Sažetak
Green technologies and their possible applications lately promote the installation of green roofs. In Croatia, there is lack of legislation or regulation for the construction of green roofs. It covers a When planning green roofs, the most attention is paid to the impact of the system on the building ; leakage / drainage, load on the structure, fire protection, etc. Thus living elements such as substrate and vegetation remain on the margins. The rationale for the research was to identify elements that can ensure an integrated approach to planning and implementation of green roof systems. Defined by specific climatic conditions, the possibility of using local materials and soil to create special substrates for green roofs, it is important to determine optimal soil dept level for specific plant categories and the use of indigenous species in the planting plan. The general categorisation of special substrates for green roofs is divided into three main types ; (1) substrate for intensive, (2) simple intensive and (3) extensive green roof systems. They are defined in accordance with the FLL regulations (“Richtlinien für die Ausführung und Pflege von Dachbegrünungen” / “Directives for Green Roof Planning, Implementation and Maintenance”) through: pH value, balanced provision of nutrients, water and air, water holding capacity, drainage and technical suitability. Within these parameters, it is still possible to make a mistake in selecting an adequate system. The microclimatic conditions of the site define the selection of plant species. So, the selected species must be correlated with specific substrate parameters. Plant selection is crucial especially because of long-term maintenance (nutrient content, pest and disease problem, effective drainage, weed reduction) of the green roof system since it is an unrealistic option to expect completely maintenance-free green roof. Also, this research proposes additional expert studies that will propose guidelines adapted to the local climate. It would contribute to the quality and simplicity of installation of green roof systems and give an overview of available options when resources are limited ; economic, technical or plant based.
