Analysis of Indoor Thermal Comfort for Sustainable and Green Building Applications: A Case Study of Lecture Halldy of Lecture Hall

Abstract

Most human activities are spent indoors in this technological age, ranging from work, study, play, rest, or other activities. Moreover, it takes a comfortable room in order to improve performance. Along with constructing a new lecture hall in IPB University, there is a need for research for thermal comfort whether the building has met the standards of thermal comfort. Research data is obtained through direct measurements. Measurements taken are measurements of temperature and relative humidity. Data collection for each parameter was carried out three times and conducted in eleven lecture halls from April to May 2021. Thermal comfort in lecture halls for air temperature meets the quality standard, with the highest value of 25.60 °C while the lowest value is 23 °C. Relative humidity does not meet the quality standard, with the highest value of 79.97%, while the lowest value is 64.80%. The level of indoor comfort obtained in ASHRAE-55 shows that PMV and PPD values in lecture halls mostly qualify for comfortable and relaxed conditions, i.e., with a value of -0.8 ≤ PMV ≤ 0.5 and PPD ≤ 20%. This indicates the physical condition of the air in the lecture hall is quite comfortable to do lecture activities.
