Green roofs (GRs) belong to the third type of NbS, namely, creation new ecosystems synthetically defined as surfaces detached from ground, spontaneously colonised by plants, or intentionally greened. Their strength lies in multiple benefits (co-benefits) they offer single buildings and urban environment a whole: absorption air pollutants reduction energy consumption provision biodiversity. Concerning latter service, if GRs are designed according principle restoration ecology following habitat template approach, can play key role stepping stones becoming part ecological network green infrastructure. Conceiving landscapes instead flat homogeneous will improve biodiversity, for example, varying substrate thickness, adding small temporary ponds foreseeing areas with scattered vegetation. Among others, way select plant species communities is take phytosociological classification given characteristic, diagnostic recurrent natural stands. An accurate preliminary site analysis essential proper replicate edaphic conditions characterising it.

Green roof systems, aimed at reducing anthropic impact on the environment, are considered environmental mitigation technologies and adopted by many countries across world to strengthen urban ecosystem services. This study evaluates two mixtures of succulent: one Crassulaceae other Aizoaceae , used in creation a continuous homogenous plant groundcover Mediterranean environments. To assess species mixtures, parameters height, growth index, cover percentage flowering were observed. Hydrological observations also carried out evaluate rainfall retained test system any given month. All data subjected analysis variance. Growth indicators showed trends characteristic xeric plants, which tend slow down dry, summer climate conditions point halting vertical ground development completely. The Aizocaeae mix, during initial stage, prevalent horizontal growth, confirmed greater index (13,21) (45%) compared Sedum (Growth index: 3,61; Cover: 36%). In contrast, mix recorded beginning ( mixture: 7.53 cm; 6,11 cm). During final stages observations, however, (7,88 cm) became apparent together with recovery (79%), albeit not sufficient outperform mixture (87%). Flowering occurred between late spring summer. guaranteed longer period (130 days) (93 days), gradual start followed steady flower emission. Regarding water retention, comparison winter/early revealed that performed best (44.9 L m 2 vs 37.4 ), whilst outperformed Autumn (63 55 conjunction favorable rates both mixtures. Both demonstrated satisfying results suited environment. Furthermore, based different this suggests new combinations might prove more resilient

A green roof can modify the outer surface temperature (Tr) to influence indoor air (Ti). Green design and roof-slab thermal insulation jointly determine coupled-roof system's performance. This study investigated their joint effects on subtropical winter warming, which were seldom investigated. Custom-built houses without (bare roof) with a 20-cm soil layer at circa 20% moisture content (soil provided experiment plots collect field data.
