The potential of hybrid cooling strategies in office buildings to enhance energy efficiency
A hybrid cooling system combines both passive and active cooling systems provides energy savings and improves thermal comfort in hot climates. Natural ventilation is combined with mechanical ventilation by switching to mechanical ventilation when natural ventilation is insufficient to maintain indoor thermal comfort. As air conditioning requires a significant amount of energy, this system is limited in hot climates. This paper examines the application of hybrid ventilation modes in office buildings in Saudi Arabia, with the aim of reducing energy consumption without compromising thermal comfort. A dynamic simulation tool, IES-VE, was used to examine the potential energy savings of the hybrid system through a case study approach. The results of this study indicate that hybrid ventilation mode can save up to 13.7% on an annual basis. The hybrid mode achieved higher savings during the underheating period than during the overheating period at 30.4% and 4.4%, respectively.

Abstract
A hybrid cooling system combines both passive and active cooling systems provides energy savings and improves thermal comfort in hot climates. Natural ventilation is combined with mechanical ventilation by switching to mechanical ventilation when natural ventilation is insufficient to maintain indoor thermal comfort. As air conditioning requires a significant amount of energy, this system is limited in hot climates. This paper examines the application of hybrid ventilation modes in office buildings in Saudi Arabia, with the aim of reducing energy consumption without compromising thermal comfort. A dynamic simulation tool, IES-VE, was used to examine the potential energy savings of the hybrid system through a case study approach. The results of this study indicate that hybrid ventilation mode can save up to 13.7% on an annual basis. The hybrid mode achieved higher savings during the underheating period than during the overheating period at 30.4% and 4.4%, respectively.
