Instead of setting throughput at a fixed air replacement rate, carbon dioxide sensors are used to control the rate dynamically, based on the emissions of actual building occupants. Given the well established roles of oxygen sensing pathways in cancer and the acidosis independent role of carbon dioxide in modulating immune and inflammation linking pathways, it has been suggested that the effects of long-term indoor inspired elevated carbon dioxide levels on the modulation of carcinogenesis be investigated.[33].

Pollution is caused by both biomass and fossil fuels of various types, but some forms of fuels are more harmful than others. In halls, gym, dining, and physiotherapy spaces, the ventilation should be sufficient to limit carbon dioxide to 1,500 ppm. In many cases, if materials have failed to dry out several days after the suspected water event, mold growth is suspected within wall cavities even if it is not immediately visible. | These biological chemicals can arise from a host of means, but there are two common classes: (a) moisture induced growth of mold colonies and (b) natural substances released into the air such as animal dander and plant pollen. Cooking fuels are coal, wood, animal dung, and crop residues.[11].
