| summary |
A screen wall composed of breeze blocks is a simple and aesthetic means of improving the sun shading performance and ventilation of buildings. However, they are gradually being replaced by mechanical systems and sealed curtain wall envelopes in contemporary constructions. This article presents a digital method to analyse breeze blocks that elucidates their complex form–performance relationship, which is a timely response to the recent revival of breeze block applications in architectural design. Through the study of architectural cases in Hong Kong built in the 1950s and 1960s, the environmental performance of breeze blocks was quantified and represented digitally, which enabled the comparison of different breeze block types. Rhinoceros 3D and Grasshopper were used as the modelling and visualisation platforms, with Radiance and BlueCFD-Core as the simulation engines. The findings revealed that breeze blocks have a three-dimensional quality based on typological variations in terms of geometry, proportion, dimensions, and perforation. The results of this article present a method that contributes to the study of the environmental performance of breeze blocks to optimise and inform new architectural applications. |
