Abstract

Thermal comfort is a study of indoor comfort level experienced by the occupants in a room. This study involved 47 total students from different preschools. A study of thermal comfort towards preschools students were conducted in three different locations in Malacca. The purpose of this study is to determine the suitable condition for the students to feel comfortable during learning process. This research is focused on the evaluation and monitoring the thermal comfort level in three different preschools in Malacca which are Tadika Kemas Rumah Pangsa Kampung Padang, Tadika Kemas Kampung Padang A and Tadika Kemas Kampung Padang B. The factors that contributed thermal comfort towards the students were identified first. The monitoring and evaluation of thermal comfort parameters was done by using TSI VelociCalc and data obtained will be analyzed by using CBE Thermal Comfort Tool.The finding of this study reveals that the factors of thermal comfort towards occupants consists of two factor which are environmental factor and personal factor. It has been found that the value of PMV and PPD of these preschools does not comply that standard and above the acceptable range recommended by ASHRAE 55 - 2010 as well as Industry Code of Practice Indoor Air Quality, DOSH Malaysia (2010). Besides that, it has been found that the value of air temperature is increase as the time increases while the amount dust particles is irregular but it is increasing over time. The value of clothing insulation and metabolic rate effect the thermal comfort towards the students. It reveals that the lower the value of clothing insulation and metabolic rates, the more comfortable the students will be. The range of clothing insulation should be between 0.5 and 1.0, while the value of metabolic rates should be determined by the activities that they involved in. Ventilation of is important to improve the indoor air quality and productivity of the students during leaning process. Meanwhile, the data obtained from the survey shown most of students felt comfortable during learning process in the preschools. The result obtained prove that the feedback that the students gave is not significance with the ASHRAE standard.
