Keeping a pristine HVAC system and evaporator coil has done wonders in improving hospital IAQ and improving energy savings.
In the past twenty years, a growing body of scientific evidence has indicated that the air within buildings and homes can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. Other research indicates that people spend approximately 90 percent of their time indoors. Thus, for many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors.

Another death has been attributed to the largest Legionnaires' outbreak in Ohio history this morning and health officials said they have concluded water tests and found the source of infection.
The outbreak, which as of today has killed five and sickened 35, was caused by the potable water and air-conditioning cooling tower at Wesley Ridge Retirement Community in Reynoldsburg, said Franklin County Public Health spokeswoman Mitzi Kline.
Kline said the retirement community has gone "above and beyond" in taking precautions to protect its residents, staff and visitors.

High levels of the bacteria Legionella were found at a Carnegie Mellon University cooling tower, prompting a warning to students and staff from the university on July 23.
Legionella can cause Legionella disease, but CMU Spokesman Ken Walters said no cases have been identified. The campus community was notified of the finding as a "purely precautionary measure," he said Friday.
The tower has been treated to kill the bacteria and...
Toronto Public Health says it has seen more cases of Legionnaires' disease than it would expect at this point in the summer and it is advising physicians to be on the lookout for additional cases.
Dr. Rita Shahin, one of the city's associate medical officers of health, said Tuesday that officials have become aware of 16 cases in a six-week period. That's well above the three or four cases that officials would usually expect to see.
Indoor air quality (IAQ) is probably the most commonly discussed aspect of building indoor environmental quality (IEQ). IAQ has direct effects on our health as well as the perception of an acceptable indoor environment. In the United States, ASHRAE Standard 62.1: Ventilation for Acceptable Indoor Air Quality is the most commonly referenced standard to quantify acceptable conditions and appropriate HVAC system design.
