In the frame of the project Flux50 smart ventilation, researchers and industrials aim at qualifying ventilation in mid-sized buildings through multidisciplinary consideration of sleep quality, user satisfaction, acoustic comfort, installation, maintenance, resilience and indoor air quality. As those factors may impact at different levels it is important to select a common metric for evaluation. Assessment of financial costs induced by the various categories will be used in that purpose.

Our bodies need good rest and sleep as part of regular recuperation to enable us to perform our normal activities in life. Sleep is an integral part of human life and the importance and significance of good bedroom IAQ, indoor air pollution, ventilation as well as bedroom thermal environment during sleep cannot be emphasized more. Yet, there is a paucity of information in the scientific literature in this regard, especially pertaining to IAQ in sleeping environments and sleep quality. Are our bedrooms adequately ventilated at all times to maintain good IAQ?

The association between indoor air quality (IAQ) and sleep quality was investigated in this study. A total of 27 participants (14 males and 13 females, 20-33 yrs.) without any sleep disorders and chronic diseases were recruited and divided into two groups: a polysomnography (PSG) group and a non-PSG group. The IAQ was changed by opening or closing windows. There were two phases for the experiment and two nights in each phase including one adaptive night and one test night, and around one-week washout period between two phases.

More than 20 years of one’s life is spent in the bedroom when sleeping. Sleep quality is essential for our health, well-being and next-day performance. However, there is very little information on how bedroom air quality affects the quality of sleep. One of the reason could be that the accurate measurements of the quality of sleep have been the domain of sleep research groups and sleep laboratories using polysomnography. In the recent years, however, many low-cost sleep monitors and actigraphs made their way into the market.

At typical indoor CO2 levels there is no scientific evidence that CO2 is harmful to comfort and health of healthy persons, though there is a potential for negative effects on some aspects of performance. Research also indicates that insufficient bedroom ventilation may negatively affect the quality of sleep.
