An analysis of the feasibility of using green infrastructure in public buildings on the example of a kindergarten located in central Poland

The article describes the possibility of using green infrastructure for rainwater management on the example of an existing kindergarten building located in central Poland in the town of Skierniewice in the Łódź Voivodeship. The article shows solutions for the use of green infrastructure objects such as green roofs, infiltration basins and rain gardens, which, in addition to their technical function, have a positive impact on the facility's users. These devices were dimensioned based on rainfall intensity determined using the PMAXTP model for 15-minute rainfall with a probability of occurrence of p=0.2. The individual devices for rainwater management were analysed in terms of reducing rainwater runoff into the sewage system, and the course of calculations for the selection of specific solutions was presented. The findings lead to the conclusion that the implementation of the described solutions enables a reduction in the volume of rainwater discharged into the sewage system by 53%.
