| Abstract | Sleep quality can affect human health and the next-day performance. High indoor CO2 concentrationlevels due to insufficient supplied air ventilation could cause poor sleep quality. Bedrooms in condominium inThailand commonly use a wall mounted split type system without supplied outdoor air ventilation. The roomsare typically constructed having airtight envelope which have air infiltration rates ranging 0.4-0.64 ACH. Thisstudy aims to evaluate the impact of increased ventilation rates on sleep quality and the next-day performance,which the surveys were collected from two occupants living in a one bedroom condominium. The fieldmeasurement and survey were conducted for twenty days with supplied outdoor airflow rates at 0, 40, and 60m3 hr-1 through an energy recovery ventilator (ERV). The room air exchange rates were calculated from a linearregression method obtained from a decay tracer gas technique using indoor carbon dioxide generated byoccupants. To overcome the maximum limit of CO2 concentration level specified in the standard health guidelines,the ERV unit has to supply outdoor air ventilation rate at 60 m3 hr-1. Overall, the increase of outdoor airventilation rates can improve sleep quality by 2-13 percent and occupants have better work performance inthe next day by 2-20 percent. The increase of outdoor air ventilation through the ERV unit does not affectindoor relative humidity. |
