Global market valuation was derived through revenue mapping and equipment shipment volume analysis. The methodology included:
Identification of 50+ key manufacturers across North America, Europe, Asia-Pacific, Latin America, and Middle East & Africa
Product mapping across packaged rooftop units, modular AHUs, custom-built units, and specialized configurations (low profile, rooftop-mounted)
Analysis of reported and modeled annual revenues specific to air handling unit portfolios, including aftermarket components (filters, coils, controls)
Coverage of manufacturers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (building floor area additions × HVAC load factors × AHU specification rates by country) and top-down (manufacturer revenue validation against AHRI/Eurovent certification databases) approaches to derive segment-specific valuations for single-effect versus double-effect heat recovery systems and capacity-based market splits
