A city administration asked us to examine the effect of a schoolyard redesign on the provision of ecosystem services. The upper figures show particulate matter filtration and cooling performance under the current situation. The dark green areas essentially represent shrub and tree vegetation. The future enrichment with additional vegetation in the figure on the right suggests an increase in PM10 filtration from 108 kg/ha per year to 150 kg/ha per year. The cooling capacity is higher the lighter the areas become. This means that there is an improvement in cooling capacity of 0.5 Kelvin in the lower example compared to the upper one. The orange bar displays the actual ecosystem service performance in relation to a theoretical maximum (green bar) of a completely forested area. Compared to the baseline value, the cooling capacity has improved by 18% (0.34 à 0.4). EnhancES also enables quantitative statements to be made about further changes in the OSL. This allows the schoolyard to be optimized from an ecological perspective.
