Summary

The authors investigated a hybrid cooling system, utilizing wind-induced cross ventilation and a radiation cooling panel in an office setting, in order to reduce the energy use for HVAC system in buildings. The utilization of wind-induced cross ventilation seems promising. However, in hot and humid regions such as in Japan, the utilization of natural ventilation only is not sufficient for exhausting the heat generated in offices. An additional auxiliary cooling system is required. A radiation cooling system and an underfloor air-conditioning system were compared. The radiation panel cooling system was found to be more energy efficient and to provide more thermal comfort than an underfloor air cooling system in the case of introducing natural ventilation in a mild climate.
