Green roof impact on ecology, society and economy in urban areas

Zeleni krovovi u današnje urbano vrijeme dobivaju sve važniju ulogu u svijetu gradnje. Prije same izvedbe zelenog krova moramo odabrati vrstu krova koju ćemo izvesti na nosivoj konstrukciji te se dobro informirati o detaljima vezanima uz tu vrstu krova. Nadalje, potrebno je odrediti sastav zelenog krova, sa posebnom naznakom prilikom odabira hidroizolacije. Nakon provedbe ovih dviju stavki, slijedi odabir zelenog krova. Dvije su glavne vrste zelenih krovova: ekstenzivni zeleni krovovi i intenzivni zeleni krovovi. Vrste krovova biti će detaljno opisane s popratnim primjerima općih izvedba postavljanja zelenih krovova. Zelene krovove krase mnoge pogodnosti koje donose u ekologiji, društvu i ekonomiji urbanog svijeta. Ulogu zelenih krovova biti će opisane kroz te tri kategorije. U ekologiji smanjuje efekt toplinskih otoka, obogaćuje biodiverzitet, pročišćuje vodu i poboljšava kvalitetu zraka. U društvenoj disciplini zeleni krovovi, ne samo što su oku ugodni, već smanjuju buku te time vraćaju mir u život zajednice. Moguća je i proizvodnja hrane na zelenim krovovima, što u urbanim sredinama donosi i veliki plus sa ekonomske strane. Također, sa ekonomske strane, zeleni krovovi povećavaju i broj radnih mjesta. Iako je u početku potrebno veće ulaganje u izgradnju zelenih krovova od uobičajenih krovova, kasnije se uloženi kapital višestruko vrati.Green roofs in today's urban times gain an increasingly important role in the world of construction. Before the construction of the green roof itself, we have to choose the type of roof that we will carry on the load-bearing structure and be well informed about the details associated with that roof type. Furthermore, it is necessary to determine the composition of the green roof, with a special reference when selecting the waterproofing. After the implementation of these two items follows the selection of the green roof. There are two main types of green roofs: extensive green roofs and intensive green roofs. The types of roofs will be described in more detail in the accompanying examples of general installation of green roofs. Green roofs have many benefits that they bring in ecology, society and the economy of the urban world. The role of green roofs will be described in these three categories. In ecology, it reduces the effect of thermal islands, enriches biodiversity, purifies water and improves air quality. In social discipline, green roofs, not only are they easy on the eye, but also reduce noise and thus restore peace to the life of the community. It is also possible to produce food on green roofs, which in urban areas also brings a big plus from the economic side. Also, on the economic side, green roofs also increase the number of jobs. Although it is necessary to initially invest more in building green roofs than usual roofs, later invested capital is returned multiple time
