“…This versatile element is particularly suitable for retrofitting projects and constructing translucent facades in high-rise buildings across various climatic zones [39]. Likewise, Lee et al [40] suggested implementing a photovoltaic double-skin (PV-DSF) system to enhance the efficiency of building envelopes. This innovation resulted in a decrease of 0.5 • C and 2 • C in air and wall temperatures during the summer, consequently reducing energy consumption [40].…”

Recognizing the significance of solar energy as a vital renewable energy source in building envelope design is becoming more and more important and needs urgent attention. Exploring solar adaptation strategies found in plants offers a wide range of effective design possibilities that can substantially improve building performance. Thus, integrating solar technologies with biomimetic solar adaptive solutions could establish a suitable combination towards a sustainable design. In this context, this study follows an interdisciplinary approach to provide a link between plants’ solar adaptation strategies, building integrated photovoltaics and building envelope design. To do so, a framework has been presented using data synthesis and classification to support the potential integration of three photovoltaic (PV) technologies with plant-inspired building envelope design, facilitating a harmonizing approach between biomimetic design and the application of photovoltaic technologies in buildings.

“…For this purpose, the irradiation and power generation data were collected after fixing the OBIPV system operating angle at a closed angle of 90 degrees for approximately two months, in November and December. Conversely, as the study for the energy performance verification of the double skin façade system [29] was conducted simultaneously, the data available for validation were 24 days in November and 19 days in December. In addition, the irradiance applied during the validation test was calculated by reflecting IAM in the measured irradiance, and the power generation P * 90 was calculated using Equation (14).…”

The performance of the Operable Building Integrated Photovoltaic (OBIPV) system applied to the building envelope to reduce the building energy consumption varies significantly depending on the operation method and influence of the surrounding environment. Therefore, optimization through performance monitoring is necessary to maximize power generation of the system. This study used temperature-corrected normalized efficiency (NE*) to evaluate the power generation performance of the operation methods and predict that of the OBIPV system based upon the measured data. It was confirmed that power generation performance decreased when the photovoltaic (PV) operation angle changed, the system remaining the same. A decrease in power generation performance due to partial shading from an overhang was also observed. As a result of the power generation prediction for two months using NE*, the error of the measured values was found to be less than 3%. In addition, with or without any partial shading of the OBIPV system, its performance degradation was predicted with an annual electricity generation decrease by 36 kWh/yr (6.5%). Therefore, NE* can be used as an indicator for evaluating the power generation performance of PV systems, and to predict generation performance considering partial shading.

“…A few papers have also evaluated the influence of DSFs on the thermal comfort provided to occupants (Yang et al [6]) and energy consumption (Radmard et al [7] and Ahriz et al [8]). For example, the implementation of a photovoltaic DSF system was analysed in Lee et al [9], and the application of DSF systems in several kinds of buildings, including residual buildings, was analysed in Zang et al [10].…”

The DSF (double-skin facade) system is an important element in building design and is used in adjacent spaces to control the inlet solar radiation, heat the air, reduce energy consumption, decrease the acoustics levels, and produce photovoltaic energy, among other improvements. The DSF system can, for example, be used in winter conditions to heat the air, which is then transported to non-adjacent spaces to improve the thermal comfort level and the indoor air quality that the occupants are subjected to. Smooth DSF systems, which are a focus in the literature, are subjected to higher solar radiation levels at a specific hour of the day. The semi-circular DSF system used in this work, which was built from a group of smooth DSF systems with different orientations, guarantees the reception of the highest incident solar radiation throughout the entire day. This work presents a numerical study of a new DSF system, called the semi-circular DSF. The DSF system consists of a set of 25 smooth DSFs with different orientations, each one consisting of an outer glazed surface and an inner surface provided by the outer facade of the auditorium, both separated by an air channel. In this work, the influence of the radius of the semi-circular DSF system and the opening angle of the DSF system on the thermal response of the auditorium was analysed. Thus, six auditoriums were considered: two sets of three auditoriums with radii of 5 m and 15 m, with each of the auditoriums having a different DSF opening angle (45°, 90°, and 180°). It was found that the greater the radius of the semi-circular DSF and the opening angle of the DSF system, the greater the area of its glazed surface and, consequently, the greater the availability of solar heating power. Therefore, during the occupation period, only the set of auditoriums with the largest semi-circular DSF radius managed to present acceptable levels of thermal comfort, which were verified from mid-morning until late afternoon. As for the opening angle of the DSF system, the influence was not very significant, although slight improvements in thermal comfort were noted when the value of this angle was reduced (see Case F as an example) due to the corresponding decrease in the volume of indoor air to be heated. In all auditoriums (see Case A to Case F), it was verified that the indoor air quality was acceptable for the occupants, so the airflow rate was adequately promoted by the ventilation system.
