Reducing CO2 concentration in city centres with green roofs implementation: Case study Belgrade, Serbia
Abstract
This paper presents the results on reducing CO2 concentration with green roofs implementation in a densely populated urban area in Belgrade city centre. The buildings on which green roofs are implemented have an average height of 15 meters. In order to investigate the impact of existing residential urban blocks and potential retrofitting model on CO2 concentration, base model was designed (the model fully complied with the actual status and real conditions in the location) as well as retrofitting models (which present base model with added elements of extensive and intensive green roofs) and numerical simulations of CO2 concentrations for all presented models were done. Differences in CO2 concentrations at height of 1.5 m (pedestrian level), 7.5 m and 17.5 m at 7 am and 7 pm, on a typical summer day in Belgrade were investigated. ENVI-met software was used to perform the simulations. The resultant data of numerical simulation showed that utilizing the green roofs instead of classical f...lat roofs in Belgrade climatic area could reduce atmospheric concentration of CO2 around the building up to 11%, average 2.3%. By using proposed strategy, it is demonstrated that applying vegetative roofs could be valuable instrument for noteworthy contribution to environmental protection in Belgrade and for climate change mitigation, both local and global.
