Green is the new black in building facades. Builders are turning to steel and metal cables and grids to create vertical gardens and green facades. According to ArchDaily‘s recent article, “Using the vertical plane to maintain plants in an urban setting is a coherent and common-sense solution, especially when there is little possibility of bringing green to the level of the people on the streets.”

The article goes on to say, “Vertical vegetation works as more than just an aesthetic adornment. Plants block a part of the solar radiation that hits a building’s surfaces, making indoor spaces cooler and reducing the need for air conditioners. This measure can save electrical energy by 30% due to evaporative cooling and shading. In addition to making the air quality better, the leaves also absorb sound (research shows a decrease of up to 5 dB) and reduce discomfort due to unwanted external noise.”

A simple way to grow an urban garden is to use climbing plants with metal grids and cables where the plants cling to and grow, creating a vertical vegetation cover. The design is quite simple. There are usually small stalls, where substrates are inserted for plant roots to develop. A light structure of galvanized metal or stainless steel, resistant to weather and corrosion, is usually spaced between 5 and 20 cm from the facade, allowing the plant to grow with an ample amount of free space.
