Enhancement of Building Thermal Performance: A Comparative Analysis of Integrated Solar Chimney and Geothermal Systems

Abstract

A comparative investigation is conducted, employing Computational Fluid Dynamics (CFD) simulations to study two distinct room space configurations: one featuring a solar chimney and another integrating both a solar chimney and a geothermal system. The primary objective of this investigation is to scrutinize the thermal behavior, energy efficiency, and mass flow rates of these systems. Results underscore the considerable positive implications of the geothermal system integration. This amalgamation precipitates diminished average room temperatures and elevated mass flow rates, signifying superior thermal comfort and energy performance. The room implementing the geothermal system exhibited an average temperature of 302.2 Kelvin and a mass flow rate of 4.134 × 10 −6 kg/s, in contrast to the room without the geothermal system, which demonstrated an average temperature of 309.6 Kelvin and a mass flow rate of 1.878 × 10 −6 kg/s. These findings have practical repercussions for architects, engineers, and policymakers, facilitating well-grounded decisions in the domain of sustainable building design. The observed enhancement in thermal performance and mass flow rates underscore the potential merits of integrating geothermal systems, thereby promoting wider acceptance. Further research is recommended to investigate the influence of varied climatic conditions, building orientations, and room layouts on the efficiency of integrated solar chimney and geothermal designs. Examination of alternative renewable energy sources (RES), innovative building materials, and technologies is also suggested to elevate energy efficiency and sustainability in room space designs. This study contributes substantially to the expanding realm of sustainable building design, providing valuable insights for refining room space performance, curbing energy consumption, and heightening thermal comfort. By highlighting the advantages of renewable energy integration, particularly geothermal systems, the study stimulates the development of more energy-efficient and environmentally friendly building spaces.
