Experimental study of a mechanically ventilated double-skin facade with venetian sun-shading device: A full-scale investigation in controlled environment
The aim of this article is to present results of an experimental campaign performed on a full-scale facility provided with a double-skin facade. The behaviour of this architectural concept is tested under controlled climatic conditions. A summer case is scrutinised under different configurations: variation of the airflow through the double-skin facade and different angle of the solar shading device. This paper describes the experimental conditions, as well the test facility and the tested facade element. The results show the temperatures of the test cell and the facade and how they depend on the climatic conditions and the sun-shading device blade angles. One objective of this research was to measure and provide extensive data set detailing air and surface temperatures on the double-skin facade, together with airflow rates and air velocities. The experiments are fully described so that the results can be used for the validation of numerical models dealing with ventilated double-skin facades with venetian sun-shading device.
