An office air handling unit includes an intake, return and output system. The intake system transfers air from an external environment and through a preheating and cooling unit that regulates the temperature of the air entering the interior zone. The return system re-circulates air from the interior zone to the exterior zone through the use of a fan. The return system also regulates the temperature of the air entering the exterior zone by using a preheat unit and cooling unit. The output system allows for the transfer of air from the exterior zone to the external environment, re circulates the air back into the return system or re-circulates the air back into the intake system. The intake system allows for the transfer of air from the external environment to the return system to bypass the interior zone and provide fresh air to the exterior zone.
