TY - JOUR TI - Study on thermodynamic functions of traditional building windows based on characters AU - Hu Yuelian AU - Zhuo Jing JN - Thermal Science PY - 2021 VL - 25 IS - 2 SP - 901 EP - 910 PT - Article AB - The indoor light environment of the building has an extremely important influence on its own use function, and there are many factors that affect the indoor light environment of the building, such as the surrounding environment of the building, the interior decoration of the building, and the design of the window. The window is used as the building envelope. An important part of the structure is responsible for lighting and ventilation meet the requirements of the indoor environment. It exists as a lighting device for the building. The lighting performance of the windows not only meets people’s requirements for living comfort, but also consumes energy in the building. It will have a very important impact. A variety of window shapes start from different functional needs. The comprehensive use of these window shapes by traditional buildings together creates its unique thermodynamic function. This article analyzes cold regions based on the analysis method of thermodynamic functions. Solar heat gain from traditional building windows.
