Energy efficiency is framed as a health tradeoff when ventilation, humidity control, and filtration are not addressed. The source does not reject energy efficiency itself, only efficiency pursued without adequate indoor-air controls. Modern tighter construction is criticized for reducing fresh-air exchange. Spray-foamed attics with limited ventilation can accumulate humidity as warm humid air rises. Airtight homes can trap humidity and contaminants indoors.
