EFFECT OF DIFFERENT TYPES OF PAINT TO RESIDENTIAL BUILDING

Abstract

In recent years, Malaysia has experienced climate change that leads to the higher consumption of energy dueto the increasing outdoor temperature that affects indoor discomfort conditions. Paints were found to be the insulationmaterial that is increasingly important because of their benefits in terms of thermal comfort and energy savings. Therefore,the aim of this study is to determine the effect of different types of paint to the residential building. Two types of paints wereapplied on indoor walls of identical room and their performance was compared. The equipment used to measure theperformance includes data logger and thermocouple for temperature performance and lux meter for illuminationperformance. The experiments consider the impacts of paints on interior surface temperature, wall orientation, indoor airtemperature and the illuminance level. The result shows that the air temperature of the room was brought down considerablyat about 1.9°C by implementing the reflecting paint on the indoor walls. The most significant effect is on the surfacetemperature with the highest temperature reduction of about 2.8°C which occurs at west wall after the application ofreflective paint that makes it as the best location to use reflective paint. For illumination, the results show that reflective paintgives significant effect compare to energy saving paint with the highest illuminance level of 392 lux. With the application ofreflective paint, the indoor temperature is improved and thus minimized the energy usage. Reflective paint has also presentedthe ability to reduce the indoor temperature, the effective wall orientation when applying it and improves the illuminancelevel of indoor building.
