In 2004, the Regulatory Memo of the General Directorate of Health was
deployed. Its aimwas to guide state bound facilities on how to study and treat

water used in spas (determination 1220/2000 of 29 December). Services of
Public Health, however, had distributing guidelines at a regional level.
In April of 2006, the detection of this pathogen in water was legislated with
the LawDecree - 79/2006, of April 4, on Regulation of Climate Energy Systems
in Buildings (RSECE): “In aerosol producing systems in buildings, particularly
cooling towers or humidifiers running on liquid water or hot water shower
systems with temperatures below 60 °C, IAQ audits include the detection of
Legionella
in
water samples
collected in high-risk locations - especially on
tanks of cooling towers, hot water tanks and condensation trays. The

In January of 2014, the Law Decree - 79/2006, of April 4 was revoked by
Law Decree - No. 118/2013, of August 20, and aims to ensure and promote
the improvement of energy performance of buildings through the System
Energy in Buildings (SCE) certification. SCE integrates the Regulation of
