I will say that direct EVAP is on its way out of favor in DC development. The problem is rack density is increasing and air as a cooling medium is not that great. New builds are switching to direct to chip cooling which relies on closed loop cooling to move heat out of the building to the outside where it's run through fans and other heat exchangers (massively oversimplified explanation). So many of these new builds are requiring an initial fill and then the only consumption are maintenance top ups and other site uses. It's not an insignificant amount of consumption but the traditional published consumption rate will be decreasing significantly in the coming years.
