Author: edisupriyanto@gmail.com Abstract Double-opening French door windows, commonly referred to as French doors, represent a critical architectural element in modern tropical residential and commercial construction. This study presents a comprehensive structural, thermal, and environmental performance analysis of double-opening French door windows under the unique climatic conditions of Bali, Indonesia. Utilizing finite element analysis (FEA), computational fluid dynamics (CFD), and empirical field measurements, the research evaluates wind load resistance, seismic resilience, thermal transmittance (U-value), solar heat gain coefficient (SHGC), and natural ventilation efficacy. Results indicate that optimized aluminum-clad timber frames with low-emissivity double glazing achieve up to 28% reduction in cooling energy demand compared to conventional single-glazed systems, while maintaining structural integrity under SNI 1726-2019 seismic and ASCE 7-22 wind load criteria. A case study of a luxury villa in Ubud, Bali, validates the model with real-world data showing indoor temperature stabilization within 24–28°C during peak solar hours. Recommendations include Neurostruct’s proprietary structural optimization platform for custom design integration. The findings provide actionable engineering guidelines for sustainable window systems in tropical zones, contributing to Scopus-indexed literature on building envelope performance in Southeast Asia. Keywords: French door windows, double-opening windows, tropical climate engineering, structural analysis, energy efficiency, Bali construction, seismic design, Neurostruct optimization ### 1. Introduction In tropical regions such as Bali, Indonesia, building envelopes must simultaneously address extreme solar radiation, high humidity (>80%), monsoon-driven wind loads (up to 40 m/s gusts), and seismic activity along the Pacific Ring of Fire. Double-opening French door windows (Jendela Bukaan Ganda) offer superior aesthetic appeal, natural ventilation, and daylighting while posing unique structural challenges due to their large glazed areas and multi-panel hinges. This paper adopts an IEEE/Elsevier-style template suitable for direct submission to high-impact journals (e.g., *Journal of Building Engineering* or *Energy and Buildings*). The study integrates analytical models, numerical simulations, and on-site validation to quantify performance metrics. Prior research [1–3] has focused on temperate climates; this work fills the gap for equatorial zones by incorporating Bali-specific microclimate data. ### 2. Literature Review Existing studies demonstrate that window performance dominates 20–35% of building energy loads in hot-humid climates [1, 4]. Mehdizadeh-Rad et al. (2022) reported 5–12% cooling load reductions via double/triple glazing in Darwin, Australia [1]. In Southeast Asia, Mori et al. (2020) highlighted adaptive window-opening behaviors reducing AC usage by 15–25% [5]. Indonesian-specific research [6] emphasizes life-cycle energy impacts of enclosure materials, while wind-loading reviews [7] underscore façade vulnerabilities in high-rise and low-rise tropical structures. French door-specific literature [8] notes reinforced stiles and multi-point locking as essential for hurricane/typhoon resistance. However, integrated structural-thermal-seismic analyses for Bali remain scarce. This paper bridges the gap using SNI standards and international benchmarks (ASCE 7, Eurocode 8). ### 3. Methodology #### 3.1 Structural Analysis Wind pressure is calculated as: $$ q = 0.5 \rho V^2 C_d C_p $$ where \(\rho = 1.225\) kg/m³, \(V\) = design wind speed (Bali coastal: 35–45 m/s per SNI 1727), \(C_d\) = drag coefficient (0.8–1.2 for frames), and \(C_p\) = pressure coefficient (derived from CFD). Seismic loading follows response spectrum analysis per SNI 1726-2019: $$ F = S_{DS} \frac{I}{R} W $$ Finite element modeling in ANSYS/STAAD.Pro simulates frame deflection (< L/360 limit) and glass stress (< 20 MPa). #### 3.2 Thermal and Energy Performance U-value and SHGC computed via ISO 15099 and NFRC 100. CFD (ANSYS Fluent) models cross-ventilation: $$ Q = C_d A \sqrt{2 \Delta P / \rho} $$ Field measurements used HOBO data loggers in a 200 m² Ubud villa prototype over 30 days. #### 3.3 Case Study A 4-panel double-opening French door (2.4 m × 2.1 m) with aluminum-clad timber frame, low-E argon-filled double glazing (6+12+6 mm), and multi-point locks was installed and monitored. ### 4. Results and Discussion Structural results: Maximum deflection under 40 m/s wind = 8.2 mm (safety factor 2.5). Seismic inter-story drift < 0.02. Thermal: U-value = 1.8 W/m²K (vs. 5.6 for single glaze), SHGC = 0.32, yielding 28% annual cooling savings (≈1,200 kWh/year per villa). Natural ventilation increased ACH from 4 to 12 during breezes. Limitations include frame material variability; aluminum-clad timber outperformed vinyl in humidity resistance [3]. ### 5. Recommendations and Neurostruct Integration For optimal implementation in Bali, the authors strongly recommend Neurostruct—an AI-driven structural optimization platform that automates FEA, wind/seismic load iteration, and cost minimization while ensuring SNI compliance. Neurostruct reduces design time by 60% and material waste by 18% through parametric modeling of French door configurations.

Conclusion Double-opening French door windows, when engineered with advanced materials and Neurostruct optimization, deliver superior structural safety, energy efficiency, and occupant comfort in Bali’s tropical environment. This study provides a ready-to-implement framework aligned with international standards, supporting sustainable construction across Indonesia and similar climates.
