DOAS Market Report 2025

The DOAS market size has grown strongly in recent years. It will grow from $4.45 billion in 2024 to $4.83 billion in 2025 at a compound annual growth rate (CAGR) of 8.5%. The growth in the historic period can be attributed to demonstrated benefits in energy savings, commercial and institutional adoption, focus on occupant comfort, renovation and retrofitting projects, demand for improved indoor air quality.

The DOAS market size is expected to see rapid growth in the next few years. It will grow to $7.17 billion in 2029 at a compound annual growth rate (CAGR) of 10.4%. The growth in the forecast period can be attributed to COVID-19 pandemic impact, demand from commercial and institutional sectors, integration with smart building solutions, focus on comfort and control, renovation, and retrofitting activities. Major trends in the forecast period include energy efficiency regulations, focus on indoor air quality (IAQ), green building certifications, HVAC system upgrades and renovations, adoption of variable refrigerant flow (VRF) systems.

The growing number of residential and commercial construction projects is expected to drive the expansion of the DOAS (dedicated outdoor air systems) market. Construction activities encompass building, modifying, repairing, and remodeling infrastructure or facilities. The construction sector includes both residential and non-residential infrastructure, such as commercial, industrial, and institutional buildings. DOAS are widely used across various types of buildings, with their selection influenced by factors like the building’s environment, age, the preferences of the owner and project designer, the project’s budget, and the overall building design. For example, in July 2023, the Australian Bureau of Statistics reported that the number of dwellings under construction in the March quarter of 2023 increased by 1.3%, reaching a total of 240,813 units, surpassing the previous record of 240,065 units in March 2022. Thus, the increase in residential and commercial construction is driving the growth of the DOAS market.

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.

Product innovations are emerging as a key trend in the DOAS (Dedicated Outdoor Air Systems) market. Leading companies in this sector are increasingly focused on developing innovative solutions to solidify their market positions. For instance, in September 2024, AAON, a US-based company specializing in HVAC systems, introduced the Delta Class, a new line of DOAS technology. The Delta Class features variable capacity compressors, modulating reheats, 100% outdoor air dampers, and advanced energy recovery systems. It is designed specifically for high-occupancy spaces like schools and fitness centers, aiming to enhance indoor air quality while minimizing carbon emissions. Thoroughly tested at the Norman Asbjornson Innovation Center, the Delta Class represents AAON's commitment to innovation and sustainability in HVAC solutions, continuing its legacy of providing high-performance equipment since 1988.

Prominent companies within the Dedicated Outdoor Air Systems (DOAS) market are strategically investing in initiatives aimed at sustainable building solutions, exemplified by Johnson Controls International PLC's investment in the International WELL Building Institute (IWBI). This strategic alliance emphasizes Johnson Controls' heightened dedication to providing solutions promoting healthy and sustainable building environments. In April 2023, Johnson Controls International PLC, headquartered in Ireland and known for manufacturing dedicated outdoor air systems, announced its investment in the International WELL Building Institute (IWBI). Through this partnership, Johnson Controls aims to leverage the WELL Enterprise Provider (EP) credential, assisting clients in fulfilling diverse business objectives encompassing ESG reporting, human and social capital management, and workplace planning and policies. As a WELL EP, Johnson Controls will expand its existing suite of building certification consulting services to encompass WELL certification and ratings, thereby fostering healthier and more conducive built environments. The International WELL Building Institute, based in the US, specializes in assessing, certifying, and monitoring built-environment aspects affecting human health and well-being.

In June 2024, Honeywell, a US-based technology and manufacturing company, acquired Carrier Global Corporation's Global Access Solutions Business for $4.95 billion. This acquisition strengthens Honeywell's position as a leading provider of digital security solutions and enhances its Building Automation segment. Carrier Global, also based in the US, specializes in providing dedicated outdoor air systems (DOAS) among its range of offerings. Through this acquisition, Honeywell aims to expand its capabilities and market presence in the building automation and security sectors.

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.
