Four Elements of Sick Building Syndrome

There are four elements of sick building syndrome in general  

These four elements may act in combination, and may supplement other complaints such as inadequate temperature, humidity, or lighting. 

There are studies to model the sick building syndrome in residential interiors depicting the relationship between common health problems and factors leading to sick building syndrome [6]. 

There are studies to suggest safer construction materials with the lowest possible risk on health for the indoor environment, mainly to decrease the effect of second factor (chemical contaminants from indoor sources) listed above [7, 8]. Most of these are natural , or in other words, they are green . However, one should also consider the fact that, all natural things are not safe. A number of natural materials can contain VOC and hence can pose hazards to health as well. Radon is an example, it is a natural material, which is radioactive and exists almost everjrwhere in the house. In addition, allergic reactions to the odours from cedar furniture, a natural material, are very common. The risk is always low if a certain agent remains in the building product that does not affect occupants through respiration and physical contact. 

Less toxic (natural or synthetic) alternative materials should be used whenever possible, and if this is not possible, than products that off-gas a little should always be used in preference to those that off-gas a lot.
