Title : The Existence and Role of Attic Ventilation in Housing Estates in a Humid Tropical Climate

Abstract :

Traditional Indonesian architecture and Dutch colonial architecture in Indonesia often have an attic as an intermediate space with openings for ventilation and natural lighting. Most of the houses in residential areas in Manado have corrugated zinc roofs and no longer use attic ventilation. This article aims to examine the benefits of attic ventilation in zinc-roofed buildings and to determine the existence of roof ventilation and the thermal comfort conditions of residents in Griya Paniki Indah (GPI) housing, Taman Mapanget Raya (Tamara) housing, and Kharisma Koka (KK) housing. The benefits of roof ventilation were investigated by constructing and comparing two similar test cells in which one cell had roof ventilation and the other did not. The air temperature in the test cell with a ventilated roof is always 1.2 °C lower than the air temperature in the cell without roof ventilation. Almost all houses in the three residential areas have a modern and minimalist architectural style with roofs that do not allow roof ventilation. All respondents stated that they always felt uncomfortable or hot to very hot from daytime to night. As a result of these conditions, the residents' efforts to regulate the climatic conditions of the room by using air conditioning, fans, or opening windows and ventilation throughout the day. There is a need for comprehensive socialization of the benefits of attic ventilation applications to the wider community, which in turn is an effort to achieve thermal comfort and energy savings in the construction and housing sectors.
