Energy implications of control strategies in ventilated facades

Thermal building simulations (TRNSYS) werelinked to nodal airflow network simulations(COMIS) for a detailed ventilated double-skinfacade calculation of performance. Thevalidated simulation model can be used tooptimize the ventilated facade design in respectto reducing the solar heat gains during thesummer period by controlling the exhaustairflow. This may result in significant energysavings and a reduction in systems cooling size.This work evaluates two different controlstrategies of ventilated faqade designs in respectto cooling load reductions. Different controlstrategies can help to reduce cooling load of anoffice up to almost 40%.
