Building is considered as the most energy-consuming sector, gaining over 30% shares among the others globally as well as a prominent carbon dioxide (CO2) emitters. With the increasing of urbanization phenomena, it is inevitable that the future trend will lead to denser housing. Consequently, electricity demand raise will follow. Green roof stands as the one of promising solution to suppress this problem. A set of experimental activity was designed to measure thermal performance of a building installed with green roof in Bandung. It represents typical days during dry and rainy season. Moreover, a novel energy building simulation software has been used to model actual green roof parameters. Those will act as a baseline to conduct a real case building simulation during the same period. Experimental data shows that the presence of green roof may increase building temperature stability. It cools building while ambient gets hot and vice versa. The real case building model has also been conducted. Revealing that by using additional green roof construction may reduce facility cooling load by 20.5% in dry season and 12.7% in rainy season.
