decentralized ventilation system / residential
Proper indoor ventilation is fundamental to protect people's good health and to preserve the good status of the building. Insufficient ventilation creates many problems to the occupants (allergies, asthma, headache, exceeded sweating...) which can even become more serious in case of children or old people with breathing difficulties.
The building as well needs to be properly ventilated to prevent the creation of condensation, mold, too high temperature levels which can damage its structure causing unexpected high costs of rehabilitation (Sick Building Sindrome): recently this has become a real topic due to the usage of higher insulation material to increase the tightness of the building, with the consequent elimination of the natural ventilation through window/door openings.
Higher insulation, poor ventilation and increase of the indoor chemical elements lead people to a longer exposure to hazardous composites which can create serious health problems.
