What causes the Sick Building Syndrome

Low energy consumption, high living comfort

One of the main causes of indoor pollution is that buildings are overly insulated and airtight which stops them from breathing.

Energy-saving legislation passed recently requires buildings to be fully insulated and draught-proofed in order to save energy and reduce the amount of energy needed for heating.

This has severely limited the natural circulation of fresh air, commonly referred to as the building’s natural ventilation, which in turn adversely affects the quality of indoor air, leading to the Sick Building Syndrome. According to the US Environmental Protection Agency, using natural and/or forced ventilation to reduce the concentration of pollutants in indoor air (by diluting them) seems to be the most feasible solution at present. When contemplating the design of a building, creating natural ventilation has to be a priority in order to improve the internal microclimate; this can be achieved by selecting appropriate building materials which must be highly porous, hygroscopic and breathable.

The Kerakoll GreenBuilding systems allow the saving of energy to protect the environment and improve the energy and environmental performance of buildings and at the same time permit the house to breathe by applying natural insulating cladding or breathable insulating plasters that ensure optimum heat insulation while maintaining breathability in the walls, benefiting wellbeing inside the buildings and making them less costly to heat and cool, healthier, and more eco-friendly.

Breathable systems for insulation and energy saving were subjected to severe performance tests in a special thermal chamber that is on the cutting-edge of technology in Europe, developed in collaboration with the University of Modena, Civil Engineering Department and approved by the ITC Institute – Institute for Construction Technologies – CNR – Milan.
