Ventilation, Humidity and Condensation in Manufactured Houses during Winter

摘要

Manufactured houses often have low natural ventilation rates, often lower thenthe average site-built houses. Without additional mechanical ventilation to supplement natural ventilation many manufactured houses do not meet the current ASHRAE 62-1989 minimum ventilation standard. Insufficient ventilation may lead to moisture damage, high humidity, and other indoor air quality problems. This study presents measured data on ventilation and moisture behavior of manufactured houses as well as moisture release from occupants and other sources.
