Optimization of thermal comfort in buildings via analysis of a trombe wall for enhanced energy efficiency

Abstract

This study investigates heat transfer phenomena in a building envelope in Bechar, Southwest Algeria, under arid climatic conditions. The meteorological station Energarid provides precise recordings of solar radiation and outdoor temperature. A calibrated model is used to analyze diurnal temperature variations. Wall temperatures exposed to solar radiation are estimated using recorded data. The heating power requirements of the building envelope are determined through a thermal balance approach based on the regulatory technical document from the National Center for Building Studies and Integrated Research. Simulation results demonstrate favorable conditions for achieving thermal comfort, with elevated air temperatures and velocities at the outlet. Incorporating solar energy considerations into architectural design, such as double facades, south-facing orientations, and glazed surfaces, is crucial. These findings highlight significant energy-saving potential, particularly in the Bechar region.
