Sažetak
Climate change and its effect on Urban Heat Island is still a major challenge. One of the strategies to keep a balanced environment is by increasing the areas with green and blue roofs in urban areas. Many research showed that it can reduce the amount of storm water that rushes in sewer system, lower cooling and heating costs, improved sound absorption and air quality, increased habitat promoting biodiversity and prolong roof life. In practice, the reason of their rare occurrence on the city roofs are the cost for constructing and maintaining green roofs and the question of ownership. This paper tried to identify main issues when choosing the best types of green roof and evaluate their costs and benefits. The problems are often the price of the material needed for constructing green roof and the transportation cost, specially concerning the substrate. With that in mind the concept of the brown biodiverse roof has been created. Although the use of recycled brick and concreate from a local recycling area sound very ecological, there can occur many problems. Due to the complexity between the plant species, soil type and height, and the site weather conditions, the question of proposing the green roof with minimum soil or an alternative growing medium for plants is raised. The feasibility of such lightweight green roof can have a far-reaching effect through quantity of square meters created due to easy to install system. However, this roof type depends on organic content or adding fertilizers in regular intervals. So, some issue concerning long term maintenance costs still needs to be addressed. Also, this paper suggested further investigation on finding best combination ratio of brown, blue, lightweight and extensive green type on one roof or to choose one on the base of costs and benefits in order to achieve sustainable solution for urban environment.
