Implementation in the Design Process:
In the program document, note any unusual water uses in the building for this occupancy class. As the site is selected, note any potential water intrusion potential associated with the site(s).
As the project proceeds through design, incorporate building envelope and mechanical systems to meet the performance criteria for I.2. Calculate dew points for interior surfaces of all exterior wall elements according to winter-day design conditions.
In bid documents, describe how materials at construction site are to be stored for protection against moisture damage during construction. Describe procedures to be followed to remove moisture-damaged materials from the construction site.
During construction, store materials appropriately to prevent water damage. Do not accept moisture sensitive materials with evidence of moisture damage, including stains. Remove them from the site and dispose of properly. Replace any moldy materials with new, undamaged materials. Sequence drying of construction materials appropriately during the construction process to prevent future problems.
During occupancy regular inspections should be conducted to ensure there are no visible signs of moisture intrusion or accumulation and to conduct regular testing of exterior wall construction to detect moisture in the exterior wall system. Remediation of identified exterior water intrusion should be corrected as soon as it is identified to lower the likelihood of mold growth.
