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 concentration in educational buildings has been identified as a significant issue affecting students’ performance. This study measures and addresses how serious the CO2 levels are in differing educational facilities in north-east China during the winter period when windows have remained typically always closed to minimise heat loss. The research is based on indoor air quality measurement with the CO2 and temperature & humidity data log, and also the users’ experience. The negative impacts of CO2 concentration are demonstrated to affect students’ decision-making capabilities, and the relevant Chinese building regulations related to the requirements of indoor air exchange have also been reviewed. The paper also proffers practical solutions from architects’ point of views to improve indoor air quality, specifically related to CO2 concentration in educational buildings. A brief comparison of the indoor air quality with a specific focus of CO2 concentration in educational buildings in China, and other countries around the world based on literature has been addressed. This intends to highlight the severe situations in Chinese education buildings.
