A system (100) includes an air pressurization system (APS) (102) and an environmental control system (ECS) (104). The APS is configured to supply pressurized supply air (120) to the ECS. The ECS includes a primary heat exchanger (PHX) (106), an air-driven turbine (108) downstream of the PHX, and a vapor cycle refrigeration system (VCRS) (110) downstream of the PHX. The PHX is configured to cool the supply air using environmental air. The turbine is configured to power a vapor cycle refrigeration system (VCRS) using the supply air (122). The VCRS is configured to cool the supply air to generate cabin air (126).
