Abstract

The paper presents the experimental analysis of a small scale building model (1:30), tested into a wind tunnel with atmospheric boundary layer. The objective of the study is to determine the wind influence on the ventilation of a double skin faпїЅade channel (DSF). It was achieved by conceiving and implementation of an experimental program using a wind tunnel. During the experimental work the wind effect over the ventilation of the vertical channels of double skin faпїЅades is evaluated for multiple velocities. For obtaining general results, the average steady state values for velocities are analyzed. The experimental results put in evidence the correlation between the reference wind velocity and the dynamics of the air movement inside the double skin faпїЅade. Thus, the air circulates vertically inside the double skin faпїЅade channel and its velocity is proportional with the reference value and of the same order of magnitude. The experimental results may be used to determine the cooling effect of the ascendant air streams inside the channel upon the external glazing or integrated photovoltaic panels.
