As an important part of passive ultra-low energy building envelope structure, exterior windows play a very important role in lighting, heat gain, and thermal insulation. Passive doors and windows are currently mostly installed externally, and high installation costs, material costs, and safety have become obstacles in the promotion of energy-saving policies. We calculated and simulated the linear heat transfer coefficient of the window opening based on the software flixopro8, and obtained the window installation position with the smallest linear heat transfer coefficient between the door and window and different wall structures and the decisive factors affecting the linear heat transfer coefficient of the door and window opening.
