Dedicated Outdoor Air Systems (DOAS)Segmentation

The greater-than-60-ton capacity segment is growing fastest because large commercial, industrial, and institutional buildings increasingly require high-capacity systems to deliver consistent airflow, temperature control, and air quality management across complex, high-occupancy spaces.

Across various regions and industries, large buildings such as hospitals, airports, manufacturing plants, universities, data centers, and office complexes have grown in both size and operational complexity, requiring ventilation systems capable of handling substantial volumes of outdoor air efficiently. High-capacity DOAS units meet these demands by providing centralized control of airflow, temperature, and humidity while integrating with energy recovery and smart control technologies. Using a single large unit instead of multiple smaller units reduces installation complexity, lowers maintenance requirements, and optimizes space utilization in mechanical rooms, which is particularly important in dense urban areas or facilities with limited infrastructure. Industrial processes, including food processing, pharmaceuticals, and heavy manufacturing, generate high heat loads, moisture, and airborne particulates, all of which necessitate robust ventilation solutions. Additionally, high-capacity units allow operators to implement precise dehumidification, improve indoor air quality, and maintain stable environmental conditions for sensitive equipment and occupants. Seasonal climate variations, extreme weather conditions, and occupancy fluctuations further increase the need for systems that can reliably manage large air volumes without sacrificing energy efficiency or comfort. Facility managers also favor centralized, high-capacity systems because they simplify operations, reduce the number of moving components, and enable easier integration with building management systems. Overall, the growth of large-scale commercial and industrial infrastructure, combined with the need for operational efficiency, energy conservation, occupant safety, and regulatory compliance, makes the greater-than-60-ton segment the fastest-growing capacity category in the overall DOAS market.

New construction leads adoption because incorporating DOAS systems during the building design phase allows optimal performance, energy efficiency, and indoor air quality without the constraints or limitations of retrofitting existing structures.

Modern buildings are increasingly designed with sustainability, occupant comfort, and operational efficiency in mind. Installing DOAS units during construction ensures that ductwork, airflow distribution, and integration with HVAC and energy recovery systems are optimized from the start. Retrofitting older buildings often requires structural modifications, complex installation work, and compatibility adjustments, which increase cost and can compromise efficiency. New construction projects, whether commercial complexes, hospitals, schools, or industrial plants, provide flexibility in design and mechanical space allocation, allowing engineers to implement modular, scalable solutions that can accommodate future expansions or changing occupancy patterns. Facility owners benefit from lower operational disruptions and consistent air quality, while designers can incorporate smart controls and energy-efficient components to meet evolving regulatory requirements and sustainability certifications. Post-pandemic emphasis on health and indoor air quality further encourages builders to integrate advanced DOAS systems from the ground up. The combination of design flexibility, operational efficiency, regulatory compliance, and the ability to future-proof infrastructure ensures that new construction continues to be the fastest-growing implementation type for DOAS across the overall market.

New construction leads adoption because integrating DOAS systems during building design ensures optimal placement, efficient ductwork layout, and precise environmental control without the limitations of retrofitting older infrastructure.

In new projects, architects and engineers can plan mechanical rooms, ventilation shafts, and duct networks to maximize system performance, energy efficiency, and indoor air quality. Hospitals, commercial complexes, educational campuses, and industrial facilities increasingly incorporate DOAS from the outset to comply with modern energy standards, air quality regulations, and health guidelines. Retrofitting older buildings often involves structural modifications, space constraints, and compatibility issues with legacy HVAC systems, increasing costs and installation complexity. In contrast, new construction allows seamless integration of advanced features such as heat recovery, variable-speed fans, and smart building controls, enhancing both efficiency and occupant comfort. Post-pandemic emphasis on clean air, humidity management, and pathogen reduction further increases the preference for installing DOAS units during new construction. Large-scale and urban developments benefit from centralized, high-capacity systems designed to serve multiple zones efficiently, minimizing redundancy and energy waste. By incorporating these systems from the start, developers and facility managers ensure long-term reliability, lower operational disruptions, and compliance with environmental and health standards. The ability to optimize performance, reduce lifecycle costs, and provide a safe, comfortable indoor environment makes new construction the fastest-growing implementation type for DOAS in the overall market.

Dehumidification is growing fastest because controlling indoor humidity is essential for occupant comfort, health, building durability, and protection of sensitive equipment across diverse climates and building types.

Excess humidity can promote mold growth, structural degradation, corrosion of electrical and mechanical equipment, and discomfort for occupants. DOAS units address this by conditioning outdoor air separately from space cooling, allowing precise dehumidification without overcooling or wasting energy. High-occupancy buildings, such as offices, hospitals, schools, data centers, and industrial facilities, require consistent moisture control to maintain safe and healthy environments. Tropical, subtropical, coastal, and humid regions are particularly sensitive, but temperate climates also face seasonal humidity challenges. Advanced systems integrate heat recovery, variable-speed fans, and smart controls to optimize dehumidification while reducing energy consumption. Post-pandemic emphasis on indoor air quality and pathogen control has further accelerated demand for humidity management in public and commercial spaces. Facility managers and building owners rely on DOAS systems to maintain comfort, protect equipment and materials, and comply with indoor air quality standards. The combined need for health, comfort, structural protection, and operational efficiency ensures that dehumidification remains the fastest-growing service requirement for DOAS units in the overall market.
