Prednosti i mane zelenih krovova PDF Print E-mail

Zeleni krovovi pored estetsko-funkcionalne namene imaju veliki broj prednosti u odnosu na obične krovove :

- Imaju funkciju da ublaže 'heat island' efekat. Tokom letnjih dana, beton može da dostigne temperaturu od 70°C, a zeleni krov smanjuje ovu temperaturu i za 40°C.

- Zgrada je hladnija leti i toplija zimi, pa se samim tim nerasipa energija na klima uređaje

- Apsorbuju zagađenje iz vazduha- Zeleni krovovi stvaraju svoju mikro-klimu

- Apsorbuju padavine i smanjuju opterećenje na kanalizacioni sistem tokom kiša i otapanja snega, pa i gradske vlasti imaju koristi, jer ne moraju da ulažu u proširenje kanalizacionog sistema

- Zeleni krovovi takođe smanjuju nivo buke za oko 50 dB, (što je na nivou žamora ljudi u restoranu)

- Nude atraktivnu alternativu standardnim krovovima

- Podižu ekološku svest građana

- Služe kao životno okruženje za ptice, insekte i male životinje

- Zeleni krov štiti krovnu izolaciju i materijal od UV radijacije i ublažava dnevne fluktuacije temperature, što po nekim ispitivanjima duplo produžava vek trajanja krovnog sistema

- Nekretnine sa ovakvim arhitektonskim rešenjem imaju veću tržištnu vrednost, a pa investirana sredstva se često otplate prodajom same nekretnine

Zeleni krovovi imaju i svoje mane:

- Inicijalna investicija je uglavnom veća od konvencionalnog krovnog sistema

- Opterećuje zgradu dodatnom težinom

- Zelene krovove treba održavati i brinuti da su biljke zdrave, jer bolest jedne biljke lako inficira druge biljke

- Ekstenzivni zeleni krovovi imaju trošak održavanja na svakih 6 meseci do godinu dana u zavisnosti od biljaka, a intenzivni treba da se održavaju na svakih mesec, dva.

Green roofs in addition to the aesthetic-functional applications have a number of advantages over conventional roofs:

- They have a feature to ease the "heat island" effect. During summer days, the concrete can reach a temperature of 70 ° C, and the green roof will reduce this temperature and 40 ° C.

- The building is cooler in summer and warmer in the winter, and therefore nerasipa energy to air conditioning

- Absorb pollution from the air-green roofs create its micro-climate

- Absorbing rainfall and reduce the load on the sewage system during rain and melting snow, and city authorities have used, because they do not need to invest in the expansion of sewerage systems

- Green roofs also reduce noise levels by about 50 dB (which is at the level Zamora people in the restaurant)

- They offer an attractive alternative to standard roofs

- Erected environmental awareness of citizens

- They are the environment for birds, insects and small animals

- The green roof protects the roof insulation material from UV radiation and reduces daily temperature fluctuations, which according to some surveys twice extended the life of roof systems

- Properties with such architectural features are more tržištnu value, and invested funds are often repay themselves by selling real estate

Green roofs also have their disadvantages:

- Initial investment is usually higher than conventional roof systems

- Added weight increases the building

- Green roofs should be maintained and worry that the plants are healthy, because one plant diseases easily infect other plants

- Extensive Green roofs have the cost of maintenance every 6 months to a year, depending on the plant, and the intense need to be held every month or two.
