Green roofs are becoming an increasingly fast-growing technology in the construction industry to eliminate manifestations of massive urban development. Bringing natural vegetation back cities has beneficial effects not only on biodiversity and inhabitants themselves. It also a effect surrounding climate affects building itself. Due its evapotranspiration capacity, mitigates temperature fluctuations eliminates heat island phenomenon. To function properly, vegetated structures must have optimum water supply, especially during summer. Several studies shown that absence water, for extensive roofs, significantly impacts proper functioning such structures. The presence substrate promotes formation evaporation, cools air reduces at waterproofing level. This article highlights impact irrigation summer days.

To achieve climate neutrality of existing buildings in Europe by 2050 and to counteract global warming, new strategies reduce buildings` annual energy demand are required. In hot climates, green facades applied outside wall surface temperatures through shading evapotranspiration. However, the wind barrier effect radiant heat exchange between exterior cold clear sky, which is more relevant wintertime, has hardly been reported. Therefore, this study aims simulate a ventilated living (LW) evaluate its impact on building Central European throughout whole year. Moreover, since saving potential LW depends orientation coverage percentage, sensitivity analysis was conducted determine an optimized greening scenario for simulated building. Finally, achieved savings were compared those conventional facade renovation measures. attain these goals, numerical simulations residential Germany carried out with without LW. The performed using simulation software EnergyPlus. addition, SketchUp OpenStudio used model development. Before conducting simulations, validated against consumption data from three years.To predict various constructive plant physiological parameters facades, Building Energy Modeling (BEM) essential. due complexity physical processes, only five models have developed, but none them directly implemented BEM yet. study, so-called Green Roof Model (GRM) EnergyPlus modified application vertical account longwave radiation ground. This approach can be seen as preliminary work future modifications GRM, e.g. change convective transfer coefficient at foliage substrate, consideration solar transmittance foliage. before actual reference out. air gap, each unit modeled geometrical entity separate thermal zone. For rear ventilation, test Design Flow Rate (DFR) Wind Stack Open Area (WS) algorithms. As result, speed temperature gradient dependent DFR 288 h-1 chosen. allow accurate evaluation distribution building, apartment considered zone.The comparison greened showed quantitatively higher heating than cooling, longer period climate. percentage significantly summer. Thus, 100% saved 0.1%, 22.6%, 0.24% heating, total demand, respectively. Simulating LWs different orientations greatest southeast facade. scenario, reduced 10.6%. most efficient terms façade area required.Moreover, standard measure (+5 cm Polyethylene) 4.9%. lower was. Although reduction found low climate, cooling promising. will play increasingly important role times warming.

The circular economy paradigm can be beneficial for urban sustainability by eliminating waste and pollution, circulating products materials regenerating nature. Furthermore, under an development scheme, environmental noise designed out. current control policies actions, undertaken at a source-medium-receiver level, present linearity with minimum co-benefits. A approach in strategies soundscape design could offer numerous ecologically related global literature documenting the advantages of implementation cities has highlighted mitigation as given benefit. Research involving actions such green infrastructure, walls, sustainable mobility systems electro-mobility acknowledged reduced levels major circularity outcome. In this research paper, we highlight necessity bioeconomy control. To end, preliminary experimental modeling study was conducted to showcase acoustic benefits walls electric vehicles medium-sized area Mediterranean island. results indicate level reduction 4 dB(A) when simulating introduction actions.

Walls overgrown with plants can have a positive impact on urban comfort and contribute to biodiversity in the city. In particular, quay walls, thanks their close contact water, potential be ecologically engineered encourage growth of herbaceous plants. Different factors affect vegetation walls. This research aims at experimentally investigating effect several variables, including wall design, building materials environmental conditions, receptivity brick masonry walls for To this scope, ten (size 2 m × x 0.43 m), been built placed canal city Breda (the Netherlands). The survival moisture content were monitored during period about years. results show that presence layer soil substrate high capillary suction, positioned between cladding concrete structure wall, has most relevant masonry. Mortar composition irregularities surface influence bio-receptivity too, but less extent; orientation had only limited effect. Moreover, strategy using mechanically strong bedding mortar combination weaker more bio-receptive pointing proven successful favouring plants, while providing sufficient strength
