“…These results support the findings presented by Busker et al (2022), who investigated the hydrological performance of a MGR in the Netherlands. The different climatological environment leads to a different retention capacity, slightly lower in The Netherlands than in Mediterranean areas.…”

“…The buffer is made of Permavoid, a modular interlocking polypropylene void former. The storage capacity of the Polder Roof can be regulated by a smart remotely controlled valve, which can be opened or closed depending on the user's needs (Busker et al 2022). For example, as shown in Figure 1, respectively, the user could decide to open the valve when heavy rain is forecast (Figure 1 Using Metropolder's patent pending Sm^rtMILL (Figure 1(c)), the Polder Roof functions as a dynamic water buffer.…”

“…It is therefore clear that, depending on the goals that need to be achieved with the MGR installation, a different management of the gate should be evaluated to optimize the benefits of the system. Busker et al (2022) recently investigated the potential improvement of the retention capacity of a MGR very similar to those tested in this work, when integrating the gate management with the weather forecasts. This choice enables to empty the storage layer before intense rainfall events and could largely reduce the peak runoff and increases the peak delay.…”

Multilayer blue-green roofs as nature-based solutions for water and thermal insulation management

Green roofs have been widely recognized as sustainable nature-based solutions to mitigate floods in urban areas, which, in the last decades, are increasing due to the combination of intense worldwide urbanization and climate change. Besides flood mitigation, green roofs provide additional benefits for the urban environment (e.g., reducing the urban heat island and ensuring energy saving for the underneath building). Moreover, green roofs facilitate the increase of urban biodiversity, attracting different species of small animals, and upgrade the city aesthetic value. Among the different types of green roofs, multilayer blue-green roofs present an additional layer to store water during rainfall events. As part of the Polder Roof field lab project, prototypes of multilayer blue-green roof developed by the Dutch company Metropolder were installed in four Italian cities: Cagliari, Palermo, Perugia, and Viterbo. The four prototypes and the experimental set up are described and the potential benefits of this innovative solution are discussed. Preliminary analyses, from December 2020 to December 2021, enable to estimate runoff reduction and thermal properties of multilayer blue-green roofs, underlying the high potential of this nature-based solution, which allows to retain most of the rainfall events and to mitigate the daily temperature variability.

“…Some researchers have suggested blue-green roofs as a way for using rainwater for irrigating. Generally, blue-green roofs have an extra water retention layer that allows more stormwater to be stored so that the reservoir can act as a source of water for the GR through capillary rises (Busker et al 2022 ). Moreover, Droz et al ( 2021a , b ) showed that blue-green roofs provided the most services with the lowest number of trade-offs and expressed that the GR system type is the most impactful on ecosystem services.…”

Green roofs have gained much attention as a modern roofing surface due to their potential to deliver many environmental and social benefits. Studies have indicated that different GR designs deliver different ecosystem services, and there are important factors that affect GR performance. This article reviewed significant factors that influence GR performance and sustainability. Substrate and drainage layer material choice significantly affects stormwater retention potential, leachate quality, plant survival, and determines GR environmental footprints. Subsequently, type of plants, their form, and kinds used on GRs impact GR ecosystem function. Leaf area is the most studied trait due to its influence on the cooling potential and energy performance. In order to achieve a sustainable GR, it is essential to select the type of plants that have a high survival rate. Perennial herbs, particularly forbs and grass as dominant groups, are heat and drought tolerant, which make them suitable in GR experiment. Furthermore, selecting a suitable irrigation system is as important as two other factors for having a sustainable GR. Irrigation is essential for plant survival, and due to the current pressure on valuable water sources, it is important to select a sustainable irrigation system. This review presents three sustainable irrigation methods: (i) employing alternative water sources such as rainwater, greywater, and atmospheric water; (ii) smart irrigation and monitoring; and (iii) using adaptive materials and additives that improve GR water use. This review sheds new insights on the design of high-performance, sustainable GRs and provides guidance for the legislation of sustainable GR.

Sustainability has been one of architecture's most significant trends over the last twenty years. e environmental consciousness of professionals has put sustainability at the heart of the architectural profession and has contributed to adopting and implementing sustainable designs on the scale of urban landscapes. A green roof or living roof, which is a sustainable solution in architecture, is a roof on the surface of which plants are grown. e roof is covered by plants, covering the waterproof layer beneath the vegetation. However, various types of plants can be used in this scheme. Understanding the influencing factors in choosing the right plant species and the impact that utilizing green roofs has on the overall energy consumption of the building can tremendously help scientists and clarify the possible future research topics in this field. Hence, this article investigates energy optimization in the construction process of a green roof in sustainable architecture and its advantages and challenges. e results of this study show that budget limitations, managerial and organizational policies, legal issues, technical and scientific infrastructure, and cultural and geographical aspects are all affecting the widespread use of green roofs currently and need to be considered in future studies.
