Finally, large ceiling fans are installed in every room, even those using air conditioning. Ceiling fans ensure that even in the absence of the necessary breezes, the airflow needed to feel comfortable in the room is provided for the users. This solution significantly reduces the amount of energy consumed. The overall consumption of the ceiling fans and the split system (the latter used to cool the technical rooms) is only 3.7kWh/m².yr compared to a classic air conditioning system in a standard building consuming 80kWh/m².yr.

"Fins" along the building's walls are designed to channel the prevailing north-east winds into the building. Wind tunnel tests conducted at the National University of Singapore found that the "fins" would enhance the air flow by 20 to 30%. Sunshades over the windows protect patients from the direct glare of sunlight. The shades also re-direct light towards the ceiling to enhance the brightness of the wards and save on the use of energy. Large fans in public areas are powered by solar panels on the roof. The air-conditioning system draws supply air from its internal courtyards, where the air is cooler, hence reducing the cooling loads.
