Indoor Environmental Quality Towards Classrooms' Comfort Level: Case Study At Malaysian Secondary School Building

The indoor environmental aspects of classrooms in secondary school buildings need to be determined to ensure that they meet the users’ basic requirements. Students’ efficiency and learning productivity can be affected if the classroom’s indoor environment is of poor quality. The question raised here: how can we ensure that the comfort level provided to building users in terms of indoor aspects is up to their satisfaction? Post Occupancy Evaluation (POE) is an instrument to examine the success of building design and performance after occupancy. It indicates users’ satisfaction and comfort level related with the indoor environment. Considering users as a benchmark, there is a large potential for improvement in buildings’ indoor environmental aspects. As reflected by the title, the study’s main purpose is to evaluate students’ satisfaction and perception of their classrooms’ comfort level along with recommendations to enhance the quality of their indoor environment. The survey method applied in this study is by distributing questionnaires to 382 students in classrooms where physical measurements were taken to determine how environmental aspects affect these students. This is because these students are highly correlated with the level of comfort and productivity in the classroom. To enhance physical satisfaction during the learning process, semi-structured interviews consisting of 35 experts in related fields were selected, of whom 17 experts are those with a technical background while the remaining 18 experts are from non-technical fields. The results of this interview will be integrated in finding the best methods to improve Indoor Environment Quality in the classroom. The paper recommends the adaptation of POE in order to evaluate the indoor environmental aspects of classrooms as significant learning spaces in school buildings that need to be managed and monitored continuously.
