What is the SYNDROME OF Sick Building (SBS)?

Let's immediately clarify our ideas, with the terminology "sick" we don't mean the building, but the people who reside there. The case study reveals that a large number of disorders afflicts individuals who spend many hours indoors.
In recent decades this habit has taken root with the consequence that, while on the one hand the need to have protected environments with acceptable microclimate standards has grown, on the other hand the need to contain energy consumption by eliminating waste and sealing workplaces has increased. 
The sick building syndrome, as found by the OMS itself, manifests itself through a combination of symptoms related to staying in the building itself such as: irritation of the skin and mucous membranes, headaches, mental fatigue, difficulty concentrating. Characteristic of the Sick Building Syndrome (S.B.S.) is that most of the symptoms disappear or fade away away from the "sick building".
The buildings, then, become containers in which the quality of the air is contaminated by countless factors that affect the health of the people who live there.
According to scholars, the best approach for the solution of the disease is the bio-psycho-architectural one, which aims at environmental control, at a conscious design, which puts design and planning to the service of the improvement of the quality of life of those who will have to live in the building.
WELL Bulding STANDARD is the certification that helps to prevent these problems. 
WELL Bulding Standard is the first health and wellness standard to promote health and wellness through the design and construction of buildings. 
WELL measures the attributes of buildings that impact occupants' health by examining seven factors, or concepts: air, water, noise, light, fitness, comfort and mind.
With this approach based on medical research we explore the connection between buildings where we spend more than 90% of our time, and the impacts on health and well-being of us as occupants. 
It is no coincidence that air is the first of the seven concepts on which the Well standard is based, and that the designer of the building must take into account the fact that to optimize and achieve high standards of indoor air quality must consider three aspects: remove contaminants, prevent their appearance and manage purification.
The WELL standard proposes the use of UV-C technology to reduce the microbial load in the air, which would lead to an increase in the IAQ.
