Dedicated Outdoor Air System (DOAS) - Worldwide

The global dedicated outdoor air system (DOAS) market size was exhibited at USD 4,119 million in 2024 and is projected to hit around USD 9,841 million by 2034, growing at a CAGR of 9.1% during the forecast period 2024 to 2034.

The dedicated outdoor air system market delivers fresh, dehumidified air separately from traditional heating and cooling, ensuring proper ventilation in environments such as hospitals and schools. The growing focus on indoor air quality and energy efficiency is driving demand for these systems. Demand in the dedicated outdoor air systems market is growing, especially in healthcare, commercial, and educational settings. Increased awareness of the health benefits of fresh air, linked to fewer respiratory issues and better cognitive performance, is driving this trend. Federal governments across the world are undertaking projects in collaboration with private decarbonization retrofit projects for private sector buildings across Canada, targeting commercial, manufacturing, and multi-residential sectors. 

Despite this, the dedicated outdoor air system market faces certain obstacles to growth, including a lack of consumer awareness about the benefits and complexities of DOAS, which leads to the high cost of installation and maintenance, which becomes prohibitive, especially in emerging economies despite their potential for significant energy savings. However, the booming construction industry, especially in the Asia Pacific region, is increasing the demand for HVAC systems, particularly dedicated outside air systems, due to new builds and upgrades to existing structures.
