Dr. Ahmed Kazim Al-Shara, a professor in the Department of Mechanical Engineering, and Dr. Qaddama Mohammed Kassem, a lecturer, have successfully published joint scientific research entitled “Advanced Building Envelope by Integrating Phase Change Material into a Double-Pane Window at Various Orientations” in the global journal Energy and Buildings. This prestigious journal has an Impact Factor of 6.6 and a CiteScore of 12.7. It is ranked among the top quarter of journals in both the Scopus and Clarivate global databases.
The research focuses on the thermal improvements of a double-glazed window with variable-phase material (PCM) under hot weather conditions in southern Iraq, specifically in Amarah City. The newly developed window was compared to a reference window with the same dimensions and an air gap. It was experimentally tested in different orientations—East, South, and West—and analyzed through several energy indicators, including the window’s average internal temperature, thermal attenuation coefficient, and temperature delay. The study found significant improvements in the energy efficiency of the window containing PCM across all orientations compared to the reference window. Notably, the internal temperature of the window surface was reduced by up to 23°C, and the heat delay increased by up to 50 minutes.
This research is part of a distinguished project for fourth-year students during the academic year 2023/2024.
The research was conducted with the participation of the following students:
- Mortaza Mahmoud Abdul-lateef
