| Abstract |
This study aims to evaluate the feasibility of a lightweight triple-glazed glass with a 0.5 mm center pane as a high-performance alternative to
conventional glasses, developed in response to South Korea’s expanding Zero Energy Building (ZEB) mandate. The lightweight triple-glazed
glass was assessed for application to multi-family residential buildings through comparative analysis of energy performance, economic, and
constructability against conventional double- and triple-glazed glass. Simulations using Window v7.8 demonstrated that the lightweight
triple-glazed glass achieved the lowest U-value of 0.586 W/m²·K and reduced annual heating and cooling demand by up to 4.7% compared
to double-glazed glass. Although it incurred the highest unit cost (202,893 KRW/m²), it significantly reduced tower crane hoisting time to
8.99 hours, confirming advantages in constructability under repetitive installation conditions. A Technique for Oder of Preference by Similarity
to Ideal Solution (TOPSIS) evaluation ranked the lightweight triple-glazed glass as the best overall option. These results indicate that the
proposed glazing provides both technical efficiency and practical viability, supporting its potential as an effective solution for ZEB realization. |
