Special Issue Information

Dear Colleagues,

Indoor Environmental Quality (IEQ) plays an important role in how we feel, work, and stay healthy indoors. This Special Issue focuses on understanding how factors like indoor air quality, temperature, noise, and light affect our health, comfort, and performance. As people spend most of their time indoors, improving IEQ is critical for well-being and productivity.

The aim of this Special Issue is to explore the link between IEQ and outcomes such as physical health (e.g., respiratory issues), mental well-being, and how well people can perform tasks. We welcome studies that assess IEQ, propose solutions for common issues, or introduce new technologies to improve indoor spaces.

This issue is open to research in homes, schools, offices, hospitals, and other indoor settings. Authors can submit original research, case studies, or reviews. We encourage work that connects different fields like health sciences, engineering, and building design to provide practical solutions.

By bringing together a range of studies, this Special Issue hopes to offer new ideas and evidence to improve indoor spaces. The goal is to share knowledge that can help to create healthier and more comfortable environments for everyone.

This study assessed the baseline indoor environmental quality (IEQ) of secondary school classrooms in Tanzania by measuring temperature, relative humidity, noise, lighting, and indoor air quality. Objective measurements were conducted using calibrated sensors in 14 classrooms across five schools, with data collected during occupied school hours and additional noise measurements during unoccupied periods. All classrooms are naturally ventilated through operable windows and doors. The findings reveal a pattern of cumulative IEQ deficiencies: classroom temperatures frequently exceeded the recommended 20–24 °C range, reaching means as high as 30.4 °C, while relative humidity varied widely, with levels occasionally surpassing 65%. Noise levels consistently exceeded the World Health Organization (WHO)’s recommended 35 dBA threshold, with significant differences observed between occupied and unoccupied periods (p = 0.02). Light distribution was uneven, with significantly higher lux levels near windows than at classroom centers (p < 0.001), and artificial lighting was generally insufficient due to infrastructure limitations. Although CO2 concentrations remained below the 1000 ppm threshold, indicating adequate ventilation, particulate matter levels were often elevated, with PM2.5 reaching up to 58.80 µg/m3 and PM10 up to 96.90 µg/m3, exceeding health-based guidelines. Together, these findings suggest that students are exposed to multiple environmental stressors that may impair health, comfort, and academic performance. This study provides a critical baseline for future research and context-specific interventions aimed at improving learning environments in Tanzanian schools and similar settings in East Africa.
