Abstract
Despite people spending approximately one-third of their lives asleep, bedroom ventilation in New Zealand homes remains poorly characterised. Existing research is limited to one small study (seven households with two bedrooms monitored per household, n=14) that reported bedroom CO2 concentrations of up to 4,000ppm. Therefore, this pilot study aimed to contribute to the evidence base by measuring and evaluating bedroom CO2 concentrations in a sample of Wellington households.
