Experimental Measurement of the CO_2 Content in a Passive Home During a Simulated Air-Conditioning Power Outage

摘要

High concentrations of CO_2 are one of the causes of imperfect oxygenation of the blood circulation in humans. An experimental measurement of a passive home during a simulated power outage was carried out from July 7-15th 2014. In the measured rooms (one with plants with leaves the size of one of the bigger participants in this project, the second room without any plants at all), the levels of CO_2 were observed, as well as the levels of relative air humidity of the interior, and the interior temperature. The measurement was carried out at night, when sleeping time was simulated, i.e. the resting period. The impact of plants did not significantly influence the CO_2 reduction in the interior of the building. Regular airing is necessary for maintaining the hygienic limit of the concentration of CO_2. It is thus necessary to ensure this with the windows open during an unexpected power outage.
