DOAS Global Market Report 2026

A Dedicated Outdoor Air System (DOAS) is an HVAC system consisting of two parallel systems. One system is specifically designed for delivering outdoor air ventilation, managing both the latent and sensible loads associated with conditioning the ventilation air. The other system is tailored to handle loads generated by indoor or process sources, as well as those that pass through the building enclosure. DOAS units are typically installed outdoors and are often used in conjunction with other HVAC equipment.

DOAS units are available in different capacities, categorized as less than 20 tons, 20-40 tons, 40-60 tons, and greater than 60 tons. A 20-ton DOAS, for example, has the capacity to remove less than 240,000 BTU (British Thermal Units) per hour. These systems are implemented in various settings, including new construction and retrofit projects, to address heating, cooling, ventilation, and dehumidification needs for commercial, residential, and industrial applications.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are impacting the DOAS market by increasing costs of imported compressors, heat exchangers, control electronics, sensors, and high-efficiency fans used in advanced systems. Commercial and institutional projects in North America and Europe are most affected due to dependence on imported HVAC components, leading to higher system prices and extended procurement cycles. Retrofit projects are particularly sensitive to these cost increases. However, tariffs are also encouraging domestic HVAC manufacturing, regional sourcing of components, and development of standardized DOAS platforms to improve cost competitiveness.

The doas market size has grown strongly in recent years. It will grow from $4.74 billion in 2025 to $5.19 billion in 2026 at a compound annual growth rate (CAGR) of 9.6%. The growth in the historic period can be attributed to expansion of commercial building construction, rising awareness of indoor air quality, increasing adoption of advanced hvac systems, availability of dedicated ventilation solutions, growth in healthcare and institutional facilities.

The doas market size is expected to see strong growth in the next few years. It will grow to $7.58 billion in 2030 at a compound annual growth rate (CAGR) of 9.9%. The growth in the forecast period can be attributed to increasing adoption of net-zero energy buildings, rising investments in smart hvac technologies, expansion of green building certifications, growing retrofit demand in existing buildings, increasing focus on occupant health and comfort. Major trends in the forecast period include increasing adoption of energy-efficient doas units, rising demand for indoor air quality control, growing integration with smart building systems, expansion of retrofit installations, enhanced focus on humidity and ventilation management.

A global shift towards sustainable and environmentally conscious building practices is anticipated to propel the growth trajectory of the DOAS market. Sustainable and green building practices revolve around eco-friendly, resource-efficient design, construction, operation, and maintenance approaches aimed at minimizing environmental impact while enhancing occupant health and well-being. Within this context, DOAS emerges as a crucial component in sustainable building methodologies, offering solutions for improved indoor air quality, energy efficiency, and occupant comfort. For instance, according to the Building and Construction Authority (BCA), Singapore aimed to have approximately 55% of its buildings eco-friendly by the end of 2022. Furthermore, Singapore's Green Building Masterplan targets greening 80% of the country's buildings by gross floor area (GFA) by 2030. This concerted global emphasis on sustainability and green practices serves as a driving force propelling the growth trajectory of the DOAS market.
