Green roofs and green gardens create a human value in which the flora and fauna get a whole new living space, which has a positive effect on health and well-being. These green surfaces provide recharging and relaxation directly in the living environment, but they also have significant ecological and economic significance. Important ecological advantages of green surfaces include the retention of rainwater, the relief of the sewerage network, the maintenance of the natural water cycle, the improvement of the microclimate, and the provision of the ability to absorb harmful substances. The ecological benefits are also realized in economic benefits, among other things in the reduction of sewerage fee costs, in the increase of the quality standard of the living space, in the increase of the thermal insulation capacity, thus in the energy saving.
