Ornament and function

Examination of the aerodynamic behaviour of certain decorative building features which when studied demonstrate a useful function in microclimatic wind regulation. The architects and builders in the past lacked our knowledge concerning fluid dynamics, but they exhibited a deep rooted ability to observe and reflect - thus, different cultures have developed by trial and error. The authors have produced a stimulating analysis which couples the science of fluid dynamics and a sensitive understanding of past cultures. The paper is recommended reading.
