“…In the same context, according to a study on Australia's city of Melbourne, the majority of the city's solar energy potential is provided by PV rooftops. It is demonstrated, however, that the PV prospective of windows becomes more pronounced for specific buildings with high compactness of glazed and high-rise buildings (Panagiotidou et al, 2021). The technological workflow described here allows various cities to simplify decision-making regarding the achievement of PV in urban settings (Panagiotidou et al, 2021).…”

Building-integrated solar photovoltaic (BIPV) systems have gained attention in current years as a way to recover the building’s thermal comfort and generate sustainable energy in building structures. BIPV systems can provide shade against sunshine while generating ancillary electrical power. Over the last decades, engineers have been trying to improve the efficiency of BIPV systems. BIPV systems with various installation types, including rooftop, balcony, curtain, sunshade, and wall façade types, are being constantly researched and intensively presented for improving power efficiency and reducing air-conditioning use. This work provides an overview of solar BIPV systems and focuses particularly on existing applications of the bifacial type of BIPV systems. The motivation and an overview of BIPV systems are first introduced, followed by the study methodology considered and the contributions. This work discusses PV technologies of bifacial PVs (monocrystalline and polycrystalline bifacial modules), BIPV installation [curtains, rooftop, flat rooftop, transparent faced, balcony windows (transparent), wall opaque facade, flat roof-faced, and skylight sunshade types], simulation and optimization software (simulation software and future trends), zero-energy BIPV technology, and optimization techniques of BIPV systems. Last, suggestion amendments to the current BIPV design that possibly contribute to growing the system’s effectiveness, reliability, and cost as future design theories for the whole system are presented.

“…Growing energy demands have put enormous pressure on the current energy infrastructure, , in which the construction industry irreversibly consumes 40% of the world’s total generated energy. , Especially noteworthy are the various problems faced during the operation of a commercial building, such as drastic temperature changes in winter and summer, light intensity differences between cloudy and sunny days, intense ultraviolet (UV) radiation at the top floors, etc. All these factors can collectively drastically increase the energy consumption and costs associated with indoor temperature control, shading, and lighting. − As an important component connecting the interior and exterior, windows directly affect the internal temperature and lighting of a building. , Therefore, numerous studies have been conducted to develop high-performance smart windows that can modulate indoor temperatures and light. − …”

High-performance interlayer materials have garnered considerable interest owing to their low manufacturing costs and applicability in smart windows. In this study, a novel smart-window interlayer material capable of selective shielding against both near-infrared (NIR) and ultraviolet (UV) radiation is developed based on the light transmittance control mechanism. An excellent thermoresponsive liquid, denoted as CDs@TRL (viz., carbon quantum dots at thermal-responsive liquid), is synthesized by compositing biomass-based fluorescent carbon quantum dots (CDs) and poly(N-isopropylacrylamide) (pNIPAM) at natural ambient temperature and in an aqueous phase. Due to the characteristics of CDs and synergistic effect of hydrogen bonds, CDs@TRL exhibits a high specific heat capacity (4.41 kJ kg–1 K–1), large thermal storage capacity (264.6 kJ kg–1), and better UV–NIR-blocking properties, compared to pure pNIPAM, as well as improves the sensitivity of thermal response. When injected into a window as a liquid interlayer, CDs@TRL can intelligently adjust the light transmittance according to ambient light intensity to achieve an intelligent response. The shielding rate of a 10 mm-thick CDs@TRL composite liquid against UV radiation (200–400 nm) was more than 95% in an overcast environment with insufficient light and close to 100% in a well-lighted environment. In addition, CDs@TRL is a cost-effective material that can be prepared from a wide range of raw material sources using a simple preparation process and exhibits excellent mobility and recyclability. Because of these features, it is considered to be a promising candidate for developing energy-saving and climate-adapted smart windows.

“…In the paper, we employ a two-fold method to shed light on such comparison: a review and an experiment on extracting information about the built environment. Our literature review is systematic, while the experiments we conducted are focused on buildings since they are the predominant feature of the built environment and a topic that is frequently the subject of both perspectives (Panagiotidou et al, 2021;Ogawa et al, 2021;Wang et al, 2021;Zhang et al, 2021Zhang et al, , 2022.…”

Abstract. Street view imagery (SVI) has gained prominence in the past decade, offering a new perspective to map and understand cities. It supports numerous studies in the built environment, by replacing or supplementing aerial and satellite imagery, where some studies have not yet been possible with traditional platforms and have now been enabled for the first time thanks to the increasing volume of SVI data. However, the two perspectives are often disconnected and there has not been an overarching paper to discuss the pros and cons of each. We provide an overview outlining and discussing the role of SVI in GIS and urban studies spanning six use cases. Our discourse is supported by a systematic literature review of more than 100 papers and our own experiments that reveal the added value and challenges of SVI in extracting information on buildings and other urban features, an increasingly important use case. We find that the key advantages of SVI over aerial imagery are that it represents more closely how streetscapes are perceived by people and that it enables extracting certain information that otherwise cannot be gathered from top-down perspectives. However, the spatial coverage of SVI tends to be limited to the vicinity of driveable roads, and its temporal coverage is comparatively sparse.
