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. [ABSTRACT FROM AUTHOR]

The study proposes advanced analyses of the monastic citiy of the western coastal area of the Athos Peninsula in Greece. This research is the result of architectural and environmental survey campaigns conducted since July 2020.The current bibliographic documentation is limited, and most of the volumes focus on an art and historical description of the paintings in the monasteries, as well as on visitors' travel notes.Through the consolidated phases of the discipline of representation, such as digital surveying, point clouds and the processing of flat surfaces, a journey of knowledge of the third arm of the Chalkidiki peninsula is proposed with regard to the religious architecture considered as micro-cities.The initial part of the research was developed with photographic documentation from the sea, while in subsequent survey phase of the monasteries on the west coast was carried out.The instrumental survey activities, carried out with the help of quadrihelix drones and terrestrial photogrammetry, concerned the Monastery of St. Dionysius, the Monastery of Xeropotmus, the Monastery of Zographos, the Monastery of Dochiario, the Monastery of Simonpetra, the Monastery of St. Paul, the Monastery of Xenophon, the Monastery of St. Gregory, the Monastery of St. Pantaleimon and the Monastery of Konstamonitou.The research aims to expose, for the first time, the unpublished instrumental surveys carried out in the Athos community, which has been averse to the access of tourists and curious people for centuries.

In a post-earthquake scenario, the semantic enrichment of 3D building models with seismic damage is crucial from the perspective of disaster management. This paper aims to present the methodology and the results for the Level of Detail 3 (LOD3) building modelling (after an earthquake) with the enrichment of the semantics of the seismic damage based on the European Macroseismic Scale (EMS-98). The study area is the Vrisa traditional settlement on the island of Lesvos, Greece, which was affected by a devastating earthquake of Mw = 6.3 on 12 June 2017. The applied methodology consists of the following steps: (a) unmanned aircraft systems (UAS) nadir and oblique images are acquired and photogrammetrically processed for 3D point cloud generation, (b) 3D building models are created based on 3D point clouds and (c) 3D building models are transformed into a LOD3 City Geography Markup Language (CityGML) standard with enriched semantics of the related seismic damage of every part of the building (walls, roof, etc.). The results show that in following this methodology, CityGML LOD3 models can be generated and enriched with buildings' seismic damage. These models can assist in the decision-making process during the recovery phase of a settlement as well as be the basis for its monitoring over time. Finally, these models can contribute to the estimation of the reconstruction cost of the buildings. [ABSTRACT FROM AUTHOR]
