The building industry accounts for almost 40% of the world's energy consumption. To reduce the global heat transfer coefficient, sustainable buildings should use highly insulated enclosures. As the building envelope serves as a barrier between the exterior and interior of the building, integration of passive solar design principles in its construction, such as smart windows with low thermal conductivity materials are essential. Smart windows may assist to reduce energy consumption by minimizing heat gain by the building, which able reduce the cooling loads while maintaining the thermal comfort for the building users. This study features smart double-glazed windows filled with low thermal conductive materials which are argon and aerogel to improve window insulation in pursuit of energy efficiency improvement. A numerical model is developed in ANSYS Workbench to evaluate thermal insulation performance of argon-filled and aerogel-filled windows by measuring the indoor surface temperature of the building at three critical times of the day. Newton's Law of Cooling is used to compute the empirical value of the heat transfer across the window to compare and validate the numerical data. This study shows that argon-filled and aerogel-filled window able to reduce the heat transfer across the building up 21% and 59% respectively. Aerogel is proven to resist more heat transfer as compared to argon

“…Gambar 4 juga memperlihatkan bahwa daya listrik meningkat dengan meningkatnya radiasi matahari. Selain itu, peningkatan maksimum daya sel surya dengan sistem pendingin adalah 16% lebih besar dari yang tidak didinginkan [25]. Pada kejadian penyinaran matahari 1500 W/m 2 , daya listrik sel surya yang dikopel dengan peredam panas yang didinginkan dengan sistem pendingin alami adalah 1,86 W dan untuk sistem sel surya yang didinginkan dengan udara paksa adalah 2,04 W.

Dalam studi ini, kami menyaajikan investigasi eksperimental terhadap kinerja sel surya yang digabungkan dengan peredam panas. Pengaturan eksperimental dalam ruangan dirancang dan dirakit untuk menyelidiki dampak penggunaan sistem pendingin peredam panas pada kinerja sel surya. Lampu halogen digunakan untuk mensimulasikan radiasi matahari dan penelitian dilakukan pada nilai radiasi matahari yang berbeda. Selain itu, penelitian dilakukan pada udara alami dan paksa untuk mendinginkan peredam panas. Hasil penelitian menunjukkan bahwa penggunaan sistem pendingin peredam panas meningkatkan kinerja sel surya. Suhu sel surya menurun sekitar 5,4 % dan 11 % masing-masing dengan menggunakan sistem pendingin peredam panas pada udara alami dan udara paksa di atas peredam panas. Selain itu, efisiensi dan daya sistem sel surya meningkat sekitar 16% saat sistem pendingin peredam panas digunakan.In this study, we conducted an experimental investigation of the performance of a solar cell coupled with a heat sink in a relatively simple system. An indoor experimental setup was designed and assembled to investigate the impact of using a heat sink cooling system on the performance of solar cell performance. Halogen lamps are used to simulate solar radiation and research is carried out on the value of solar radiation which varies from the highest wavelength to the lowest wavelength. In addition, research was carried out on natural and forced air to cool the heat sink. The results showed that the use of a heat dissipation cooling system increases the performance of solar cells. The temperature of the solar cell was decreased by about 5.4 % and 11 % respectively by using natural air and forced air to overheat sink cooling systems. We believe the efficiency and power of the solar cell system increase by about 16% when a heat dissipation cooling system is used.
