The thermal performance of ventilated double skin facade had been investigated by experimental studies and numerical modeling simulations in recent years.
The models that have been used to predict the performance of DSF reviewed by Gracia et al.[4] included: a) Lumped model for naturally ventilated DSF[11-13]; b) Non-dimensional analysis for describing the energy performance of DSF [14, 15]; c) The airflow network model for naturally ventilate DSF in commercial building; d) Control-volume approach using one dimensional vertical air flow[16]; e) CFD approach for air channel velocity and temperature distribution simulation [14, 17]; f) Zonal approach, using larger control volume to calculate, the algebra equation is simpler than CFD approach [18].
