Abstract

Indoor air quality (IAQ) plays an important role in human health as people spend the majority of their time indoors. A self-reporting application was developed to collect long-term perceived IAQ data and symptoms caused by poor IAQ immediately at the onset of symptoms. The feasibility of the application was tested in a real-world environment by four teachers in two school buildings for 18 weeks. The participants received two questionnaire notifications per day to answer IAQ, symptoms, productivity, stress, sleep, and pupil concentration/restlessness related questions. They were also able to report those issues any other time. During the pilot, the participants answered 569 questionnaires in the application. They found the application to be usable and useful, however, the frequency of questionnaire notifications became heavy, because the perceived IAQ did not change much. The feasibility study showed the potential of the self-reporting application to capture perceived IAQ and symptoms, promptly enabling fast reaction to possible problems in IAQ.

Highlights

  • The World Health Organization (WHO) has recognized various problems in indoor air quality (IAQ) as major risk factors for human health [1]

  • The self-reporting application was in use the entire time and this paper focuses on the evaluation of its feasibility, a description of the whole pilot is given to understand the context of use

  • net promoter score (NPS) was formed based on the percentage of promoters minus the percentage of detractors scale ranging from

Summary

Introduction

The World Health Organization (WHO) has recognized various problems in indoor air quality (IAQ) as major risk factors for human health [1]. Knowing the fact that people spend most of their time indoors 90%) and children spend a large portion of it at school, indoor environments should support health and promote learning [1,2]. Poor IAQ is shown to be associated with several adverse health effects, such as allergic reactions, asthma, or neurological symptoms [3]. The likelihood of the effects caused by the contaminants in the air depends on the individual’s sensitivity, contaminant concentration, and the duration and frequency of exposure, actual exposures are often difficult to quantify [4]. The current state of the individual’s psychological and physical health affect the response to poor IAQ
