“…The methodological analysis approach consists of a logical sequence of six steps (Figure 3). It is based on two complementary methodologies developed in Switzerland: the first one for mapping the solar potential of the existing building stock (both roofs and façades) [20], and the second one for detailing the potential of installation for Building Integrated Photovoltaic (BIPV) systems in urban areas of the Ticino Region [6,12].…”

“…The approach is applied on a case study located in Trondheim (Norway) (Section 2.2), where integrated design solutions to exploit solar energy potential are continuously increased (Section 2.3). The approach couples existing validated tools with new methods [e.g., Façade Active Solar TICINO (bFAST) [6,12]] in a logical sequence of six steps described in the methodology section (Section 3). Its application is presented (Section 4) and discussed (Section 5) in relation to local conditions.…”

Rapid and uncontrolled urbanization is continuously increasing buildings’ energy consumption and greenhouse gas emissions into the atmosphere. In this scenario, solar energy integrated into the built environment can play an important role in optimizing the use of renewable energy sources on urban surfaces. Preliminary solar analyses to map the solar accessibility and solar potential of building surfaces (roofs and façades) should become a common practice among urban planners, architects, and public authorities. This paper presents an approach to support urban actors to assess solar energy potential at the neighborhood scale and to address the use of solar energy by considering overshadowing effects and solar inter-building reflections in accordance with urban morphology and building characteristics. The approach starts with urban analysis and solar irradiation analysis to elaborate solar mapping of façades and roofs. Data processing allows assessment of the solar potential of the whole case study neighborhood of Sluppen in Trondheim (Norway) by localizing the most radiated parts of buildings’ surfaces. Reduction factors defined by a new method are used to estimate the final solar potential considering shadowing caused by the presence of buildings’ architectural elements (e.g., glazed surfaces, balconies, external staircases, projections) and self-shading. Finally, rough estimation of solar energy generation is assessed by providing preliminary recommendations for solar photovoltaic (PV) systems suited to local conditions. Results show that depending on urban morphology and buildings’ shapes, PV systems can cover more than 40% of the total buildings’ energy needs in Trondheim.

“…Besides the open data 3D city models released by local authorities (Schrotter and Hürzeler, 2020;Lehner and Dorffner, 2020), an increasing number of 3D city models are derived by conflating open datasets (Stoter et al, 2020;Kolbe et al, 2015). Such datasets originate from authorities and volunteered geoinformation, and have proven to be valuable in various spatial analyses (Saretta et al, 2020;Biljecki et al, 2016).…”

Abstract. This article investigates the current status of generating 3D building models across 11 countries in Southeast Asia from publicly available data, primarily volunteered geoinformation (OpenStreetMap). The following countries are analysed: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Timor-Leste, and Vietnam. This cross-country study includes multiple spatial levels of analysis: country, town, and micro-level (smaller neighbourhood). The main finding is that authoritative data to generate 3D building models is almost non-existent while building completeness in OpenStreetMap is highly heterogeneous, yielding location-dependent conclusions. While in general just a fraction of mapped buildings has height information and none of the administrative areas provides sufficient information to generate 3D building models, on a micro-level some areas are fully complete, providing a high potential to generate 3D building models on a precinct scale, which may be useful for certain spatial analyses. Furthermore, some areas have high building completeness, requiring only half of the work necessary for the extrusion: the collection of building height attributes. As a part of this work, a semantic 3D building model of a selected set of buildings in Singapore has been generated and released as open data (CityJSON), and the developed code was open-sourced.

“…In newly build buildings, the application of the first type of installation is a better solution. The usage of active building materials, such as photovoltaic tiles instead of conventional ones, is characterized by good results without an additional place to install PV systems [3,18].…”

The community all over the World has to tackle the problem of depletion of fossil fuels, overusing the natural resources, and growing emission of greenhouse gases into the atmosphere. It is related to the growing demand for electricity due to global development in every field. The solution to this problem can be production clean, solar energy with the use of photovoltaic modules. However, the installation of PV system in urban areas is very often impossible because of high-density citie’s architecture. The objective of this study was to analyze building applied photovoltaic system configurations for the flat rooftop of the detached house in Warsaw, Poland. Four configurations were analyzed taking into consideration the area of the rooftop, different tilt angles of PV modules, and shading areas. The system configuration as well as monthly energy output were carried out by the use of DDS-Cad software. The ecological aspect of the photovoltaic installation was also analyzed. A significant reduction of greenhouse gases was observed based on conducted calculations.
