Researches Regarding the Water Loss From Substrates of Vertical Garden Systems Placed in Exterior

In the effort to a durable development, is put increasingly more emphasis on the reduction of pollution, of energy consumption, of carbon emissions for, both, private buildings and industrial buildings. One way to reduce this factor is the implementation of vertical vegetal walls with climbing plants or separated structures, so-called vertical gardens.The main aim of the research is to highlight the qualities of different types of vertical gardens existing in the market currently. The research focused, in addition, on the advantages and disadvantages of vertical garden systems from technical and visually point of view. To provide a comprehensive overview about the influence of environmental factors on vertical systems, were monitored specially designed modules in order to observe the loss of water and the growth of plants used in the construction of such systems. In the experiment have been utilized 11 species of plants and 9 planting substrate, different in terms of the degree of compaction. The test consisted of daily weighing of the evidence, for a period of two months (September and October 2011). The obtained results provide a comprehensive overview about the influence of environmental factors on vertical systems, on the loss of water and the growth of plants used in the construction of such systems.
