What is the ratio to natural light (KEO)
Title: Lightening
With the help of vision, a person receiving much often from information, and the quality of that on his perception directly depends on clarification. Insufficient lightening can lead to reduced productivity and increased scream. Tova drive to naranyavane or ill on the worker.
When organizing for natural lightening, one of the most important parameters characterizing nivoto for lightness, e KEO is the coefficient for natural lightening. Contrary to strict scrutiny in the regulatory documents and parameters, some owners of the premises will prefer to ignore them. For violations, break it down in time for verification, the owner is paid from punishment.
In this article, I will look in more detail at how KEO is defined, how it affects and where everything is foreseen.
Containment: 1. Definition 2. Formula 3. How do you influence 4. K'deto se vzema foresight 5. Conclusion
Definition
For yes, we will define the parameters, we will define some of the normative and technical documentation. According to the set from the rule SP 23-102-203 and SNiP 23-05-95 (SP 52.13330.2016), the abbreviation KEO means "coefficient for natural lightness".
KEO - the ratio of something to nothing to natural lightening, somehow creating in the room something from natural lightness to a point in the plain, a rock to lightness, created from natural lightness, falling to the top of the horizontal surface from the outside.
Formula
It is calculated on KEO according to the formula:
KEO = (E int / E external) * 100%,
K'deto: Evnutr e indicator for the luminosity in the room, removed from the sun light, lx;
Evneshn e indicator for external lightening, lx.
When determining the cost on KEO, you will be charged foreseeable factors:
- Tip the system for good lighting. You can be natural, artificial or combined.
- Posokat on the light stream e otgor, remove. Such clarification can be combined and yes, including some kind of horn, and such a page of a sap on a light stream.
- The designation for the room is, in some way, distorted the measurement.
What influence
Choveshkoto is healthy, mood and working capacity are directly connected with light. Biorhythmite on the body depends on lightness. The influence on Svetlinat's top is healthy, but it can't be underestimated.
Lipsat on lightlin can have a negative effect on the body on vision, and yes, cause discomfort, migraine and sleeplessness. Tova se reflecting negatively on labor efficiency. It has been proven that during sunny time productivity is usually higher, broken off during cloudy or rainy time.
Prez winter, once in a while, daylight hours for a short time, broken away prez latoto, activity on the servant is painted. These characteristics are related to the production of sensitive camouflage pigments in coveshkit visual organi. Those affect circadian rhythms at the body.
Circadian rhythms will determine the duration of the period for activity and sleep. Hormone affects the top of the promyanat in the biorhythm on the body: cortisol is dissuaded for activity, melatonin is dissuaded for sleeping, the production of dopamine affects mood, etc.

The number of things on the tezi hormoni without leaving a prez whole den. To this one, change it, and to the other, take it to the change in biological rhythms for the whole organism. Circadian rhythm depends on the natural flow in biological rhythms, and from it on your own and indicators for working capacity, physical, mental activity and energy.
K'deto se vzema foresight
KEO is foreseen when designing a system for natural lightening. Orientation to the gradation in space, then, size to see open, the need for additional artificial clarification directly depends on the tosi coefficient.
Figure 2. Orientation to the grade of cardinal points
When counting on KEO, everything is expected to cause, affecting the top of the result. Those include the distribution of the armor on the group zone on the administrative districts, which will take into account the specifics on the bright climate, and on the natural light intensity directly depends on the armor on the sunny days of the year and on the stability of the snowy slope, and somehow on the complexity of the visual work, location on the light, open up the cardinal points and others like that.
In rooms where a significant amount of wind is more likely to remain for a long time, for example, in hospitals, clinics, educational institutions, office premises, children's gardens, the presence of such a skylight is not required.
The coefficient for natural lightness is determined with the help of a special device - luxmetry. Use two lux meters at a time for accuracy. In tozi case, the worker of the right to measure, dokato e in flocks, and vtoriyat - navn.
Figure 3. Light meter
Illumination is measured by itself in determining the point, is selected, foreseeing it all in the earth, possibly sensing from the darvet, cleanliness is open on the aperture, in places, free from furniture or equipment.
Conclusion
Inadequate lightening reduces performance and increases the risk of injury and chronic disease. The need to use additional artificial lighting when designing or reconstructing fences and premises depends on the rules for assessing the coefficient for natural lighting.
