- Abstract
The increase in urban temperature because of the urban heat island phenomenon affected energy usage for the building sector. Most of the energy usage in the building is for the air conditioning system to achieve thermal comfort. It is necessary to reduce the cooling load by minimizing heat gain to the building so that the air conditioning system uses less energy consumption. Passive design with a green roof system offers a solution to reduce heat gain from solar radiation through the roof. However, only a few buildings have implemented a green roof system in the tropics, especially in Indonesia, and the literature found on this subject is also inadequate. This research studies the thermal performance of precast lightweight foamed concrete as a roof structure integrated with a green roof system through experimental modeling. We constructed two prototype rooms with the precast foam concrete panel as the roof. One prototype uses a green roof and the other without a green roof. We expose the prototypes to an open environment with direct sunlight for 3 days. The air and surface temperatures inside and outside the models were measured continually at the 10-second intervals. The thermal performance of the green roof is evaluated by comparing the thermal responses of the models during the exposure. The results show that the green roofs significantly reduce the heat load from solar radiation during the day.
