The global heating, ventilation, and air conditioning (HVAC) industry is undergoing a significant transformation driven by the phasedown of high-Global Warming Potential (GWP) refrigerants, primarily Hydrofluorocarbons (HFCs). This shift, mandated by international agreements like the Kigali Amendment and domestic legislation such as the U.S. American Innovation and Manufacturing (AIM) Act, presents both substantial challenges and unique opportunities for the Architecture, Engineering, and Construction (AEC) industry.

Americans spend approximately 90% of their time indoors , breathing air that can be two to five times, and occasionally more than 100 times, more polluted than outdoor air. Despite this reality, the nation lacks a comprehensive federal code specifically governing indoor air quality (IAQ), relying instead on a fragmented system of state regulations, voluntary guidelines, and limited occupational standards. This regulatory gap results in inconsistent protection and contributes to a silent epidemic of health problems—ranging from asthma and allergies to cardiovascular disease, cognitive impairment, and cancer—and imposes a substantial economic burden through healthcare costs and lost productivity, estimated in the tens to hundreds of billions of dollars annually.
