For many years now, urban planners, architects and greenery designers all over the world have been looking for solutions that would make life in cities more human-friendly. One of such solutions is the introduction of green vegetation on the walls and roofs of buildings that have been dead so far. The benefits of using green roof systems have long been known. First of all, green roofs significantly mitigate the urban climatewhich significantly differs from the climate of the surrounding areas. Roof surfaces and building walls act as heat accumulators. Thus arises the phenomenon of the so-called "Heat islands", which causes an increase in air temperature in the centers of urban agglomerations by an average of 1-2 ° C (in extreme cases up to 10 ° C) and a decrease in its humidity. The vegetation placed on the roofs of the roofs, through the evaporation of the accumulated water and reflection of solar radiation, creates something like an "air cushion" with higher humidity and lower temperature (a roof covered with bituminous roofing heats up to 60-70 ° C in summer, a green roof only 25-40 ° C). On the other hand, a two-centimeter layer of greenery is able to retain about 50-60% of rainwater, which is then evaporated, thus they increase air humidity and relieve the municipal sewage system, enrich the air with oxygen and reduce CO2 content. A roof with an area of 15 m2 annually produces oxygen for 10 people. At the same time, it can absorb as much as 10-20% of dust and gases from the air. Green roofs significantly (by about 20 - 30 dB) reduce road noise by reflecting and partially absorbing sounds. Green roofs also act as additional roof insulation , both thermal and protecting the roof covering against external damage (wind damage, damage by birds, changes under the influence of solar radiation, etc.). Such systems allow to recover the biologically active area lost for development , which allows the full use of small plots in city centers without colliding with local zoning plans. The use of vegetation on the roofs and facades of buildings is an important element of architectural space shaping.It allows you to hide the installation devices located on the roof, create homogeneous compositions by combining greenery at different levels: vegetation in the apartment, on the terrace, on the roof and around the building, as well as creating characteristic plant elements that distinguish individual buildings. One of the greatest architects of the twentieth century, Le Corbusier, who called the roof "5th elevation", wrote that: "(...) The roof - the garden will be a favorite place to stay in the house, besides it means for the city to recover all lost for development ". He believed that roof gardens would bring people closer to nature, and for this reason he placed their construction at the forefront of his program of new architecture. Today, when we need more and more houses, factories, offices, shops, streets and parking lots, Le Corbusier's message takes on a special expression: the use of new places, where green areas may be created, becomes a necessity.
