Simulation of Thermal Comfort of Heritage Residential House in Bandung using Computational Fluid Dynamic

Abstract

Global Warming is a worldwide issue because it occurs in almost all countries including Indonesia. To anticipate this issue, since the last few years the Green Architecture concept has been established in Indonesia. One of the impacts of implementing this concept is caring for the health of occupants by maintaining air quality and thermal comfort indoors adhering to sustainable principles. Buildings built during the Dutch Colonial period were considered to have paid attention to thermal comfort for their occupants, this is because Indonesia's tropical climate is too hot for those who come from a country with 4 seasons. This paper aims to study the potential of ex-Colonial residential buildings in terms of thermal comfort by studying or analyzing indoor airflow patterns in order to obtain building designs that meet the Thermal Comfort requirements that can be applied to present-day building designs. Quantitative analysis methods are used based on weather measurement data and existing comfort conditions in the field, calculations, and simulations using Computational Fluid Dynamic (CFD) models. The research problem is how the architectural design of colonial buildings adapted to tropical climates? How is the thermal comfort produced in ex-colonial buildings? Analysis of flow patterns in the room will be carried out using the Computational Fluid Dynamic (CFD) method using the Flovent program. In this study, data collection in the field included room conditions (room geometry, materials and equipment specifications used), air conditions (air flow velocity, temperature, humidity) and solar radiation on the research object. In terms of typology and design, ex-colonial buildings for Dutch, Indo-Dutch and indigenous peoples have the potential to fulfill these requirements so that they can be used as a reference and applied to present-day building designs, both those that have been built or those that will be built.
