This energy plant’s chillers and cooling towers were reaching an age that replacement was neccesary. Newer technologies were also available that offered significant energy savings. The existing constant speed screw compressor chillers and cooling tower fans have now been upgraded to all variable speed. In addition the hot water system was converted to a primary secondary system with a variable speed, Sensorless Intelligent system pump.
The old, low efficiency boiler was replaced with (3) high efficiency, fully modulating condensing boilers with thermal efficiencies up to 96%. The controls were updated to the latest Tridium N4 System for increased functionality and graphics capability.
They now have a first class mechanical room, topped off with a fresh epoxy coated floor to really showcase the space.
