Legionellosis often represents a not considered risk in biological risk evaluation of schools, but epidemics have been discovered in environments like schools, hotels and hospitals
Security measures has been immediate for the infected rooms. These measures have been activated by a major's decree to debilitate the dangerous bacterium
Studies carried out by authoritative American associations (NADCA National Air Duct Cleaners Association, ASHRAE American Society of Heating, Refrigerating and Air Conditioning Engineers) have shown that preventive hygienic maintenance (like cleaning batteries and particulate removal, restoration of components of Air Treatment Units and removing any blockages in the ducts) improve the performance of the systems, reduce energy consumption and therefore lower environmental impact and produce considerable savings.
Preventive action and good maintenance practices significantly increase energy efficiency and the performance of aeraulic systems in buildings and can reduce energy consumption on average from 5 to 12 % depending on efficiency of the same.
Seeing as the cost of guaranteeing health and safety is offset with time in light of the resulting energy saving it can therefore be considered an investment not a cost.
Limiting energy consumption on a par with performance means achieving a long term saving respects nature and preserves the energy resources of our planet.
