The document discusses sustainable air conditioning solutions that use less energy and water. It introduces the Ambiator, a two-stage air conditioning system that uses 100% fresh air and has an efficiency of 55-60%. It also uses evaporative cooling and has lower power and water consumption than traditional AC. The document also describes the Toro Hybrid air handling unit, which uses a combination of free cooling and chilled water to provide comfort cooling with 30% less energy use compared to refrigerative cooling alone. Both solutions provide more sustainable alternatives to traditional AC.
