“…Furthermore, the estimate of CO 2 that is permanently sequestered by the plants has been measured based a specific model [15], that quantifies the accumulation of carbon in a sequence of environmental sections: 1) CO 2 absorption by plants; 2) CO 2 contained in the residual biomass by pruning operations; 3) carbon held in the plants' composting process; 4) carbon deposited onto agricultural soil in the form of compost; 5) carbon assimilated by microorganisms and permanently held in the soil. The results of this analysis show that the plants incorporated into the VGS absorb CO 2 from the atmosphere and permanently store it in the soil at a quota of 90 kg CO 2 per year (this value refers to the 98m 2 VGS with an assorted composition of herbaceous perennial plants).…”

Vertical Greenery Systems (VGS) are relatively light structures anchored on building facades with plants embedded on felt layers and nurtured by a hydroponic watering system. These systems can have positive effects on environmental performance at both the building scale (i.e. energy saving for cooling) and the urban scale (i.e. urban heat island effect mitigation). A research project, namely GREENED, has been developed for detecting the environmental profile of VGS based on lifecycle processes. Systemic indicators, such as Carbon Footprint (given in kg CO2-eq) and eMergy (given in solar emergy Joules -seJ), can provide information on environmental impacts or costs, due to the manufacturing and sustenance of VGS, and benefits, in terms of energy saving or other ecosystems services (e.g. CO 2 sequestration by plants). The cost to benefit ratio allows for a comprehensive evaluation of VGS sustainability. Outcomes from a case study (i.e. 98m facade on a 1000m building) reveal that, in given conditions 2 3 (i.e. massive wall envelope, south-oriented facade, open air-cavity, integrated water harvesting system, local recourse use), environmental costs can be compensated by benefits within 25 years. This allowed for a deeper understanding of lifecycle processes and the conscious use of VGS in an urban context.

“…A dynamic model can be used to evaluate CO 2 sequestration in VGS, which included the processes from planting and growth of perennial herbaceous plants to the end of their lives, also considering return of carbon to soil elsewhere after composting the green residues. The species and biological properties decide carbon sequestration in plant tissues [4]. Studies on CO 2 sequestration of vertical greenery systems are few.…”

“…Studies on CO 2 sequestration of vertical greenery systems are few. Marchi et al selected herbaceous species as vertical greenery that hypothetically installed on a building facade [4], to evaluated CO 2 sequestration and permanent removal of C, and his model predicts that carbon dioxide accumulation increase continually in the VGS over time, indicating a 98 m 2 VGS captures average carbon dioxide sequestration about 13.41-97.03 kg CO 2 per year. Therefore, VGS is a feasible measure for climate change mitigation in urban areas.…”

“…Vertical greenery systems (VGS), known as the greening of the facade of building walls [2]. VGS have a positive influence on the comfort and well-being in and around the building [3], can offer numerous ecological and environmental benefits as innovative components of urban design and increase greenery in built environments lacking green areas [4][5], which is still a relatively new discipline and has become one of the most rapidly developing fields in the worlds of ecology, horticulture and the built environment [2]. Many factors affect performance of VGS, such as plants species, substrate type, orientation and dimensions and so on.…”

Abstract. For high-density urban environments, vertical greenery is often employed as one of feasible alternatives of environmental improvement. Vertical greenery systems (VGS) are being served as an interesting measure to improve the quality of life and urban environments, but only a few studies have examined overall performance of VGS. Vertical greenery has potential benefits, including reducing the surface temperature of buildings facades and diurnal temperature fluctuation, alleviating Urban Heat Island and noise pollution, reducing g heat flux to the building and energy cost, transforming the urban landscape and enhancing visual effect and so on. This paper provides a literature review for VGS studying, including VGS classification and their effects on acoustic insulation, thermal, air flow and temperature, energy performance, CO 2 sequestration and microclimatic layer.

“…The contribution of NUAs in terms of carbon uptake has been evaluated through the application of a carbon sequestration rate (kgCO 2 /m 2 y) for each vegetation cover. Potentials of carbon sequestration and storage values for herbaceous vegetation, shrubs and trees have been collected from literature [8], [9], [10] and respectively applied with an average value to the three selected land cover types (Tab. 2).…”

Non-urbanized areas (NUAs) play an important role in reducing the effects of climate change by providing both carbon storage and sequestration. Despite their importance, they are endangered by urbanization pressures and often neglected by local spatial planning practices. On the contrary, NUAs should be protected and designed as new public urban green spaces to enhance the amount of vegetation of different land cover types and therefore their potential capacity of carbon sequestration. This study proposes a three steps-method for enhancing carbon sequestration of NUAs through the implementation of new public green spaces while ensuring the related economic feasibility of urban development based on a Transfer of development rights program.
