Abstract
The article describes the outcomes of the monitoring campaign carried out in an educational building nearby Tirana, capital of Albania. Performed under the bilateral agreement between the National Research Council of Italy and the Ministry of Education and Sport of the Republic of Albania, the study proposes a combined approach for the assessment of the IEQ, not limiting only in the collection of objective data through the environmental monitoring of indoor variables but it also includes the subjective perception of indoor environment by the students through the compilation of a specific questionnaire. The classrooms were also modelled using a parametric model combining the functionalities of Honeybee plugin with OpenStudio and Radiance. The results are illustrated by maps of the indoor microclimate and illuminance with spatial resolution of 0.5 meters and one-hour temporal resolution step. Aggregated index and environmental data derived from models are compared to those monitored with nEMoS. This hybrid method overcomes the drawback caused by a low resolution of the monitoring steps and allows the comparison of the objective and subjective perception of the considered environmental factors, as well as the identification of discrepancies in terms of objective evidence and subjective perception related to the considered environmental factors.
Highlights
The Indoor Environmental Quality (IEQ) is today fundamental to guarantee safety, wellbeing, health of building occupants and their productivity as well
The main goal of the research is the evaluation of the main aspects of IEQ in two classrooms in the “Kolë Jakova” school in Albania using two smart devices developed with the Do It Yourself (DIY) philosophy and a survey to evaluate pupils’ perceptions within the indoor environment
Another important limitation of the study is related to the duration of the monitoring campaign: only three days that are not enough to perform the calibration and validation of the models
Summary
The Indoor Environmental Quality (IEQ) is today fundamental to guarantee safety, wellbeing, health of building occupants and their productivity as well. Children spend about 30% of their daily-time and adequate IEQ levels are mandatory to guarantee their health and performance. In spring 2017, [2] obtained similar results with a survey carried out in 21 Dutch schools, where the major cause of discomfort was again poor air quality. The results of the objective measurements made by [4] revealed low levels of IAQ and light in conventional schools. Low IEQ levels in educational buildings directly affect pupils’ performance in learning. The current research considers the most influential aspects of indoor environmental comfort (thermal, lighting and IAQ) as reported by the above-mentioned literature, carrying out a monitoring campaign and a modelling activity and analysing the perception of pupils during school time, in intermediate season
