Description

technical field [0001] The invention relates to a method for optimizing geometric parameters of exterior windows of office buildings in severe cold regions. It specifically relates to a method for optimizing the geometric parameters of exterior windows of office buildings in severe cold regions based on the consideration of heating energy consumption. Background technique [0002] With the economic development of cities in cold regions, the area of ​​office buildings in severe cold regions continues to grow. In severe cold areas, the indoor and outdoor temperature difference is huge in winter, and heating energy consumption accounts for a relatively high proportion of total energy consumption. On the one hand, due to the high heat transfer coefficient of glass material, the main component of the building's exterior windows, the heat lost through the building's exterior windows is much higher than the heat lost through the building's exterior walls, making the building's ext...

Problems solved by technology

[0003] In the design of the geometric parameters of the exterior windows of traditional office buildings in cold regions, the designers usually reduce the building window size to reduce the heating energy consumption. Increasing, but blindly reducing the size of external windows will not only affect the natural lighting effect inside the building, increase the energy consumption of artificial lighting, but also lead to a decrease in the solar radiant heat obtained by the building during the day, resulting in an increase in building heating energy consumption
