One of the problems that arise when trying to block the heat from the sun is that the view to see out the window is also blocked. Researchers from Nanyang Technology University (NTU), Singapore, managed to find a solution to solve this problem. The solution is electrochromics smart windows. To discuss the details of this invention, the Environmental Engineering Study Program, President University (PresUniv), presented Ronn Goei, Ph.D., a senior research fellow from NTU, to be a guest lecturer in a guest lecture entitled High Performance Electrochromics Smart Windows: Energy Savings for Green Building, Thursday (2/12). Ronn is one of the researchers who participated in that project.
This online guest lecture was guided by Rijal Hakiki, ST, MT, a lecturer in Environmental Engineering Study Program, PresUniv. Also present were Ir. Temmy Wikaningrum, M.Sc. Head of Environmental Engineering Study Program, PresUniv. Ronn explained, electrochromic smart window is a special nanostructure-coated glass panel to block infrared radiation. According to him, indoor lights and air conditioners (AC) account for about one third of electricity consumption in residential and commercial buildings. Thus, the installation of electrochromic smart windows on the building facade would promote overall energy savings and ultimately reduce energy cost building usage.
Ronn also revealed, “Electrochromic smart window is 30% more effective in regulating heat than current ones while being cheaper to make. When used in buildings, this invention may help conserve energy that would be used for heating and cooling.” When switched on lab tests, said Ronn, electrochomics smart windows block up to 70% of heat while allowing up to 90% of light to pass, so the view remains clear. Ronn continued, “This electrochromic smart window has high visible light transmission, high NIR contrast, high coloration efficiency, fast switching time, and excellent stability.” (Gilang Suryanata, PR team.
