Why?<\/strong><\/p>\nAffect to different issues:
\n\u2022 Overheating. Green fa\u00e7ades help to reduce the heat island phenomenon as plantations are an efficient temperature buffer.
\n\u2022 Green spaces and biodiversity: Vertical gardens can operate as connectors in an intermittent grid of green spaces and support birds movements in the city.
\n\u2022 Building energy efficiency: A green fa\u00e7ade reduces the external surface temperature and improves the thermal and acoustic indoor insulation.
\n\u2022 Climate change mitigation: green surfaces help to mitigate CO2 emissions by fixing this gas through the photosynthetic process.<\/p>\n
How?<\/strong><\/p>\nThe system is suitable to facades, dividing walls or only inside open balconies. In the case of building facades in strict alignment, it is necessary to verify, through the building council regulations, the conditions in which it is allowed to move forward the front fa\u00e7ade. There is also street furniture available made up with vertical frames as a support for vegetation.
\nDepending on the support method and location, we can choose from a variety of vertical facade systems.<\/p>\n
According to the soil:
\n\u2022 with ground planting
\n\u2022 with organic substrate
\n\u2022 hydroponics<\/p>\n
According to the support system:
\n\u2022 as facade cladding
\n\u2022 in superimposed structure with maintenance access<\/p>\n
Depending on the laying system:
\n\u2022 with modular panels
\n\u2022 non-modular<\/p>\n
According to the soil there are several systems:
\n\u2022 Soil only at the base of the wall. Used for climbing plants on the face of the wall to create the green, or vegetated, facade. Growth is supported by grids, tensors or frames attached to the facade. This system is usually called green fa\u00e7ade.
\n\u2022 With organic substrate. The roots grow in a granular medium with organic material, which gives them the capacity of water retention, aeration and drainage. Nutrients can be provided through irrigation in a greater or lesser percentage but are not essential for short-term operation.
\n\u2022 With hydroponic soil. It does not have an organic substrate as a nutrient. The plants absorb the essential minerals from inorganic ions dissolved in the water via irrigation. In these systems the roots grow in an inert medium: non-woven felt, rock wool or technical foams. The standard system is usually formed by a metal frame, to which an expanded PVC sheet is fixed with a polyamide felt. The frame, self-supporting or anchored to the wall, can leave an air chamber of a few centimeters to prevent the effect of the roots in the wall. The PVC sheet provides tightness and stiffness to the felt, which has high capillarity and water retention capacity. Irrigation operates with a perforated pipe in the upper part of the facade.<\/p>\n
The support system is usually in a layer attached to the fa\u00e7ade with a more or less simple substructure, but it may be necessary for this structure to serve as well, as an climbing frame to the different levels of the facade through stairs to be able for the necessary maintenance and control of the irrigation and disposal of fertilizers.<\/p>\n
The laying system can be with modules or pots, although the ground based type do not need it. The modules or pots can be made of different materials and measurements available, usually made of polyethylene provided with a water circuit or reservoir.<\/p>\n
The maintenance cost must be considered, so is basic a careful selection of the plant species that may be used. Likewise, the remaining water not absorved or retained by the soil, must be reused returning to the pipe circuit, avoiding uncontrolled fall trough the fa\u00e7ade, as it may cause structural damages (by humidity or insects).
\nThe structure calculation, must consider the total load value, which includes the plants weight, the structure itself, the wind and the snow load. And the maintenance access loads if it’s necessary.
\nDepending on the fa\u00e7ade size, it may be cost-effective to study the irrigation system in combination with the rainwater collect system or a grey water reuse in the buiding.[\/vc_column_text][vc_column_text]![\"\"](\"http:\/\/www.lugobiodinamico.eu\/catalogo\/wp-content\/uploads\/2021\/02\/13718.png\")
