Solar Chimney Performance Driven Air Ventilation Promotion: An Investigation of Various Configuration Parameters

Abstract

Climate change represents a vital public health challenge, resulting in serious impacts that require passive strategies in the built environment sector to mitigate such impacts. Such strategies are associated with the Sustainable Development Goals (SDGs), which present a vital need. Consequently, the solar chimney (SC) can be considered as an effective passive strategy to provide energy, thermal comfort, and air ventilation performance. Therefore, this study focused on SC performance and its related significance on air ventilation. This study aimed to bridge the gap in previous studies and indicates the hotspot topics to conduct a conceptual framework with three phases that can integrate various configurations of a SC with various buildings by considering the recent tools of numerical analysis. Thus, a bibliometric analysis based on the Biblioshiny and VOSviewer tools within the scope of the SC and air ventilation promotion was accomplished. Then, various configuration parameters related to SC performance-driven air ventilation are provided. The results indicate that further studies are required to develop themes like the “building design” of SC and its associated effects such as air quality and ventilation, in addition to “numerical analysis” and “optimization” in terms of hotspot topics and the potential for future consequences. Additionally, limited configurations of previous studies provide promising investigations resulting in several applications including many zones and floors that can be achieved by the proposed conceptual framework. Various insights and possibilities can promote numerous configuration parameters related to SC performance-driven air ventilation promotion, which serves as research guidance for designers and specialists toward the mitigation of climate change impacts and attaining the SDGs.

Efficiency Assessment on Roof Geometry and Trombe Wall Shape for Improving Buildings’ Heating Performance

“…In the summer, the relative humidity is around 67% and the air temperature under the shade is around 43 • C. In addition, during the daytime in winter, the outside air temperature of ten ranges between 10 • C and 20 • C, and in the event of insufficient or irregular rain, it might fall to less than 1 • C at night. For other required values, sample values given in studies in the literature were used [36][37][38][39].…”

“…In this study, ANSYS-CFX (15.0) software, a commercial CFD tool, was employed to simulate the thermal and fluid dynamic behavior of the T-wall system. This software utilizes the finite volume discretization approach to solve the governing equations in the computational domain [38,39]. Figures 1 and 2 display the six configurations of roof geometry and the two configurations of T-wall geometry.…”
