Abstract

Whilst the use of louvres for the control of solar radiation and daylight has been extensively studied, their impact on airflow through window openings seems to be relatively poorly researched. An experimental study has been carried out to investigate the airflow characteristics through a system of modulated louvres. The pressure flow characteristics across a full-scale louvre system were measured. Airflow models were developed for different louvre inclinations using quadratic relationships of the form ΔP = AQ² + BQ and compared to the power law expression of the form ΔP = aQ". The changes to airflow at various angles of louvre inclination for a range of pressure differences were also evaluated.
