Moisture control problems account for up to 80 percent of all associated premature wear expenditures made on built facilities. Although proper commissioning procedures have been noted to reduce the potential for approximately 70 percent of these claims, no standards exist for the control of moisture migration in building commissioning guidelines. The development of commissioning guidelines for the control of moisture migration involves quantifying, with a risk management approach, the performance thresholds that distinguish acceptable from unacceptable design. These criteria should define allowable threshold values regarding mold growth, corrosion, loss of structural strength, and indoor air quality. This report includes an introduction and brief history of building commissioning and the code regulations intended to address moisture in buildings, a description of the commissioning process as related to the building envelope in humidified buildings, and discussions of building humidification and the criteria and guidelines for commissioning humidified buildings. The guidelines explain the role of a building envelope commissioning agent, from early in the design phase, through construction, to assuring proper operation after occupancy. This process includes the use of performance modeling techniques to predict the envelope performance prior to completion.
