We all think that in the middle of summer, we should open the doors and windows to cool down, but in fact, it is not. During the day, the indoor and outdoor air temperature is high, the doors and windows are opened, and the sunlight and heat radiation come to the room with gusts of hot air, which will make the indoor and outdoor become generally hot. If you open the doors and windows to ventilate when it is cool in the morning and evening, let the air circulate, and close the doors and windows in the daytime, especially at noon, to isolate the invasion of outdoor hot air, and pull the light colored curtain to block the sunlight, reflect the heat radiation, you can make the room more cool.

Windows: ventilation, daylighting (the role of viewing) - size, form, opening, structure.
Doors and windows can be divided into enclosure components or partition components according to their positions. There are different design requirements, which should have the functions of heat preservation, heat insulation, sound insulation, waterproof and fire prevention. The new requirements are energy saving. The heat loss caused by the gap between doors and windows in cold areas accounts for about 25% of the total heating consumption. The requirement of airtightness of doors and windows is an important content in energy-saving design. Doors and windows are important components of building envelope system.
Doors and windows are an important part of architectural modeling (virtual reality contrast, rhythmic art effect, plays an important role), so their shape, size, proportion, arrangement, color, shape and so on have a great impact on the overall shape of the building.
Now many people install double glass doors and windows, in addition to enhancing the effect of thermal insulation, the very important role is sound insulation, the city is prosperous, residential density, traffic is developed, the sound insulation effect is more and more popular.
About casement windows:
The advantages of casement windows are large opening area, good ventilation, good sealing, sound insulation, heat preservation and impermeability. It is not convenient to open the window inside or outside. The disadvantage is that the window width is small and the vision is not wide. The opening of the external window needs to occupy a space outside the wall, which is easy to be damaged when the wind blows; and the inner window is to occupy part of the indoor space, so it is not convenient to use the screen window, curtain, etc. when opening the window, it is not convenient to use the screen window and curtain.

That is to say, the window can be opened a little from the top. The open part is suspended in the air, and is connected with the window frame through hinges, etc., so it is called up hanging type. Its advantages are: both ventilation and safety can be guaranteed, because there are hinges, the window can only open 10 cm of the seam, from the outside hand can not come in, especially suitable for use when there is no one at home. This function is not only limited to casement windows, sliding windows can also be suspended open.

Balcony courtyard greening, planting trees and flowers, not only has a high ornamental value, but also has the role of regulating the microclimate, will make the air fresh, cool and pleasant. Because green plants can not only shade the sun, but also reduce the temperature by evaporating water from the leaves. Some data show that planting some flowers and plants on the balcony of courtyard can reduce the indoor temperature by 2 ℃～ 4 ℃.
After wiping the floor with a wet mop, open the ceiling fan to make the ground water evaporate and absorb heat; you can also put a basin of cold water in front of the fan, and turn on the fan to make the water evaporate to cool air. This can reduce the room temperature.
