Healthy Indoors



Air quality and your productivity and health

With people spending about 90% of their lives indoors, buildings have a substantial impact on the health and well-being of their occupants.

Air quality and your productivity and health

The graph above offers some examples of how factors such as temperature and relative humidity, both important components in the air we breathe, affect us. At a temperature of over 21° C indoors, performance drops rapidly. At CO2 levels that exceed 1000 PPM (limit value for a healthy environment), we know that our ability to think strategically drops drastically. Beyond that, there is an association between airborne particles and illness, especially small particles against which the human body has no natural defense.

The WELL Building Standard argues that well-ventilated offices can double the cognitive ability of workers. Upon examining the effect of thermal comfort, it concluded that performance drops by 6% if office space is too hot and 4% if it is too cold. Moreover, studies have found that high levels of carbon dioxide (CO2) significantly diminish cognitive ability and strategic thinking.
