Research has shown that underventilation of buildings is common and negatively impacts occupant’s health and productivity.

• A 2016 study in an environmentally controlled office space examined the effect of air quality on cognitive function. Participants were found to have higher cognitive function when their indoor environment had higher ventilation rates, lower volatile organic compounds, and lower carbon dioxide.
• A 2003 report by Fisk found a majority of existing literature indicated increasing ventilation will decrease respiratory illness and associated sick leave.
• A 2012 study showed a decrease most decision making variables increases in indoor carbon dioxide concentrations.
