Traditional building-integrated solar thermal systems (BIST) often face challenges such as high costs, design constraints, and glare, which limit their widespread adoption. To address these issues, this study proposes a novel building-integrated solar thermal system called the Black Wall (BW), which enhances energy efficiency by utilizing capillary tubes without glass covers. Since existing energy simulation programs, such as EnergyPlus and TRNSYS, do not offer models suitable for analyzing the BW system, it was necessary to develop a refined model. A mathematical model, based on RC networks and the fin method, was created to simulate the thermal performance of the BW system. The simulation model was validated by comparing its results with experimental data collected from a test installation. The validation results showed a normalized root mean square error (nRMSE) of 11%, indicating a high level of accuracy in the simulation model. The BW system achieved approximately 40% heat gain efficiency, comparable to GLST systems, while offering advantages in design flexibility and ease of installation. This research demonstrates the potential of the BW system as a viable solar thermal collector, with future studies focusing on its integration with heating systems.
