**Dedicated Outdoor Air System (DOAS) Market Segment Insights**

**Global Dedicated Outdoor Air System (DOAS) By Technology Insights**

The Dedicated outdoor air system (DOAS) market has been segmented based on Technology into DX (Direct Expansion) Systems, Energy Recovery Ventilation (ERV) Systems, Enthalpy Wheels and Heat Recovery Ventilation (HRV) Systems. The Energy Recovery Ventilation (ERV) Systems segment accounted for the largest market share in 2024 and Whereas the Enthalpy Wheels segment will likely register the highest CAGR during the projected period.

Energy Recovery Ventilator (ERV) has high efficiency with an alternative ventilation system design that can significantly reduce a building's heating and cooling loads. Pairing DOAS and ERV with a ductless heating and cooling system, such as Variable Refrigerant Flow or Mini-Split heat pumps, can further reduce heating and cooling loads while enhancing comfort. Conventional Heating, Ventilation and Air Conditioning (HVAC) systems must fully temper fresh air before distributing it throughout the building.

This contributes to high heating and cooling loads and means that fresh air is only provided simultaneously with heating or cooling.  DOAS and ERV system combined with a properly downsized heating and cooling system and programmed HVAC controls will generate significant energy savings. Installation of an ERV at the highest efficiency available.

A commercial building's existing ventilation system may either be centralized, providing ventilation to the entire building, or decentralized, providing ventilation to individual floors or spaces. Tech primer outlines a high-performance ventilation upgrade option for commercial buildings using a DOAS with ERV and recommends the installation of an efficient, ductless heating and cooling system (VRF or Mini-Split) to fully realize savings.
