Dedicated Outdoor Air System Market Growth & Trends

The global dedicated outdoor air system market size is anticipated to reach USD 9,298.7 million by 2033 and is projected to grow at a CAGR of 6.4% from 2025 to 2033, according to a new report by Grand View Research, Inc. The dedicated outdoor air system industry is primarily driven by the growing emphasis on energy-efficient HVAC solutions, rising construction of commercial and institutional buildings, and increasing awareness of indoor air quality and occupant health. The growing trend toward green building certifications such as LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment Method) has also reinforced the adoption of DOAS units as they ensure compliance with ventilation and humidity standards while reducing energy consumption.

Market opportunities lie in the integration of smart controls, variable refrigerant flow systems, and advanced heat recovery technologies that improve performance and lower operational costs. Emerging economies in Asia-Pacific and the Middle East are witnessing large-scale investments in commercial infrastructure, offering significant growth potential for manufacturers. In addition, the retrofitting of existing HVAC systems with DOAS to meet modern energy codes presents a major opportunity across developed markets.

The market is shaped by regulations emphasizing sustainable construction and indoor environmental quality, including ASHRAE Standard 62.1, the U.S. Department of Energy’s energy efficiency mandates, and the European Union’s Energy Performance of Buildings Directive (EPBD). These regulations encourage the use of ventilation systems capable of providing precise control of temperature, humidity, and air purity, driving DOAS system implementation in both new and renovated buildings.

Leading players such as Carrier, Daikin Industries, Trane, Johnson Controls, and LG Electronics are focusing on expanding product portfolios through energy-efficient and smart-enabled DOAS solutions. Their strategies include the use of variable speed compressors, intelligent sensors, and modular system designs to improve part-load efficiency. Many are also investing in regional manufacturing facilities and strategic partnerships to strengthen distribution networks and enhance responsiveness to local market demands. For instance, in July 2025, Greenheck Fan Corporation expanded its DOAS product line with the RV-220 model, offering up to 29,200 cfm airflow, 50–100 tons packaged DX cooling, and 2,000 mbh indirect gas heating.

Dedicated Outdoor Air System Market Report Highlights

Based on capacity, the up to 20 tons capacity segment accounted for the largest market revenue share in 2024, as it is widely preferred in small to medium-sized commercial buildings, schools, and healthcare facilities where space constraints and moderate ventilation loads demand compact, energy-efficient DOAS units.
Based on end-use, the commercial segment accounted for the largest market revenue share in 2024, owing to the increasing adoption of DOAS units in offices, retail spaces, educational institutions, and hospitality facilities, where maintaining optimal indoor air quality and occupant comfort is a top priority.
Based on equipment type, the packaged DOAS units segment accounted for the largest market revenue share in 2024, due to their ease of installation, compact design, and lower maintenance requirements compared to split systems.
Asia Pacific led the market with the largest revenue share in 2024, driven by accelerated urban development, growing commercial construction, and a strong focus on energy-efficient HVAC technologies. Supportive government policies promoting green buildings and better indoor air environments are further propelling the adoption of DOAS solutions.
In April 2025, Johnson Controls announced its decision to divest its global HVAC (Heating, Ventilation, and Air Conditioning) solutions business for residential and light commercial buildings, including its stake in the Johnson Controls-Hitachi joint venture, to Bosch for USD 8 billion. This transaction marks a strategic move by Johnson Controls to streamline its business portfolio.
