Abstract

Affordable housing subsidised by the government in Indonesia often poses many problems, including an uncomfortable internal environment that leads to the massive use of mechanical ventilation. Designing an affordable house undoubtedly faces challenges due to the very small building lots, while it should provide many spatial needs and functions for the occupants’ daily activities. Because of limited funding provided by the government, affordable house design is often based only on basic needs, thus scarcely considering thermal comfort for the occupants. This study evaluates the thermal performance of affordable houses built for the 2018 great earthquake, tsunami, and liquefaction victims in Palu’s coastal area. Field measurements were conducted in an affordable housing complex, and a sample house was selected, representing a raised floor house design prototype. External and internal climate conditions were recorded for nine days to establish the hourly thermal trend. Hobo Onset H21 microclimate stations were used to record external climate conditions, whereas Onset Hobo U12-012 T-RH-Light was employed to record internal thermal conditions. The result showed that the thermal condition in the sample house was intolerably hot. The main cause of these conditions is the design of the roof and building envelope. The selected materials with a high U-value also worsen the thermal conditions in the sample house

Abstract

The stilt house is one of vernacular architecture features in Indonesia. Several stilt vernacular houses persist until 70 to 100 years old in Palu City. Stilt house forms were proved to be adaptive to tropical climates. This research provides evidence of a thermally comfortable interior created by the vernacular stilt house of Palu City. The research was carried out in two stages: field measurement and thermal comfort value analysis, based on SNI 03-6572-2001 standards. Purposive sampling was used to determine the research sample for vernacular stilt houses. The selected stilt house is located on Anoa street No 57, North Tatura Ward, Palu City. Field measurement was performed to record the indoor and outdoor thermal condition of the sample house employing Hobo Onset U12-012 RH-Light data logger and Hobo H-22 microclimate station. The results show that the outdoor air temperature peak is 36.8°C with 45% humidity. Meanwhile, the indoor peak temperature on the 1st floor reached 32°C with 51% humidity. On the 2nd floor, there are five rooms with peak temperatures ranging from 29.5°C to 34.6°C with 53% to 64% humidity, indicating that each room has a different temperature performance. This condition is due to several parameters, such as ceiling height, roof shape, opening size, room layout, and room orientation. The result also showed that the indoor air temperature tends to be lower than the outdoor air temperature. Hence, it is indicated that the design strategies of the sample building are adaptive to the tropical warm and humid conditions of Palu.
