         4 . The AHU of  claim 1 , wherein the cooling coil is in fluidic communication with the energy recovery coil. 
     
     
         5 . The AHU of  claim 1 , further comprising:
 a coolant return basin in fluidic communication with the condenser coil and the energy recovery coil, wherein the coolant return basin is configured to receive fluid flow from the energy recovery coil and excess fluid flow from the condenser coil.   
     
     
         6 . The AHU of  claim 1 , further comprising a fluid pump configured to flow fluid, in order, through the condenser coil, to and through the cooling coil, and to and through the energy recovery coil. 
     
     
         7 . The AHU of  claim 1 , further comprising a motorized fan disposed within the cavity, the motorized fan configured to flow air, in order, through the air ingress, across the cooling coil, across the condensing coil, across the energy recovery coil, and through the air egress. 
     
     
         8 . The AHU of  claim 1 , wherein the cooling coil, the energy recovery coil, or both, comprise a set of fluidic microchannels. 
     
     
         9 . The AHU of  claim 1 , wherein the condensing coil comprises copper tubing with aluminum fins. 
     
     
         10 . The AHU of  claim 1 , further comprising a fluid reheating coil disposed between the energy recovery coil and the air egress. 
     
     
         11 . A method for regulating temperature, comprising:
 flowing a volume of air across a cooling coil of an air handling unit (AHU);   flowing the volume of air across a condensing coil of the AHU;   flowing the volume of air across an energy recovery coil of the AHU; and   exiting the volume of air from the AHU.   
     
     
         12 . The method of  claim 11 , further comprising:
 flowing the volume of air across a fluid reheat coil subsequent to flowing the volume of air across the energy recovery coil.   
     
     
         13 . The method of  claim 11 , wherein flowing the volume of air across the cooling coil decreases a temperature of the volume of air. 
     
     
         14 . The method of  claim 13 , wherein the temperature of the volume of air subsequent to the flowing across the cooling coil is at a dew point relative to the temperature of the volume of air prior to flowing across the cooling coil. 
     
     
         15 . The method of  claim 11 , wherein flowing the volume of air across the condensing coil decreases the temperature of the volume of air. 
     
     
         16 . The method of  claim 11 , wherein flowing the volume of air across the condensing coil decreases a volume of water vapor contained in the volume of air. 
     
     
         17 . The method of  claim 11 , wherein flowing the volume of air across the energy recovery coil increases the temperature of the volume of air.
