ENERPOS
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.
Dedicated outdoor air system
Compared to other sensible cooling systems, radiant ceiling cooling panels are the best parallel system choice for use with the DOAS. Because the DOAS only accommodates the space ventilation and latent loads, it provides an opportunity to reduce the required floor-to-floor height by reducing the size of the duct system and the required fan power. There are numerous advantages of a radiant ceiling cooling system coupled with a DOAS. The general evaluation section in 2008 ASHRAE Handbook gives a brief description as follows:
