Abstract

Bali is one of the tropical locations where urban heat islands are felt. An alternative that may be discussed in an effort to lessen solar heat radiation in buildings in order to improve thermal comfort without having a detrimental effect on the environment is solar reflecting paint. This study uses the Autodesk Ecotect Analysis 2011 software simulation method to demonstrate the impact of applying a layer of solar reflecting paint coating (Solar Reflectance Index = 106) on the roof of a contemporary Balinese structure. The thermal comfort of the original model and the model covered in reflective paint were compared using simulation data in the form of Mean Radiant Temperature (MRT), Predicted Mean Vote (PMV), and Predicted Percentage of Dissatisfied (PPD). A decline in the MRT, PMV, and PPD values is indicative of a change in the average thermal conditions of buildings, according to the research findings

Abstract

Thermal comfort is an important aspect to achieve in residential buildings. Therefore, this research aims to optimize thermal comfort in residential buildings with Contemporary Balinese Architecture in one of the high-density areas in Bali, namely Gianyar Regency. This study aims to provide design strategy solutions through a descriptive quantitative method in the form of building model simulations using Autodesk Ecotect Analysis software. The optimization focuses on openings and the use of solar reflective paint on the building's exterior to achieve an optimal level of thermal comfort. The results of the case study show that the addition of openings and the use of solar reflective paint can help improve thermal comfort by reducing the MRT (Mean Radiant Temperature) in the building by 0.96°C. The PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) indices were also successfully improved compared to the existing conditions.
