“…Either GIS maps or the integration of GIS and Unmanned Aerial Vehicles (UAVs) are widely used by facility managers in order to provide safety, efficiency of facilities and maintain sustainability. According to Zhang et al [19] and Sun and Zhang [20], the methodology of a spatial photovoltaic (PV) potential evolution is proposed for structural inspection of the built environment. The method based on the integration of aerial photogrammetry of UAVs and the geographic information system (GIS) can be used not only on roofs of buildings but also built environments such as roads, bridges, car parks, etc.…”

“…This method is used for outdoor carparks, roads, bridges and the rooftops of buildings in Singapore and Tibet as testing fields. The results showed that the proposed method is applicable to evaluate and inspect efficiency and safety of built environments such as carparks, corridors, reservoirs, roads and horizontal plane [19] (p. 2), [20] (p.16).…”

In this study, our aim is to present a comprehensive systematic review on digitalization (DT) in facility management (FM) and FM performance management (PM). Past research on these themes indicated that either research articles on DT in FM or research studies on FM PM are separately dealt with. However, in contrast, in our literature review, we try to present a holistic literature review by integrating both research streams on DT applications for FM and FM PM. A total 130 academic journal articles published on these subjects, between 1990 and 2021, from Web of Science and Google Scholars, were reviewed in this article. Moreover, this article identified a number of possibilities for future research on DT and FM PM, including the interoperability enhancement of building information modeling (BIM) methodology, the test and implementation of BIM concept for smart transportation infrastructure, usage of the integration of 3D analysis algorithms, the perfect cross integration of BIM and geographic information system (GIS) and systematic research efforts with new methodologies and theoretical constructs. We hope that this article will help researchers determine the areas where further research must be conducted and what kind of future directions would be valuable for DT and PM in FM.

“…(2) The building-scale photovoltaic potential analysis of buildings is mainly based on the fine 3D model of building surfaces obtained by laser scanning, or photogrammetry, i.e., the 3D BIM model constructed based on design parameters to conduct fine and detailed photovoltaic installation simulations on the surface of the building. Some scholars rely on LiDAR equipment or camera equipment and UAV equipment for the multi-platform, multi-view, omni-directional scanning of buildings to obtain high-precision point cloud/mesh 3D models, combined with solar radiation models and shadow occlusion models to realize the fine photovoltaic potential simulations of a building's surface [1,18,19]. LiDAR can be used to estimate the facade and allows facade resource analyses to be performed.…”

Photovoltaic energy generation has gained wide attention owing to its efficiency and environmental benefits. Therefore, it has become important to accurately evaluate the photovoltaic energy generation potential of building surfaces. As the number of building floors increases, the area of the facades becomes much larger than that of the roof, providing improved potential for photovoltaic equipment installation. Conventional urban solar potential evaluation methods are usually based on light detection and ranging (LiDAR). However, LiDAR can only be used in existing buildings, and the lack of semantic information in the point cloud data generated by LiDAR makes it impossible to evaluate the photovoltaic potential of facades (including details such as windows) in detail and with accuracy. In this study, we developed a method to accurately extract facades and roofs in order to evaluate photovoltaic potential based on the Industry Foundation Classes. To verify the feasibility of this approach, we used a building from Xuzhou city, Jiangsu province, China. The simulation results indicate that, out of the total building photovoltaic installable area (8995 m2), that of the facade is 8240 m2. The photovoltaic potential of the simulated building could reach 1054.69 MWh/year. The sensitivity studies of the grid resolution, the time interval and the computation time confirmed the reasonability of the determined conditions. The method proposed offers great potential for energy planning departments and the improved utilization of buildings.
