  High-rise office buildings frequently experience airflow stagnation zones on windward façades, particularly at mid-height levels where wind streams divide upward and downward. These stagnation effects limit natural ventilation potential and increase reliance on mechanical cooling during warm seasons. This study investigates how parametric façade aperture design can strategically enhance airflow distribution and reduce cooling loads in high-rise office buildings. Focus on Stagnation-Level Floor and Design Hypothesis The research concentrates on the floor intersecting the façade stagnation point, where airflow dynamics are most constrained. It is hypothesized that optimized aperture geometry and spatial distribution can redirect pressure differentials to improve indoor ventilation performance and thermal comfort, thereby reducing cooling energy demand without mechanical intervention. Multi-Stage Methodological Framework A multi-stage methodology was implemented integrating com...

Thermotropic (TT) glazing has demonstrated strong energy-saving potential in air-conditioned office buildings located in hot climates. However, its applicability and performance in mixed-ventilated residential buildings—particularly when assessed using the adaptive thermal comfort model—remain insufficiently explored. This study addresses this gap by evaluating TT glazing performance across multiple building performance indicators in residential contexts. Simulation Model Development and Validation A comprehensive building performance simulation model was developed and validated using experimental data to ensure reliability. The validated model enabled accurate assessment of TT glazing behavior under varying climatic and operational conditions, forming a robust foundation for comparative performance analysis against conventional double-clear glazing. Evaluation Framework for Mixed-Ventilated Buildings The study employed a multi-dimensional evaluation framework incorporating availa...
