Executive Snapshot and Market Trajectory

Indoor air quality scrutiny, not energy cost alone, is now the primary trigger for dedicated outdoor air system specification, and building owners who decoupled ventilation from space conditioning two design cycles ago are avoiding the mould and humidity complaints still plaguing conventional rooftop unit installations today.
China's commercial construction volume now generates more new DOAS installations annually than any other market, pulling energy recovery ventilator demand toward Asian manufacturers even as Trane, Daikin, and Carrier compete for the same North American retrofit contracts. DOAS controls and IAQ monitoring systems are the fastest-growing product class, still smaller than core air-handling hardware today but critical to the real-time air quality verification that building codes increasingly require occupants to see displayed.
Five suppliers, Trane Technologies, Daikin Applied, Carrier Global, Johnson Controls, and Lennox International, hold roughly 48 percent of global dedicated outdoor air system revenue, a concentration built on decades of air-handling engineering that newer entrants cannot easily replicate. ASHRAE 62.1 ventilation requirements and state-level energy recovery mandates are pulling DOAS specification forward on building design schedules nationwide well beyond what energy cost savings alone would have funded.
Market Definition
The dedicated outdoor air system market covers packaged and split DOAS units, energy recovery ventilators, and associated controls that condition and deliver 100 percent outdoor ventilation air separately from a building's space conditioning system. It excludes conventional rooftop units that mix ventilation and recirculated air, standalone exhaust fans, and residential-scale ventilation equipment.

Dedicated Outdoor Air System Market Forecast Scenarios

dedicated-outdoor-air-system-market-size-forecast-scenario-1787300010991
Dedicated outdoor air system demand grew steadily from 2020 through 2025 as post-pandemic indoor air quality concerns pushed building owners to reconsider ventilation design across offices, schools, and healthcare facilities. Energy recovery mandates accelerated adoption only after several states updated commercial energy codes, and the segment grew at roughly a 6.8 percent historical compound rate.
MMA's base case assumes 7.8 percent compound growth through 2036, anchored in three mechanisms. First, ASHRAE 62.1 ventilation standards and state energy codes are making energy recovery DOAS the default specification for new commercial construction. Second, China and India's commercial construction volume is generating a steady stream of greenfield DOAS installations independent of the North American retrofit cycle. Third, IAQ monitoring and controls adoption is pulling building owners toward systems that can verify ventilation performance in real time rather than assuming compliance.
A bull scenario near 9.1 percent follows if additional US states and EU member countries adopt binding energy recovery mandates ahead of the current regulatory timeline. The bear case near 6.5 percent materialises if commercial construction spending slows enough that building owners defer decoupled ventilation upgrades, extending conventional rooftop unit replacement cycles longer than currently expected.

Ventilation Decoupling Reshapes Commercial HVAC Design

Dedicated outdoor air systems have moved from a specialised engineering choice into a mainstream design default almost overnight, and that shift is reshaping how mechanical engineers approach commercial building HVAC layouts. Buildings that would have used conventional mixed-air rooftop units for another design generation are now specifying decoupled ventilation early because indoor air quality complaints and energy code compliance risk have become harder for owners to ignore than the incrementa

Commercial activity concentrates in energy recovery ventilators and packaged DOAS units, where proprietary heat exchanger technology and application engineering give the five largest suppliers durable technical advantages. DOAS controls and IAQ monitoring systems remain a smaller but fast-scaling category, increasingly specified directly by building owners and code officials rather than left to contractors to recommend after occupancy complaints emerge.
The next decade will be shaped less by air-handling hardware innovation than by how fast controls and monitoring technology can verify ventilation performance that used to be assumed rather than measured. Suppliers that can bundle hardware with credible real-time IAQ verification capture disproportionate share of the specification decisions building owners now make.

Market Trends

ASHRAE Energy Recovery Mandates Reshape New Construction Specification

Updated ASHRAE 90.1 energy standards and state-level commercial energy codes require energy recovery ventilation on new construction above defined outdoor air thresholds, making decoupled DOAS the default rather than a value-engineered option engineers can eliminate late in design. Building owners in states that adopted the most recent code cycle report that DOAS specification happens automatically during schematic design rather than as a late-stage energy modelling exercise. Trane and Daikin Applied both report that code-driven specification, not owner-requested savings, is the primary justification cited in new commercial proposals, a shift from a decade of value-engineering conversations that dominated commercial HVAC procurement.
Market Impact: Adds $1.4B in greenfield project orders

IAQ Monitoring Adoption Bundles Controls Into Base Specifications

Building owners and tenants increasingly require real-time indoor air quality monitoring displayed to occupants, rather than assuming compliance based on design documentation alone, pulling DOAS controls and monitoring hardware into base project specifications instead of treating them as an optional add-on. Johnson Controls and Carrier have both restructured their commercial offerings around this bundled model, since customers report that visible IAQ verification has become a leasing and tenant retention consideration in competitive commercial real estate markets. Suppliers without credible native monitoring capability are increasingly losing bundled specifications to competitors that can deliver hardware and verification from a single vendor relationship.
Market Impact: Sustains a 37% retrofit demand share

Market Opportunities and Growth Drivers

Commercial Construction Growth in China and India Drives Greenfield Demand

China's commercial and institutional construction volume, particularly schools and healthcare facilities under updated national ventilation standards, is generating a steady pipeline of greenfield DOAS installations independent of the North American retrofit-driven replacement cycle. Daikin and domestic Chinese manufacturers are commissioning new energy recovery ventilator production capacity at a pace that has kept Asian order books growing even as North American and European retrofit spending remains a larger absolute revenue pool today. This geographic split is shifting where suppliers concentrate engineering headcount and assembly capacity, favouring manufacturers already established in Chinese and Indian supply chains over newer entrants without regional relationships.
Market Impact: Adds 15-25% cost versus conventional units

Post-Pandemic IAQ Awareness Sustains Retrofit Demand

Building owners and facility managers retain heightened sensitivity to indoor air quality following the pandemic, sustaining retrofit demand for decoupled ventilation well beyond what would have been expected from energy code compliance pressure alone. Schools and healthcare facilities have moved fastest on retrofit projects, since their occupant populations are considered most vulnerable and their funding often ties directly to documented air quality improvements under grant programmes. Office and hospitality retrofit demand has proven more cyclical, tracking occupancy recovery and capital budget availability more closely than the steadier institutional retrofit segment specifically.
Market Impact: Extends design timelines by roughly 20%

Market Restraints and Challenges

Higher First Cost Slows Value-Tier Project Adoption

Dedicated outdoor air systems with energy recovery cost more upfront than conventional mixed-air rooftop units, and the root cause lies in the equipment itself: heat exchanger cores, dedicated fans, and enhanced controls add hardware complexity that conventional single-package units do not carry. That first-cost gap slows adoption in price-sensitive project types like speculative office and budget-constrained public construction, even as institutional and premium commercial projects convert readily. Suppliers including Greenheck and AAON are mitigating the gap by developing simplified, lower-cost DOAS product lines targeting price-sensitive project types, narrowing the addressable gap between DOAS and conventional equipment.
Market Impact: Adds 8pp to code-mandated specification volume

Design and Commissioning Complexity Extends Project Timelines

Decoupled DOAS design requires mechanical engineers to coordinate ventilation loads, humidity control, and space conditioning across two separate systems rather than one rooftop unit, and the root cause is engineering complexity: getting the interaction between systems right requires expertise that not every design firm has developed. That complexity extends design and commissioning timelines relative to conventional single-package equipment, on projects where the design team has limited prior DOAS experience. Suppliers including Trane and Semco are mitigating the gap by offering pre-engineered application guides and commissioning support designed to shorten the learning curve for design teams new to decoupled ventilation.
Market Impact: Lifts controls attach rate to 41%

Segment CAGR and Growth Architecture

MMA segments the dedicated outdoor air system market by product type, the classification mechanical engineers actually specify and schedule against, rather than by building type or capacity range alone. Six product types cover the addressable market, each with distinct heat exchanger technology, controls integration, and application engineering requirements across commercial, institutional, and healthcare construction.
dedicated-outdoor-air-system-market-market-share-analysis-1787300011560

DOAS Controls and IAQ Monitoring Systems

DOAS controls and IAQ monitoring systems are growing fastest because building owners and tenants increasingly require real-time verification of ventilation performance rather than relying on design documentation alone to confirm code compliance. Johnson Controls and Carrier both dominate this segment given their building automation platform integration and the software development investment that newer entrants find difficult to replicate. Deployment complexity remains a constraint, since integrating IAQ monitoring with existing building automation systems requires coordination that not every project team has budgeted for. Growth here is expected to broaden as monitoring hardware costs decline and tenant lease agreements increasingly reference documented air quality performance as a standard commercial term rather than a premium building feature reserved for trophy office space.
CAGR 10.8%

Air-to-Air Energy Recovery DOAS Units

Air-to-air energy recovery DOAS units are the second-fastest-growing product type as ASHRAE 90.1 energy standards and state-level commercial energy codes mandate recovery on new construction projects above defined outdoor air thresholds. Trane and Daikin Applied both dominate this segment given their heat exchanger core technology and the application engineering track record that newer entrants find difficult to match at comparable efficiency. Fabrication capacity in Asia is scaling quickly to serve this segment, since heat exchanger core manufacturing benefits from the same precision assembly infrastructure supporting the region's broader HVAC component production. Growth here tracks with how aggressively energy codes tighten, since code stringency is the single biggest driver of whether energy recovery becomes mandatory or remains a value-engineered option.

Regional Architecture and Country Demand Map

East Asia leads dedicated outdoor air system demand as China's commercial and institutional construction volume outpaces the rest of the world combined, while North America retains the deepest installed base and most mature energy code enforcement. South Asia and Pacific is scaling fastest behind India's rapid commercial construction growth.

North America

The United States' commercial construction sector anchors North American demand through a mix of energy-code-driven new construction specification and post-pandemic retrofit demand across schools, healthcare facilities, and office buildings. Trane and Johnson Controls both maintain their largest engineering and manufacturing footprints domestically, giving North American building owners faster access to application engineering support than importing equipment from overseas suppliers would allow. Canadian provincial energy codes are converging toward similar energy recovery requirements as US states, while Mexican commercial construction growth tied to nearshoring trends is gradually building demand for decoupled ventilation equipment in newly built industrial parks and supporting office facilities serving the broader North American market. California's Title 24 energy code has moved earliest toward mandatory recovery statewide.
Share: 26% | CAGR: 7.8% (2026 to 2036)

Western Europe

Germany and the UK anchor Western European demand, both having implemented building energy performance requirements that increasingly favour decoupled ventilation with energy recovery over conventional mixed-air systems in new commercial construction. The EU's Energy Performance of Buildings Directive applies broadly across member states, giving Swegon and Systemair's European manufacturing operations a large, relatively homogeneous specification market to serve compared with the more fragmented regulatory landscape in other regions. The Nordic region's building stock, already accustomed to mechanical ventilation with heat recovery in residential construction, extends that expectation naturally into commercial buildings, giving Nordic building owners some of the highest energy recovery attach rates recorded anywhere globally. France's newer building energy regulations are pushing similar recovery requirements into non-residential construction nationwide.

Controls Bundling and Retrofit Service Premiums

Suppliers extract value less through packaged unit pricing than through bundling IAQ controls and monitoring into base specifications, capturing recurring service and verification revenue, and winning greenfield capacity contracts in Asia ahead of competitors. The levers below describe how each part of the value chain captures its share of the ventilation decoupling wave now underway across commercial construction.

Controls Bundling Captures Recurring Verification Revenue

Suppliers are structuring DOAS contracts to include IAQ monitoring hardware and verification software rather than selling equipment and controls separately, converting a portion of what was once one-time capital revenue into recurring subscription-like revenue. Johnson Controls and Carrier both report that bundled controls attach rates have risen from roughly 25 percent to 41 percent over the past three years, since building owners evaluate ongoing verification capability as a leasing consideration rather than a discretionary add-on. This bundling deepens switching costs, since replacing a DOAS now means replacing a whole monitoring platform, not just the hardware.
Market Impact: Lifts recurring controls revenue by roughly 12-16pp share

Application Engineering Services Command Premium Fees

Suppliers offering application engineering support, including load calculation and commissioning oversight, charge 15 to 20 percent more than for equivalent hardware sold without engineering support, since design teams new to decoupled ventilation need expert guidance to avoid costly commissioning failures. Trane has built an application engineering practice to capture this premium, recognising that engineering work carries higher margins than hardware installation given its lower capital intensity. Design teams facing unfamiliar decoupled ventilation requirements are willing to pay this premium rather than risk a failed commissioning process, giving suppliers pricing power in a service category that barely existed a decade ago.
Market Impact: Commands a 15-20% pricing premium for engineering support services

Greenfield Asian Contracts Anchor Multi-Year Revenue

Suppliers that win greenfield DOAS contracts for new commercial and institutional construction in China and India secure not just the initial hardware sale but 10-plus years of follow-on filter, controls, and maintenance revenue as the building operates through its service life. Daikin and Trane have both prioritised Asian greenfield relationships specifically because these contracts anchor multi-year customer relationships in markets where construction volume continues at a pace North American and European retrofit spending cannot match. Suppliers without an established Asian manufacturing presence find it increasingly difficult to compete for this anchor business regardless of technical capability.
Market Impact: Anchors 10-plus years of recurring follow-on service revenue

Retrofit Compliance Deadlines Create Urgent Switching Windows

Suppliers positioned to support building owners facing tenant lease renewal negotiations tied to documented indoor air quality performance capture urgent, less price-sensitive retrofit projects that carry meaningfully better terms than routine competitive bidding cycles. Suppliers including Carrier and Munters have both built rapid-response retrofit teams specifically to serve building owners under leasing time pressure, recognising that speed matters more than price in these urgent switching situations. Building owners facing an imminent lease renewal typically pay a premium of roughly 10 to 15 percent above standard project pricing in exchange for accelerated installation and guaranteed capacity allocation ahead of tenant negotiations.
Market Impact: Commands a 10-15% premium on urgent retrofit projects

Who Controls the Margin Pool

Five suppliers, Trane Technologies, Daikin Applied, Carrier Global, Johnson Controls, and Lennox International, hold roughly 48 percent of global dedicated outdoor air system revenue, a concentration built on decades of air-handling engineering and heat exchanger investment. The gap to challengers like Munters and Greenheck narrows in specialty formats, high-humidity dehumidification applications, where application engineering matters less than in standard commercial energy recovery production.
Current competitive activity centres on three fronts: bundling IAQ monitoring and controls into base specifications to capture recurring revenue, building application engineering services to capture the premium that decoupled design complexity commands, and racing for greenfield capacity contracts across China and India that anchor years of follow-on business. Suppliers are investing in simplified, lower-cost product lines to narrow the first-cost gap with conventional rooftop units.

Emerging pressure comes from Chinese manufacturers expanding energy recovery ventilator capacity to serve domestic construction demand, competing on speed and cost for standard applications rather than premium engineered systems. Rankings are most likely to shift in controls and monitoring, where software integration capability rather than raw manufacturing capacity determines competitive position, leaving room for suppliers that move fastest on IAQ verification technology to gain share from slower-moving incumbents.

Competitive Moat and Risk Dimensions

TRANE TECHNOLOGIES

Moat: Deep Application Engineering Track Record

Trane has supported more complex decoupled ventilation projects across more building types than most rivals, giving design teams a trusted resource for humidity control and load calculation challenges that newer entrants have not yet encountered at comparable scale. That accumulated engineering expertise, built over decades of commercial project experience, is difficult for competitors to replicate quickly.
TRANE TECHNOLOGIES

Risk: Cost Disadvantage Versus Asian Rivals

Trane's North American and European manufacturing footprint carries higher labour costs than Asian manufacturers now qualifying comparable energy recovery capacity, leaving Trane more exposed to cost-based competition in standard, less differentiated applications. If Asian manufacturers keep closing the quality gap in commodity DOAS equipment, Trane's cost disadvantage could narrow its addressable share in that segment.
DAIKIN APPLIED

Moat: Integrated Asian Manufacturing Scale

Daikin's ownership of extensive Asian manufacturing capacity gives it direct cost and delivery advantages serving China and India's rapidly growing commercial construction demand that competitors relying on imported equipment cannot match, providing a durable regional cost and supply-security advantage. That regional footprint is difficult and capital-intensive for import-dependent competitors to replicate quickly.
DAIKIN APPLIED

Risk: Slower North American Brand Recognition

Daikin Applied has built North American brand recognition more slowly than domestic incumbents like Trane and Carrier, leaving it comparatively less positioned to win specification battles where engineers default to familiar established brands. Closing that gap will require sustained marketing and relationship investment that Daikin has only recently begun prioritising domestically.

Daikin commissioned expanded energy recovery ventilator manufacturing capacity in China in June 2025, adding dedicated production lines to serve the country's rapidly growing commercial and institutional construction demand. The expansion positions Daikin to capture growing greenfield specification demand from developers entering the regional market this cycle.
Signal: Marks continued investment in Asian manufacturing capacity as demand keeps shifting toward the region's construction volume.

Steel and Refrigerant Cost Exposure

Galvanized steel and aluminum casing and heat exchanger core materials represent a significant cost input for dedicated outdoor air systems, accounting for roughly 34 percent of finished unit cost, sourced from a global metals market subject to trade tariff volatility. Refrigerant costs for direct-expansion cooling coils add meaningful secondary exposure, particularly as regulatory phase-downs of high-global-warming-potential refrigerants push manufacturers toward newer, more expensive alternati
Steel and aluminum tariffs implemented in 2025 disrupted commercial HVAC equipment cost structures industry-wide, and Trane Technologies' fiscal year 2025 annual report cited elevated raw material costs as a meaningful drag on segment margins despite strong underlying construction demand. Manufacturers responded by qualifying additional domestic steel suppliers and redesigning some casing components to use less material per unit, reducing exposure to tariff volatility that had previously represented an unhedged cost risk across the industry.

Vertically integrated suppliers with domestic manufacturing capacity, including Trane and Johnson Controls, absorbed tariff-driven cost increases more predictably than manufacturers dependent on imported components and finished assemblies from overseas facilities. That gap gives domestically integrated suppliers a durable cost-stability advantage over smaller specialty manufacturers, particularly during trade policy disruptions that periodically squeeze margins across the broader commercial HVAC industry.
dedicated-outdoor-air-system-market-cost-volatility-analysis-1787300012798

Domestic Steel Sourcing to Reduce Tariff Exposure

Leading manufacturers are qualifying additional domestic steel and aluminum suppliers to reduce dependence on imported metals subject to tariff volatility, protecting cost predictability during periods of trade policy disruption. This approach adds qualification cost and complexity but meaningfully reduces exposure to tariff changes that periodically squeeze manufacturer margins across the broader commercial HVAC industry.

Material-Efficient Casing Redesign to Cut Steel Content

Manufacturers are redesigning unit casings to use less steel and aluminum per unit without compromising structural performance, trading some design flexibility for meaningfully reduced material cost exposure. This redesign work requires upfront engineering investment but reduces long-term exposure to metals price volatility. Smaller manufacturers without dedicated engineering resources adopt this approach more slowly than larger rivals.

Long-Term Refrigerant Supply Agreements With Producers

Larger manufacturers are signing multi-year refrigerant supply agreements directly with chemical producers to secure priority allocation and pricing certainty ahead of regulatory phase-down deadlines, an option generally unavailable to smaller manufacturers without comparable purchasing scale. This advantage reinforces existing market concentration, since guaranteed refrigerant access increasingly determines which suppliers can reliably fulfil large commercial contracts on schedule.

Portfolio Architecture for Margin Defence

Dedicated outdoor air system suppliers operate across three margin tiers built around engineering complexity and controls content rather than simple unit volume. Commodity-adjacent standard packaged units sit at the volume base, energy recovery units and application-engineered systems occupy the middle at meaningfully firmer margins, and IAQ monitoring platforms and premium application engineering services sit at the top, commanding premium pricing that few standard equipment manufacturers can c
The volume-premium tension plays out most visibly in how suppliers allocate scarce application engineering talent: every hour spent supporting a standard packaged unit specification is an hour not spent on higher-margin energy recovery design work, so suppliers increasingly prioritise complex projects even when it means ceding standard unit volume to regional competitors willing to compete purely on price.

High-value margin pools concentrate in IAQ monitoring platforms and application engineering services for complex decoupled ventilation designs, both of which command pricing closer to specialised professional services economics than to commodity air-handling manufacturing. Suppliers that can move a customer from standard packaged unit supply into a bundled controls-and-engineering relationship capture meaningfully more of total account value.

Volume / Commodity-Adjacent Tier

Standard packaged DOAS units without energy recovery sold at scale into routine ventilation applications, priced close to established manufacturing benchmarks with limited technical differentiation. This tier competes mainly on delivery lead time and price.
Gross Margin: 14-20%

Premium / Certified Tier

Energy recovery DOAS units and application-engineered systems requiring load calculation and humidity control expertise, commanding a defensible premium given the engineering investment behind each specified system. Buyers weigh application track record heavily.
Gross Margin: 22-30%

Sustainability / Regulatory / Next-Generation Tier

IAQ monitoring platforms and premium application engineering services carrying the deepest technical support and software development investment, sold primarily into building owners' highest-visibility tenant retention programmes. Pricing power here remains strong.
Gross Margin: 32-42%
dedicated-outdoor-air-system-market-portfolio-architecture-1787300013300

High-value Sub-segments and Strategic Watch-out

IAQ Monitoring and Verification Platforms

IAQ monitoring platforms carry the category's highest margins and fastest growth, driven by tenants and building owners seeking documented, real-time air quality verification that goes beyond code compliance toward genuine leasing differentiation across premium office and healthcare categories. Early movers here are capturing outsized specification share.
Gross Margin: 32-42%

Energy Recovery DOAS Units

Energy recovery DOAS units carry strong margins and steady growth, anchored in code-mandated specification relationships that renew predictably as building owners expand energy recovery adoption across additional facility portfolios and building types. Renewal rates remain unusually high once a code-mandated specification is first firmly established.
Gross Margin: 26-34%

Standard Packaged DOAS Units

Standard packaged units without energy recovery remain the category's volume anchor, growing steadily with overall commercial construction output but carrying commodity-level margins that make it a scale rather than profit driver for most suppliers. Suppliers defend this tier mainly to preserve distribution reach and factory utilisation.
Gross Margin: 14-20%

Asian Manufacturing Capacity

Regional Asian manufacturers expanding energy recovery ventilator capacity represent a long-term competitive threat to established suppliers' pricing power, particularly as domestic Chinese and Indian developers increasingly favour lower-cost regional suppliers over premium Western incumbents. European suppliers slow to respond risk ceding meaningful volume region-wide over time.
Gross Margin: 16-24%

From Value-Engineered Option to Design Default

Dedicated outdoor air system specification is shifting from a value-engineered option decided late in project design toward an early design-stage default that resembles an ongoing application engineering partnership more than a series of one-time equipment purchase transactions. Suppliers that embed application engineering support into project teams early lock in specification influence, while mechanical engineers increasingly treat decoupled ventilation as the starting assumption for new commer
Adoption depth varies sharply by building type. Healthcare and institutional facilities show the deepest reliance on decoupled ventilation, since their occupant populations and regulatory scrutiny demand the highest air quality standards available. Speculative office and budget-constrained public construction show shallower, more cost-driven adoption, specifying energy recovery primarily when code requires it rather than proactively ahead of any binding mandate.

A generational shift among mechanical engineering teams is reinforcing the trend. Younger engineers trained during the recent IAQ awareness wave treat decoupled ventilation as standard practice, while veteran teams accustomed to conventional rooftop unit specification are adapting more slowly, occasionally defaulting to familiar equipment until forced by code requirements or client demand.

Where MMA Sees the Real Opportunity

These are among the four positions where our research anticipates prominent divergence between winners and laggards over the coming forecast period. Each is grounded in the demand model, the regulatory perimeter, and the announced capacity pipeline.
01 / CONTROLS BUNDLING PRIORITY

Bundle IAQ monitoring into every base specification now

Suppliers that bundle IAQ monitoring and controls into base DOAS specifications are capturing recurring verification revenue that pure hardware competitors cannot match, and building owners treat visible air quality verification as a leasing consideration rather than a discretionary add-on. This positioning matters more than competing on packaged unit pricing, since controls capability, not air-handling specifications alone, determines which supplier wins premium commercial contracts. MMA recommends prioritising controls bundling investment over incremental hardware feature development in the current three-year window, for suppliers serving premium office and healthcare segments.
02 / APPLICATION ENGINEERING SERVICES

Build dedicated application engineering practice capability

Application engineering services command meaningfully higher margins than standard hardware installation, and suppliers with a credible dedicated engineering practice are winning premium project specifications at rates competitors relying purely on product quality cannot match. Suppliers still treating engineering support as a free value-add rather than a priced service are leaving meaningful margin on the table relative to competitors already monetising this capability directly. MMA views dedicated application engineering investment as the highest-return near-term opportunity available within the category over the next three years.
03 / ASIAN CAPACITY INVESTMENT

Build manufacturing capacity in China and India now

China and India together generate more dedicated outdoor air system demand growth than any other region, and suppliers without meaningful Asian manufacturing capacity face a genuinely difficult path to capturing this volume regardless of North American engineering leadership or brand relationships. Regional Asian manufacturers are closing the quality gap in standard energy recovery equipment faster than expected, narrowing the window for established suppliers to establish a durable regional position. MMA recommends prioritising Asian capacity investment ahead of competitors still weighing whether the region merits dedicated manufacturing commitment.
04 / RETROFIT PRODUCT DEVELOPMENT

Develop compact retrofit-specific product lines now

Retrofit demand represents a meaningfully steadier revenue base than new construction, which tracks commercial development cycles more closely, yet many suppliers still offer only new-construction-oriented product lines poorly suited to existing buildings' space and structural constraints. Trane's recent compact retrofit product launch demonstrates that dedicated retrofit engineering can capture demand that generic new-construction products leave unaddressed in space-constrained existing buildings. MMA recommends prioritising retrofit-specific product development as a durable, less cyclical revenue diversification strategy for suppliers overexposed to new construction volume.

MARKET MINDS ADVISORY · CLIENT ENGAGEMENT SUMMARY
Dedicated Outdoor Air System Producer Strategic Portfolio Review and Transition Roadmap 2026·Investment Scenario on Dedicated Outdoor Air System Exposure Evaluation 2025-26
CLIENT PROFILE
The client is a regional healthcare system operating twelve facilities across three states, running a mix of conventional rooftop units and ageing DOAS installations facing updated healthcare facility ventilation standards. The system reported annual facilities capital budgets in the low hundreds of millions of dollars (client-reported, unverified by MMA) and had not yet developed a system-wide prioritisation strategy for ventilation upgrades across its full facility portfolio.
STRATEGIC CHALLENGE
The client faced updated ventilation compliance deadlines across all twelve facilities simultaneously, but capital and engineering resources meant a phased approach was unavoidable, requiring a defensible framework for sequencing facility upgrades. Management needed a strategy that balanced compliance risk, patient population vulnerability, and available capital across a multi-year upgrade programme without disrupting ongoing clinical operations at any single facility.
MMA APPROACH
MMA's engagement team assessed ventilation compliance exposure, patient population risk, and existing equipment condition across all twelve facilities, interviewed the client's regulatory affairs team to clarify compliance deadline flexibility, and modelled upgrade cost and clinical disruption risk across three sequencing scenarios. The team recommended a risk-weighted prioritisation framework that sequenced upgrades by combined compliance exposure and patient population vulnerability rather than by simple equipment age.
KEY FINDINGS
  1. Regulators indicated willingness to extend compliance deadlines for facilities with documented interim mitigation measures (client-reported, unverified by MMA), reducing pressure to upgrade all twelve facilities simultaneously.
  2. The facility with the oldest equipment was not the facility with the highest compliance exposure, since patient population vulnerability mattered more than equipment age in the client's actual risk profile.
  3. Bundling IAQ monitoring into the equipment upgrade contract reduced total programme cost compared with procuring monitoring separately after each facility's hardware upgrade.
  4. Clinical operations scheduling, not capital availability, was the client's binding constraint on how many facilities could be upgraded simultaneously within the compliance window.

  2. The facility with the oldest equipment was not the facility with the highest compliance exposure, since patient population vulnerability mattered more than equipment age in the client's actual risk profile.
  3. Bundling IAQ monitoring into the equipment upgrade contract reduced total programme cost compared with procuring monitoring separately after each facility's hardware upgrade.
  4. Clinical operations scheduling, not capital availability, was the client's binding constraint on how many facilities could be upgraded simultaneously within the compliance window.
RECOMMENDED STRATEGY
Phase 1: Phase 1 (Months 1 to 8): Upgrade the three highest patient-risk facilities first, securing regulator-documented interim mitigation for the remaining nine sites. Phase 2: Phase 2 (Months 9 to 20): Sequence the remaining nine upgrades by combined patient risk and exposure, bundling IAQ monitoring into each equipment contract. Phase 3: Phase 3 (Months 21 to 32): Complete the final facility upgrades and consolidate all twelve sites onto a unified monitoring and compliance documentation platform.
OUTCOME
Following the engagement, the client reported completing its twelve-facility upgrade programme within the extended compliance window while avoiding the clinical disruption risk of simultaneous upgrades (client-reported, unverified by MMA). Bundled IAQ monitoring reduced programme cost relative to the client's original budget, and the unified compliance platform simplified ongoing regulatory reporting across all twelve facilities.
