Architects, as the primary designers of our built environment, hold a profoundly influential position in shaping the health and well-being of building occupants. Beyond the critical considerations of aesthetics, structural integrity, and energy performance, a deep understanding of the invisible forces at play within a building's envelope is increasingly paramount. This report aims to equip architects with the essential knowledge to proactively design for superior indoor air quality (IAQ), particularly concerning emissions from common household gas appliances. The decisions made during the design phase, from material selection to mechanical system integration, directly influence the indoor environment and, by extension, the health outcomes of those who inhabit these spaces. This effectively positions architects as critical guardians of public well-being within the built space, expanding their traditional role to encompass a vital public health responsibility.
Read MoreThe United States faces a significant, yet largely unregulated, public health challenge: the quality of the air inside its buildings. 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.
