To limit the potential for bacteria and mold growth within buildings from water infiltration and condensation.
Part 1: Exterior Liquid Water Management
A point-by-point narrative describes how liquid water from outside the building is addressed; responding to the nature and intensity of wetting based on the project's site and climate, and includes the following leading concerns:
- Site drainage, including the impact of any site irrigation.
- The local water table.
- Building penetrations (especially windows and plumbing/electrical/mechanical penetrations).
- Porous building materials connected to exterior sources of liquid water.
Part 2: Interior Liquid Water Management
A point-by-point narrative describes how liquid water from interior sources is addressed, including these leading concerns:
- Plumbing leaks.
- "Hardpiped" plumbing appliances (appliances such as clothes washers exposed to building water pressure even when not in use).
- Porous building materials connected to interior sources of liquid water.
- New building materials with “builtin” high moisture content or building materials wetted during construction but now on the inside of the building.
Part 3: Condensation Management
A point-by-point narrative describes how condensation is addressed, including these leading concerns:
- High interior relative humidity levels, particularly in susceptible areas like bath and laundry rooms and belowgrade spaces.
- Air leakage which could wet either exposed interior materials or interstitially “hidden” materials.
- Cooler surfaces, such as basement or slabon-grade floors, or closets/cabinets on exterior walls.
- Oversized air conditioning units.
Part 4: Material Selection and Protection
A point-by-point narrative describes how moisture-tolerant materials have been selected and/or moisture-sensitive materials (MSP) are being protected, considering these leading concerns:
- Exposed entryways and glazing.
- Porous cladding materials.
- Finished floors in potentially damp or wet rooms such as basements, bathrooms and kitchens.
- Interior sheathing in damp or wet rooms.
- Sealing and storing of absorptive materials during construction.
