The global scientific community is intensively promoting energy-plus buildings. Following the leading world trends, this paper presents a new energy-plus building concept—elevational earth-sheltered buildings with three different types of horizontal overhang photovoltaic-integrated panels: wooden support columns covered with clay tiles, steel pipes as support columns covered with sheet steel, and concrete support columns with concrete coverage. In this instance, the specific multi-numerical case study building model for the city of Kragujevac (located in central Serbia with favorable climatic conditions) was performed over 7 months (from 1 October to 30 April), taking into account the soil temperature, the effects of solar shading, the performance of the heating system—a ground source heat pump—and the characteristics of the artificial and automatic lighting control system. The simulation results show that the optimal depth of a horizontal overhang (energy-plus status) depends on the occupant’s habits, in addition to meteorological conditions. The presented methodology can be used for any other location, both in Europe and the world.

“…PVSDs offer dual benefits by efficiently generating electricity and simultaneously reducing cooling loads in buildings [14]. However, despite the abundance of static PVSD research in the previous literature [15], there is a scarcity of studies focusing on dynamic PVSDs. Dynamic PVSDs, though involving more complex design and operation, hold greater promise.…”

Pursuing innovations in sustainable architectural solutions, this study examines the impact of a climate-adaptive building envelope with dynamic photovoltaic integrated shading devices (PVSDs) on building performance. A major challenge in designing PVSDs is the lack of established guidelines for geometry and operations. We delve into the complexities and potential benefits of integrating dynamic PVSD designs into building performance simulations, particularly considering their time-varying geometric and operational aspects. This research assesses a range of similar PVSD design options with differing patterns, emphasizing their effects on solar energy potential, daylighting, and thermal efficiency. We conducted tests on south-oriented PVSDs (featuring two-axis rotation) in Houston, Texas, focusing on variables such as panel count (4 or 36), rotation angle range, and operational patterns (synchronized or individual). Regarding solar potential, the four-panel synchronized PVSD option outperformed static shading by 2.1 times. For daylighting and thermal performance, the 36-panel synchronized option with a wide rotation range and the four-panel individual option proved superior to other PVSD configurations, improving up to an average of 36% (sDA300/50%) and 1.5 °C, respectively. Our findings emphasize the critical role of integrating geometric design and operational patterns in PVSDs for enhanced system effectiveness and highlight PVSD design and application limitations. Our findings emphasize the critical role of integrating geometric design and operational patterns in PVSDs for enhanced system effectiveness. Furthermore, they shed light on the limitations in the PVSD design process and practical applications.

This article presents the performance analysis of a new dynamic and vertically oriented building‐integrated photovoltaic (BIPV) shading device. The work forms part of a Swiss Pilot and Demonstration project. From technology readiness levels 5–7, it aims to validate the technology's consistency and replicability in the operational building and cost‐effectiveness for marketability. The shading slats comprise two‐string PV modules realized with laminated glazing layered by an outer white satin glass pane. For the small‐scale mock‐up, two designs are compared to quantify the effectiveness of temperature reduction and energy gain: 1) optimized—each string is connected to a bypass diode, and 2) standard—two strings are connected to a bypass diode. It is demonstrated that optimized slats have consistently lower module temperatures and higher energy yield, achieving more than 20% gain during spring and summer. There are no additional risks for consideration since no extreme temperature and humidity measurements are observed for the pilot installation at the actual building. The first floor's system produces a lower specific energy yield due to partial shading. Still, it can be worsened if the standard PV is used instead, highlighting the importance of a BIPV‐specific consultancy for successfully implementing BIPV systems.
