Green wall A green wall is a wall partially or completely covered by vegetation and also includes an artificial growing medium instead of soil and an irrigation system with drainage. Depending on the size of the wall and the solar orientation, different plants would be recommended to achieve a perennial green effect. The benefit for the property where this wall is installed is energy efficiency fundamentally due to the evapotranspiration-transpiration of the plants. Additionally, the value of the property will increase and it will create many indirect effects on people’s well-being, including the absorption of polluting materials and CO2. The most apparent benefit is the improvement of well-being given the visual satisfaction and the reduction of pollutants in the air we breathe. Benefits Integrating a green wall of live plants into your home can have many benefits Thermal insulationc Countless studies show that when a green wall is installed on a wall that receives many hours of sun, the temperature of the wall is palliated due to the creation of a layer of air, the shade the plants cast, and their evapotranspiration Acoustic isolation Like a green roof, a green wall muffles noises from the outside Heat island effect: A greener city, a city that breathes, is a city with moderate temperatures. Vegetation creates a climate of freshness around it that wouldn’t be there on a harder surface Reduction of CO2 emission: CO2 emissions would wane because: Plants absorb it The heat island effect would be palliated Other CO2 emitting forms of insulation would be discontinued. Urban biodiversity: Increases urban biodiversity by maintaining the green corridors that range from Collserola to the Mediterranean Sea Increases the m2 of green / inhabitant ratio Pollutant particle absorption: Absorption of polluting particles such as NOx and PM10 Economic aspects: Appreciation of the farm Frequently asked questions about Green wall Will green walls cause water leaks and moisture? The green walls have a series of vertical layers. The first layer is a waterproof sheet to prevent moisture. How are green walls installed? A green wall or vertical garden begins with a rigid waterproof layer, followed by a geotextile from which the pockets are formed. Inside the pockets grown plants are planted, they will be fed semi-hydroponically through irrigation pipes that supply water and minerals accumulated in a tank. A naturalized wall consists of climbing plants that grow horizontally in planters or directly on the ground and climb metal cables or attach to the wall. What kind of green walls can be installed? One way to naturalize a wall and get the most out of it is to make a wall with climbing plants that grow from a planter. The cost and maintenance of this solution is low but you have to wait to get results. On the other hand, if you want a vertical garden from the start, a solution that is more impactful and at a higher price is to establish a vertical growth medium with hydroponics (contribution of minerals through water). The plants will be green and large as long as the system is kept in good condition. What is the approximate cost of a green wall? A naturalized wall can have a cost starting from 80 € / linear meter while a vertical garden starts from 350 € / m2 including irrigation. What is the maintenance of the green walls like? Naturalized green walls require almost no maintenance. Vertical gardens need a specialized bi-monthly maintenance. Latest projects of Green wall Experimental Green Wall At NestThrough a grant received through... +Experimental green wall at Nest Through a grant received through the "Impulsem el que fas" program, from the City Council of Barcelona, we have been able to carry out this project by testing three types of agricultural green wall systems in three different orientations and climatic conditions. The project has been installed at the Nest de Apocapoc headquarters, an industrial warehouse renovated with permaculture techniques in Poble Nou. The main objective of the project is to change the approach to sustainable nutrition and link it with concepts of circular economy and ecological agriculture. They want to raise awareness that it can also be grown vertically, albeit in a limited way. This is precisely what we want to teach and evaluate: which systems work best and what can be planted in each system. We will measure the results of the project with the following indicators: 1-Number of vertical wall typologies tested. 2-Production of horticultural crops associated with each type of wall. 3-Orientations and climatic conditions of the walls. 4-Number of visitors 5-Number of guided visits to the experimental wall. We hope to spread values, such as circular economy, urban and vertical agriculture, 0 km and seasonal food, environmentalism, and self-management. We hope to enlighten minds and awaken curiosity by showing that projects that encompass new consumption systems are possible and that everyone can successfully implement them. At the same time, we hope to make visible solutions to architectural barriers in urban areas, along with the reconquest of green. This project, together with that of Nest, is a formal declaration that the city needs green and that it is time to re-evaluate the newly implanted square meters of green in Barcelona. We intend the green wall project to be a benchmark and a laboratory for new proposals and solutions.
