Buildings and Their Systems
Water management is important to prevent mold and mildew growth. All water and moisture must be diverted away the home via several methods:
During the BPI Field Exam, you should do a visual inspection around the perimeter of the house. One of the items you need to check for and mention to your BPI field proctor, is that you are looking for a slope the runs away from the home. This is to let stormwater, irrigation water, condensate water, water pumped from inside the house and any other source of moisture drain and go away from the house. If there is not a slope away from the house, moisture is likely to linger and can easily cause mold and mildew growth. If there is any neutral or ground that is sloped towards the home, we need to recommend fixing in our energy audit scope.
Plumbing should also be sloped to allow for naturally drainage, be free of leaks or use a pump circulate the water out and away from the home. Plumbing leaks may be found with a thermal camera within walls or the floor.
Gutters and the roof slope should allow bulk water to drain away from the home.
4. Sump pumps
Sump pumps should be used to pump water out and away from the home. They are used to remove water from condensate drains from the air handler unit in a basement and to overcome any positive elevation gain that natural drainage won't overcome.
