Bridging the Gap: Empirical vs. Simulation in Green Facade Modeling

Abstract

This paper examines the transformative role of digital simulation tools in architectural design, focusing on the implementation and performance evaluation of green facades in the Global South, particularly Chile. In alignment with the theme The Digital and the South: Questionings, the study highlights how digital simulations enable a critical re-evaluation of sustainable technologies within the unique climatic, social, and urban challenges of southern regions. By addressing the performance gap – the discrepancy between theoretical design and empirical building performance – this research explores how digital tools can bridge this divide, providing essential insights that are otherwise challenging to achieve in unique climatic and urban contexts. This study examines how digital modeling can bridge this gap by providing a deeper understanding of green facades' environmental and energy impacts in different urban microclimates. Using a mixed methodology that combines case studies, empirical measurements, and advanced digital simulations, the research evaluates the potential of green facades to enhance urban climate resilience and energy efficiency. Results indicate that the effectiveness of these facades varies significantly based on local climatic conditions and site-specific characteristics, underscoring the need for tailored architectural solutions to optimize performance. By refining simulation models to capture complex environmental interactions, this paper contributes to more accurate and effective sustainable design strategies, positioning digital simulation as a critical tool for adapting architectural practices to the distinct realities of the Global South.
