Keo

Keo (from the English KEO - natural light factor) is an indicator that reflects the amount of light entering the room through windows and other light openings. It is one of the main parameters that determine the comfort and safety of people staying in a room.

KEO is measured as a percentage and shows how much natural light enters the room. The higher the keo, the better the illumination of the room. However, too high a keo can lead to overheating of the room and increased energy costs.

To calculate the KEO, you need to know the area of ​​the room and the number of windows. Typically, KEO calculations are carried out when designing buildings and premises, but may also be required when renovating or modernizing existing buildings.

When calculating KEO, various factors are taken into account, such as the shape and size of windows, the distance between windows and walls, the presence of curtains or blinds, etc. It is also necessary to take into account the climatic conditions of the region where the building is located.

Depending on the type of room, keo may be different. For example, for residential premises it is recommended that the KEO is at least 2%, and for office premises - at least 3%. However, in some cases, for example, for industrial premises, keo can reach 10% or more.

In addition, keo also affects the health of humans and animals. Lack of light can lead to sleep disturbances, decreased immunity and other health problems. Therefore, when designing and constructing buildings, it is necessary to take into account not only economic aspects, but also human health.

Thus, keo is an important parameter for determining the comfort and safety of people staying in premises. KEO calculations should be carried out when designing buildings, repairing and modernizing existing premises, as well as when developing new technologies and materials for construction.
