ASHRAE Standard 160P-Criteria for Moisture Control Design Analysis in Buildings

In 1996, ASHRAE formed a new Standard Project Committee, ASHRAE 160P, to develop a standardfor moisture control in buildings. The draft standard __ "Criteria for Mois­ ture Control Design Analysis in Buildings" __ intends to provide performance-based procedures for moisture design analysis for buildings. The standard sets criteriafor moisture design loads, moisture analysis methods, and building perfor­ mance and applies to the above-grade portions of all types of buildings. It can be used for design analysis of the above-grade portion of the building envelope or help guide specifications for HVAC equipment and controls. Eventually it should form the basis for moisture design rules based on a uniform set of design assumptions and loads. This paper describes the ratio­ nale behind this standard, its current outline, and its potential uses.
