Scientists University of Nanyan in Singapore (NTU) created window glass, which adapts to weather conditions and saves energy. The study was published in the journal Science.
Glass with a special film reacts to the temperature and the degree of natural lighting on the street and changes its properties. Depending on the situation, the smart window either reduces sunlight into the room, or contributes to the passage of sunlight. Scientists believe that their invention will save resources for heating or cooling at home.
Adaptive window glass is designed using a composite layer, vanadium dioxide nanoparticles, methyl methacrylate and low radiation coat. In the hot time, the glass suppresses light in the near infrared range, at the same time enhanced long-wave infrared radiation, which cools the room. In the cold season, the device concentrates sunlight and sends it to the room. It does not require connection to the electricity.
According to the leading author of the study of Professor Long Yi, the window opening is considered to be less energy efficient part of the house. In American households, energy consumption in buildings associated with windows is approximately four percent of the total consumption of electricity per year.
In late November, scientists of Harvard University described the technology of using live ink during the construction of houses. The material applied by them allows the communication communications to restore independently.
