The Stability Performance of Indoor Environmental Quality (IEQ) Parameters: Emphasize the Strategies of Sustainable Comforts in the Learning Environment in a Tropical Climate

Abstract

Implementing sustainable construction practices in higher educational facilities in Malaysia would enhance the quality of learning activities. Students in higher education predominantly utilize learning areas. The objective of this study is to evaluate indices of indoor environmental quality (IEQ) that prioritise sustainability in educational environments. The major indicators comprised four significant key terms: Indoor Air Quality (IAQ), Thermal Comfort (TC), Visual Comfort (VC), and Acoustic Comfort (AC). The study utilized data from previous studies published between 2021 and 2023 to determine the present issue that emerged inside Malaysian higher educational facilities. This was achieved by a critical assessment of the parameters' findings via fieldwork measurement. This leads to a spectrum that falls within a satisfactory threshold to attain the desired degree of user comfort. The findings demonstrate that students' comfort level is enhanced by their preference for a stable level of IEQ parameters. According to this study, on average standards of IEQ parameters for a sustainable learning environment; temperature (27°C), humidity (40%), air flow (0.30 m/s), illuminate (400lux) and acoustic (40dB). The strategic framework has been recommended to enhance learning environments and act as a reference guideline for future evaluations of indoor environmental quality.
