A system includes an air pressurization system (APS) and an environmental control system (ECS). The APS is configured to supply pressurized supply air to the ECS. The ECS includes a primary heat exchanger (PHX), an air-driven turbine downstream of the PHX, and a vapor cycle refrigeration system (VCRS) 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. The VCRS is configured to cool the supply air to generate cabin air.
