Indoor Air Quality

In 1984, the World Health Organization released a report finding that many newly constructed office buildings had flaws in their heating, ventilation, and air conditioning (HVAC) systems. These defects affected indoor air quality so severely that they caused conditions such as headaches, nausea, and fatigue, among others, in workers.

Many of the office buildings in the study still stand, with the same ventilation problems they had 30 years ago. Newer buildings are being designed with better ventilation, but until their designs become the norm it’s probable that health issues related to indoor air quality will continue.
