Abstract

Validation model was generated by WINDOW 7.6 software to simulate the temperature changes of laminated glass. This approach is used as a validation model to compare the real time temperature changes observed. The parameter in the test were clear laminated glass and coloured laminated glass with using singleand double-glazed technology to assess the impact of optic glass, including U-Value, SHGC, and additional layer application of laminated Glass (Double Glazing Technology) in building temperature changes for creating thermal comfort. The results showed that single glazed technology application on clear laminated glass adjust the room temperature between 30.2°C to 31.4°C. In comparison, single colour laminated glass technology application set the room temperature 27.7°C to 28.5°C. Interestingly, the double-glazed application reduced the indoor temperature between 27.1°C to 28.5°C. These results showed that buildings’ significant thermal performance could be accomplished by applying doubleglazed technology. Nevertheless, double glazed technology was not suggested to apply in all of the skin of tropical building design due to the high-cost issues.

Highlights

Population growth, the evolution of the construction industry, and increasingly advanced technology have led to an increase in the construction of glass-glazed high-rise buildings [1]
Thermal comfort is defined as a state of mind that expresses satisfaction toward the thermal environment [4]
The U-value measures the transmission of heat circulated through the window, while the Solar Heat Gain Coefficient (SHGC) measures the transmission of solar radiation through the glass

Summary

Introduction

Population growth, the evolution of the construction industry, and increasingly advanced technology have led to an increase in the construction of glass-glazed high-rise buildings [1]. Glass-covered buildings have grown into an icon in various developing countries, such as Indonesia [2]. Laminated glass is one type of glass that is found in Indonesia, especially in Jakarta, this is due to its relatively low price and low property value of laminated glass. Provides visual communication with the outdoor space and enhances the aesthetics of the building [3]. In tropical climates, glass allows solar radiation to enter interior spaces, causing unfavorable thermal comfort for the occupants. Thermal comfort is influenced by two variables, notably personal variables, including metabolic rate and clothing insulation and environmental variables, including air temperature, air velocity, and humidity [5]
