all the more powerful because the building itself is constructed of materials with extremely low thermal conductivity. It follows that the costs of residents for air conditioning and heating are sharply reduced. In addition, the "engineer" of the house is built on the principle of the heat pump, which makes the house almost autonomous for heating, water heating and partly for electricity. The heat pump is a high-tech complex that can use the scattered energy and operates on the difference in temperatures of the outside air and underground horizons. And one more important detail: no drop of water falling on the house, is not wasted and does not go to the storm sewer. Intercepted water goes to watering plants and replenishing ponds, for flushing the toilet. All of the above and led to the fact that the brainchild of the architect Luciano Pia was a real "bomb" both from the point of view of the actual architectural, and because of the mass and scale. 25 Verde serves as one of the examples of the concept of greening mass urban housing construction, implemented not as an experiment, but as an "ordinary" residential building of a large city. And did not write about this house - even before putting it into operation - only lazy. By the way, construction began in 2007, and the first tenants moved into their apartments in 2012. It is unlikely that the architect expected that this project will glorify his name - and deservedly - the whole world.

Ecodom as an inhabited object

25 Verde is located in a rather expensive areaTurin, and from the very beginning there was a rush for 63 apartments-apartments. We do not have photographs of the interiors of the living spaces, they are formed by the owners individually, but the total area of ​​the premises of the ecohouse is 7,500 square meters, plus its own park areas on the roof, with. In the courtyard, except for 50 trees, as already mentioned above, shrubs are planted and there are small ponds that add charm and humidity to hot summer days. In this green yard, protected from the street by the house and trees, it is always quiet, here its own microclimate. Still: according to the calculation of landscape design studio Lineverdi, the green decoration of the house produces about 150 thousand liters of oxygen per hour and absorbs 200 thousand liters of carbon dioxide at the same time. How much dust and noise detain the crowns and foliage - can not be accounted for.,
