Summary
Classroom microclimate conditions in Messina primary schools often fail to meet Italian standards. Objective thermal comfort indices (PMV and PPD) indicated discomfort, contradicting students
Area of Science:
- Environmental Science
- Building Physics
- Indoor Air Quality
Context:
- Research conducted in 18 primary school classrooms in Messina during winter and spring.
- Focus on microclimatic parameters (temperature, humidity) and lighting conditions.
- Assessment of indoor environmental quality in educational settings.
Purpose:
- To evaluate microclimatic parameters and lighting in primary school classrooms.
- To assess thermal comfort using objective indices (PMV, PPD) and subjective questionnaires.
- To investigate the discrepancy between instrumental thermal comfort indices and student perceptions.
Summary:
- Many classrooms exhibited temperature and relative humidity levels non-compliant with Italian standards.
- Thermal indices (PMV and PPD) revealed widespread thermal discomfort, with high percentages of dissatisfied individuals (56.8% in winter, 70.3% in spring).
- Student-reported thermal sensations frequently differed from Fanger's predicted comfort indices, suggesting limitations of the model in this context.
Impact:
- Highlights significant indoor environmental quality issues in schools.
- Questions the applicability of standard thermal comfort indices (Fanger's) in diverse real-world settings.
- Underscores the need for improved classroom environmental conditions to enhance student well-being and learning.

01:16What is Climate?
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:22Microenvironments
Microorganisms inhabit highly localized spaces known as microenvironments, which are defined by distinct physical and chemical characteristics. These include oxygen concentration, pH, temperature, light availability, and nutrient levels. The conditions within a microenvironment can differ markedly from those in the surrounding area and significantly influence microbial growth, metabolism, and community structure.Microenvironments often display sharp physicochemical gradients over small spatial...
