In the summer of 2015, a legionellosis outbreak attributed to Legionella bacteria exposure from a contaminated cooling tower caused 16 deaths in the South Bronx.

The Use of Tracer Gases in Measuring Ventilation Rates
Often, ventilation rates in residences, offices or commercial establishments must be determined. If ventilation rates are too low, complaints about indoor air quality may arise. If ventilation rates are too great, heating and cooling costs may rise. Ventilation can be controlled by using heating ventilation and air condition (HVAC) equipment that allows fresh outside air into occupied spaces after being adequately conditioned.
