Study on Indoor Air Quality in the Education Building Teaching Space

Maintaining good indoor air quality (IAQ) aimed at meeting human requirements on health and comfort of a space. This study takes the IAQ of the construction square of Xi’an University of Architecture and Technology before winter heating as an example. Four basic parameters: indoor air temperature, CO2 concentration, relative humidity and wind speed were tested to evaluate the basic condition of IAQ in the construction square. Through the analysis of the basic parameters of indoor air changes with time and the influence to the human body, this study will point out the existing problems in this space and give some improving suggestions.
