are susceptible to exposure of many pollutants from various sources: inert
and biological particles, gas, noise, wave, etc. This contamination can be,
depending on exposure conditions, the occurrence of more or less serious
diseases, such as allergies, respiratory infections and poisoning, etc. In this
context, the management of health quality of enclosed spaces, protection of
health and more comfort to people, is a real challenge.
This process begins with the detection of a substance, particle, wave, on
a level of risk and, then, triggers a proven management process consisting
of implementation and specific actions. These actions may be to remove
the pollutant, inactive it, reduce the risk of infection, for example, contain
the area of pollution, in order to limit the spread or control their sources.
Legionella
The concern with the development of
legionella
appears on target
14, Health Quality of Water. According to assessment scheme of process
AQUA-HQE water quality can be changed in different ways:
• changes on organoleptic properties (odor, color, taste, etc);
• modification of physico-chemical characteristics (temperature,
hardness, concentrations of metals and organic compounds, etc);
• microbiological contamination by bacterial growth or entry of
dirty water.
Thefivemainfactors thatcontributetochangethewater(microbiological
or chemical) on an internal networking of a building are:
• alteration of the materials
• accidental perforations
