(I) Vertical Gardens

12 April, 2013 No Comments

We describe the “ecological urbanism” concept as the trend of eco-construction. Environmental protection and energy management are increasingly a global concern. “Vertical gardens” create green spaces within the cities, covering building’s facades, divisor walls, hotel courtyards and a wide range of possibilities.

There is a difference betgreeenwall iiween traditional green walls and vertical gardens that are self-sufficient:

On one hand, green walls are those covered with climbing plants such as ivy or bougainvillea, whose roots are spread within the ground, from which they get the water and food to grow up. These plants use the wall as a support to grow taking many years to cover it all. Climbing plants may damage the wall or create humidity problems in the building’s foundations, given the thickness of its roots.

On the other hand, vertical gardens can be found inside or outside a building, consisting of a wide variety of species that receive the water and nutrients from the wall, rather than directly from the ground. To prevent moisture from reaching the walls, designers chose to place a galvanized structure as a base leaving a space of 2 to 5 cm between the wall and the centers of plants to create a ventilation channel.

These gardens can complement urban architecture by displaying walls full of color that may vary as the vegetation grows, thus altering the initial greenwallexterior and interior design.

In his contribution to the environment we see that vertical gardens:

* Are decontaminating gardens. The concentration of plants can vary from 30-45 per m2, being able to balance air pollution by giving back cleaner air. Plants store CO2 and then filter it, allowing them to treat a volume of greenhouse gases greater than that issued by the building. The irrigation system is adapted to the climate conditions in which the building is located usually resulting in less water consumption.

* Isolate the building from the outside noise by creating a vegetable wall between the street and the building.

* Improve the building’s thermal conditions by maintaining cooler temperatures in the summer.
