For the efficient energy control of CO 2 intruding a building from ambient air, the rise of atmospheric CO 2 concentration needs to be urgently suppressed.Ĭarbon dioxide Indoor air Low-level exposure Physiological change Psychomotor performance.Ĭopyright © 2018 Elsevier Ltd. In the context of significant linear increase of globally ambient CO 2 concentration caused by anthropogenic activities and sources, reducing indoor CO 2 levels by ventilation with ambient air represents an increase in energy consumption in an air-conditioned building. However, other indoor comorbid pollutants are possibly involved in such effects. Respiratory symptoms have been indicated in children exposed to indoor CO 2 concentrations higher than 1000 ppm. Numerous epidemiological studies indicate an association between low-level exposure to CO 2 beginning at 700 ppm and building-related symptoms. Further research on the long-term effects of low-level CO 2 exposure on the autonomic system is required. Changes in autonomic systems due to low-level exposure to CO 2 may involve these effects. Human experimental studies have suggested that short-term CO 2 exposure beginning at 1000 ppm affects cognitive performances including decision making and problem resolution. Linear physiological changes in circulatory, cardiovascular, and autonomic systems on exposure to CO 2 at concentrations ranging from 500 to 5000 ppm were evident. Electronic address: literature and documents pertaining to the effects of inhalation exposure to carbon dioxide (CO 2) on human health and psychomotor performance were reviewed.
