Sunlight is extremely necessary not only plants that die without it very quickly.People are a little bit less dependent on the light, but not too long survive without sunlight.Of course, you can live and electric light, but a variety of diseases will be your companions throughout life.No wonder many decades, consumption was considered an incurable disease - it provoked living conditions in areas with insufficient lighting, which flowed much of a person's life.
Why do we need light
consumption (aka TB) - is not the only disease that threatens human lack of light.The list of diseases that are beginning to "blossom" with the lack of sun, are: rickets - is especially dangerous for young children;scurvy - a forgotten disease, which is caused not only by a lack of vitamins, but also the lack of lighting;osteoporosis - for new medical data also provoke life-giving sunlight deficiency.What can I say, even diabetes occurs in a mild form, if a person lives in normal lighting conditions.So we can say that the insolation - is the key to the survival of humanity.And if you're going to buy a house, ask first of all, whether well lit your future apartment.
Justification requirements for the quantity and quality of light
We will understand the terms.Insolation - is the degree of illumination of any room during the day.And do not think that the more sun - the steeper and wonderful.Those who have an apartment facing south, fenced off from the searing summer and glare variety of methods.Excess light just as harmful as the lack of it.Insolation - this is just an exact calculation, balancing between the two extremes still unprofitable.
Regulatory calculation of insolation is always dependent on geography.If you focus on the 55 degrees north latitude, the focus for vyschityvaniya on what is needed insolation of buildings, given the time, starting from March 22 and ending on September 22.In other latitudes, a vital period of coverage, of course, is shifted.
There is another factor that affects the insolation.This bedroom apartments.If the number of rooms - up to three, then at least one of them should be covered;if four or more - must be covered at least two.
duration lighting
This issue has been resolved and recorded in the 60 years of the twentieth century.Strongly determined that to preserve the health of people living in the apartment, a couple of hours a day a house should be well lit by the sun.If the sun "guests" in the room for longer - that's a plus, but its excess, as already mentioned, is not a helpful factor.Even a three-hour intensive coverage actually stimulates the explosion-breeding of germs and bacteria - and most of them are pathogenic.So planners are trying to expand the building, so that strictly to the south windows of the houses did not go.Frankly, insolation residential buildings - a science.
Special cases
northern and central areas have some easing of norms of insolation - it can be reduced to 10 minutes, if the apartment is covered at least two rooms.
If we consider a multi-storey building (skyscraper over 9 floors), as well as areas of the city, where there is overcrowding of houses and dense buildings area insolation buildings also undergoing some changes.First of all, allowed discontinuity insolation, in some cases it may be repeated.However, while the total Insolation time should be extended by half an hour.
pay attention to the details of construction, where there may be "easing" Insolation regime.The main and most defensible case - the so-called meridional buildings, which cover almost all the rooms.Naturally, norms of insolation are respected in any case.The second option - the reconstruction.If a person wants to limit yourself to light and thus does not violate the rights of its neighbors - is a private matter, he wants to risk the health, even at risk.But a third option ...
Violation
There is a very imprecise formulation, which is unlikely to explain even the most experienced lawyers.It sounds like a "particularly complex urban conditions."The exact definition of "complexity" does not exist, but under it can be attributed to anything.It is this point are unscrupulous officials and entrepreneurs who are building a shopping center that looks into the window of an apartment house.If you do not want to - leave it at that.But remember: insolation premises - this is very significant, the lack of light and has a bad effect on the physical and mental health.Especially clearly this is manifested in children and the elderly.Do not want to treat their children, or ahead of time to bury their ancestors (and fight the ills that have overtaken soon) - insist on their right to have a vital "breath of" light.
