Comparison of Static Model, Adaptation Study, and CFD Simulation in Evaluating Thermal Comfort Based on Köppen Climate Classification System in Churches in Indonesia

Abstract

This research examined thermal comfort in church buildings in Indonesia by making a comparison between three different Indonesian climatic regions using three different research models. A static model, an adaptation study model and a CFD simulation were used to find the similarities and differences between the results generated from determining thermal comfort in church buildings in the three regions. The comparison revealed that church buildings had different PMV scores at each measuring point that were inversely proportional to the subjects’ response on thermal comfort inside the buildings, i.e. points adjoining with openings affect a low PMV score and a high perceived thermal sensation, and vice versa. The CFD simulation showed that changing the conditions of the openings affects air velocity and flow into the building, which influences the subjects’ thermal comfort response inside the churches.

Literature review: The effect of environmental arrangement on malaria incidence in dry tropical climate areas in NTT

“…In the Koppen climate classification, the tropical climate in Indonesia is divided into 3 (three) climate types, namely tropical rain forest climate (Af), Monsson (Am) and Tropical Dry/savanna (Aw). Of the three climate types, East Nusa Tenggara, especially Sikka Regency, is an area that falls into the dry tropical climate type and has the highest cases of malaria spread in 2022 [1].…”
