Energy-saving Electrochromic Installed in Japan in “Kudan Kaikan Terrace”
NSG Group announces that the energy-saving electrochromic (dynamic light control) window "View Smart Glass" was adopted for the first case in the new "Kudan Kaikan Terrace" (Chiyoda-ku, Tokyo) in Japan. This new office building opened on 1 October 2022.
What is "View Smart Glass"?
The smart electrochromic (dynamic light control) glass “View Smart Glass” developed by the US based company View, Inc. changes the tint of the electrochromic film, which is composed of a transparent conductive metal coated on the glass surface, by applying controlled voltage. It can change the transmittance of visible light, UV rays, and solar radiation. The tint can be adjusted in four stages suppressing the light transmittance to a minimum of 1% without using any blinds or sunshades. To date, many facilities such as offices, schools, airports, and hotels in the United States and other countries have installed the windows.
At the Kudan Kaikan Terrace, which was one of the first office buildings in Japan to utilize View Smart Glass, the incorporated IGU is installed on the office entrance, the plaza as a node to each area, and the first floor. Using data from multiple sources, including sensors installed on the roof of the building, artificial intelligence automatically determines how much to adjust the transmittance of the glass, optimizing the amount of natural light and heat entering the room throughout the day. While ensuring a beautiful view of the Palace Gardens without any restrictions, it is possible to reduce energy consumption for air conditioning and lighting.
