One site-built house was operated at ventilation rates from 0.14 to 0.78h-1. Several of the site-built houses had ventilation rates below the ASHRAE recommended value. Generally, the ratios of emission rates at the low and high ventilation rates decreased with decreasing compound volatility. Changes in VOC emission rates in the manufactured houses over 2-to-9.5 months after installation varied by compound. Only several compounds showed a consistent decrease in emission rate over this period.
