Abstract


Indoor air quality is a major contributor to the quality of people’s lives. Notwithstanding pollutants that are becoming increasingly prevalent from new building materials, furnishings and consumer products, CO2 density in educational buildings has been identified as a significant issue affecting students’ performance. This paper presents the results of monitored CO2 levels in differing educational facilities in north-east China during the winter period when windows have remained typically always closed to minimise heat loss. The negative impacts of CO2 density is demonstrated to affect students’ decision-making capabilities, and also the relevant Chinese building regulations related to the requirements of indoor air exchange have been reviewed. Finally, this research proffers practical solutions to improve indoor air quality, specifically related to CO2 density in educational buildings.
