Small soil temperature increases cause large indoor air VOC concentration increases. Measure indoor air VOC concentration after a 2 kPa decrease in barometric pressure. Soil temperature controls diffusion rates by controlling concentration gradients. Building ventilation is critical in controlling indoor air VOC concentrations.
