With air tight doors and windows, along with the construction of tighter homes sometimes there is not enough or proper airflow in a home creating condensation, mold, musty smells and moisture issues.
If your home has central AC, it is good practice to install additional vents that lead into your basement to help with minor moisture problems.
The air needs room to move, so if your basement is cluttered, an exhaust fan is good. However, you should also consider getting rid of some stuff. In addition to the moisture from a tight home, basements tend to be humid areas regardless. Because they are built below grade, the cool walls and the warm inside air create condensation as well.
Installing a dehumidifier can help with humidity in the basement. This is a very efficient way to remove the moisture from the air.
