Abstract

This study seeks to analyse the thermal comfort level in the University Technical Malaysia Melaka library and compare it with the ASHRAE Standard 55 (2004) and Malaysia Standard MS 1525:2014. Thermal comfort is very crucial for human health as well as productivity especially when people working in big building. Thermal comfort is not only depends on the air temperature but it can be obtained only when there have the proper balance between air temperature, humidity and the movement of the air. The physical measurements were carried out without occupant and with occupant condition. The Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD) for physical measurements and Thermal Sensation Vote (TSV) through subjective assessment were involved in this study’s analysis. Most of the PMV value were between -0 and -2, so the environment temperature in library mostly slightly cool and cool. The Indoor Air Quality measurements for air temperature, relative humidity and air velocity, most of this IAQ were not comply with Malaysia Standard range in both zone for both day and session. The operative temperature for thermal comfort cooling in University Technical Malaysia Melaka library was in the range 19oC to 25oC. The Building Energy Index (BEI) for University Technical Malaysia Melaka library was in range of energy efficient performance and had achieved the best Building Energy Index practice that recommended by Malaysia Standard. The Building Energy Index of University Technical Malaysia Melaka library in year 2015, 2016 and 2017 were 169.27 kWh/m2/year, 141.92 kWh/m2/year and 148.74 kWh/m2/year respectively.
