Abstract

Nowadays, g)obaJ wawiog hav~ ~n an jnt~mational jssu~s and world problem. Global warming happens due to the continuing rise in the average temperature of Earth~s atmosphere and oceans. It is because of increased concentrations of greenhouse gases in the atmosphere, resulting from human activities such as deforestation and burning of fossil fuels. These activities contribute to the C02 gasses emissions. Finding has made by IPCC SRES in year 1990 to 2010, the caroon emission increased by year from 21 to 31 (billion tons per year). In order to reduce the heat, a few campaign was conduct and rehabilitation work been done. Every sector in industries especially in building construction they also contribute to the gasses emission by energy consumed by human for living and working. Based on case study, buildings consume one-third of the world energy and worldwide building energy consumption is expected to grow by 45% from year 2002 to year 2025. As in tropical countries experience high levels of heat radiation from the sun and leads to discomfort to humans and surroundings. Air conditioning is widely used to encounter this problem, which consumes high levels of energy. Therefore, this research aims to quantity the reduction in indoor temperature and to verity the positive effect of installing reflective insulation in roofs on indoor parameters. The research methodology consist of I) construction of 2 down -scale model of experimental house (600 x 600 x 500mm) to study the effect of reflective insulation of indoor temperature and 2) insulation material 3) Roof color and 4 ) the house allocated. Data collection is conducted every hour from Sam to 5pm for seven days. The result shows that the insulated houses quantify the most reduction with 37.69"/o and the reduction of temperature difference is at 10.27%. From the result, the behavior of parameters measured show that insulated house has a better thermal performance compared to the coritrol house. ln future it is important to implement a cool roof to preserve our nature and sustainability development.
