The influence of a classroom’s indoor environment on children’s health, performance and comfort is a concern that receives increasing attention. Many schools experience problems with inadequate indoor air quality and climate. Investigations of the indoor air quality (IAQ) in schools have been often non-systematic, which can lead to costly ad-hoc remediation actions. It is therefore important to develop a holistic approach to the assessment of IAQ in schools.

This paper presents a field study on the indoor air quality and thermal environment conditions of elementary schools in Gothenburg, Sweden. The focus of the paper is on the methodology to investigate the IAQ using both objective measurements and subjective assessment of the perceived IAQ. The indoor environmental measurements include indoor air quality and thermal comfort parameters for which guideline values exist. Finally, a questionnaire was developed to evaluate the perception of the classroom’s thermal environment and air quality by young children.

The paper presents the study protocol and diagnostics approach for IAQ in classrooms. Examples of results from the first 10 investigated classrooms are presented.

教室的室内环境对儿童的健康、表现和舒适度的影响越来越受到关注。许多学校都遇到了室内空气质量和气候不足的问题。对学校室内空气质量 (IAQ) 的调查通常是非系统性的，这可能导致代价高昂的临时补救行动。因此，制定一个整体的方法来评估学校的室内空气质素是很重要的。

本文介绍了瑞典哥德堡小学室内空气质量和热环境条件的实地研究。本文的重点是使用客观测量和感知 IAQ 的主观评估来研究 IAQ 的方法。室内环境测量包括存在指导值的室内空气质量和热舒适参数。最后，开发了一份问卷来评估幼儿对教室热环境和空气质量的看法。
