CO2 doesn't have exactly the same marriage with pollutants from non-human sources that it does with human emissions. Off-gassing from developing materials, furnishings, cooking, cleansing and electrical merchandise could be unbiased of occupancy [30] e.g., Offermann located small CO2 stages at the side of dangerously significant levels of formaldehydes [31]. Nonetheless the place you'll find reduced ventilation costs you'll find somewhat larger pollutant concentrations from both human and non-human resources, and so using CO2 as a proxy for ventilation rate in cases where occupancy is thought can be a justifiable method.
The Central Tower from the Palace of Westminster. This octagonal spire was for ventilation purposes, in the more complicated process imposed by Reid on Barry, through which it was to attract air out of the Palace.
