Passive Application through Solar Induce Ventilation on Sustainable Building in Equatorial Hemisphere

In the last couple of years and years to come Indonesia, Singapore, Thailand and Malaysia are having the highest GDP growth in ASEAN (South East Asia Nations) member countries; at present Indonesia has the highest GDP, it was $845 billion in 2011 and is predicted to grow up to $ 2,200 billion in 2030. In line with economic growth the countries energy demand also sharply increases, Indonesia primary energy demand has increased four folds in the past 30 years, while the region increase almost five folds. The main energy consumer in the country mainly coming from transportation sector, followed by industrial and residential sectors, while buildings combined (residential and commercial sector) accounted in more than 30% from the total energy consumption.The study focused on alternatives cooling appliances through passive method, where electricity and other source of energy are very limited to be used. The highest cooling appliances for middle class houses are either standing fan or ceiling fan, an alternatives design is developed and simulated by using CFD modeling tools with a tropical climate in Jakarta as the boundaries. The study shows that the passive method could reduce in more than 1800 kg CO2eq annually.
