Analysis of air temperatures in the cavity of double-skin facades

Non-optimal position of the blinds in double-skin facades can lead to overheating or heat loss. Spring temperature fluctuations and varying solar radiation provide ideal conditions for analysis, highlighting the impact of cavity geometry on thermal performance. This study examines the impact of blind positioning on the cavity air temperature in a double-skin facade during spring. Experimental measurements under different airflow modes showed that a smaller airflow circuit (mode A) produced greater temperature variations (0-7 K), whereas a larger circuit (mode D) resulted in smaller fluctuations (0-2 K).
