The Shaw method or process for air conditioning increases cooling energy efficiency by 
30-50% compared to traditional systems. This is achieved through:

· The ability to prevent ‘over cooling’ in humid climates
· Scheduling of chilled water leaving water temperatures up to 15 degrees 
  (not traditionally available in conventional systems)
· Humidity control enables temperature to be elevated

The twin coil designed system differs from conventional air conditioning principles. 

Outside air is pre-treated through a de-humidification coil and cooled with chilled water before contacting the inside air. The supply air is treated by the second coil which belongs to the original system.
