Bogota, the capital of the, has the largest plant wall in the world. It was designed to overcome the lack of green spaces in the city. According to the World Health Organization, four times as much green space is needed to guarantee the well-being of the city’s inhabitants. Mexico City is installing “green walls” along some highway sections to clean up the city.
Vegetal facades, a new trend
Vegetation is always a good ally and even more so when we have to deal with the effects of pollution in the form of poor air quality and climate change in general on a daily basis. The green façade is first of all used largely for its aesthetic side. To vegetate the entire exterior wall of a building facade is to ensure that the vegetal aspect of the building will be far removed from the image of a concrete cube, an active and disturbing construction.
The way of life in cities is often not very ecological and in the end, the lungs of the metropolis, which are shaped like parks, are not enough to fight pollution. For this reason, green facades become small oases within cities.
A construction system based on a green or vegetal facade, or certain constructive details with this material profile, helps and helps the city a lot in multiple aspects such as pollution or acoustic contamination. The Construction of green wall systems. A vegetal wall must be adapted to its environment. Factors such as climate, orientation towards the sun, your preferences and application indoors or outdoors play an important role. That is why Sempergreen offers you tailor-made solutions with the SemperGreenwall system constructions, a green wall. Below we present the most frequently used system constructions for an interior and exterior green wall. A green facade requires regular maintenance to ensure that it develops properly. Terraflore intervenes on site once or twice a year.
If we think about sustainability, these spaces can offer many advantages without using a large surface. Moreover, they are areas that in most cases would not be useful otherwise. And suddenly the facade becomes green! A custom-made creation developed in co-creation for an architect’s project. The creation of a building with an architectural party of vegetal inspiration gave birth to this unique aspect. The reliefs take turns harmoniously from slab to slab. A lively aesthetic for original facades. Substrate: The composition of the vegetalized facades: The vegetal wall is also known as a vegetalized wall, vegetal facade, living wall, vegetal partition or wall garden. A vegetal facade is simply the vegetalization of a vertical section of a building (a wall or a facade) with the help of various plants whose roots are either plunged into the ground or in a tub. The plants will then grow vertically and cover the wall. More precisely, it is a matter of placing a layer of soil on a wall to allow the plants to grow. There are different methods of growing plants vertically. Namely: not all plants will be able to grow on a plant wall because they are not all adapted to grow vertically. They will have to be chosen carefully. Depending on the region and the surrounding climate, Virginia creeper, ivy, wisteria, golden hops, hydrangea and climbing roses decorate facades in the countryside as well as in the city. For centuries, the installation of these climbing plants on facades has contributed to the aesthetics of the building as well as to its thermal comfort.
It is a worldwide trend and some cities even finance the plant cover. This is the case of the Colombian city of Medellín, where the Secretariat of the Environment intends to fill public spaces with these landscapes.
There are two types of structures: vegetal facades and living walls. The first are characterized by the fact that they have supports to channel the growth of plants so that they obtain a vertical position. They generally grow from the ground and the roots are supported by the vertical surface.
Green walls, on the other hand, are structures that are attached to the wall so that the vegetables in the artificial frame can grow. Plants, flowers, algae and even vegetables can be part of these structures through intelligent designs.
In addition, this type of investment can bring more benefits than we think, not only to the environment but also to our own homes. Green walls are able to insulate against outside noise and generate more stable temperatures in both summer and winter.
