Think about moisture sources
Wet garden tools, outdoor equipment and changing temperatures can introduce moisture. Air movement can be one part of a broader moisture management strategy.
Do not block planned airflow
Insulation, stored items and interior finishes can interfere with vents if they are added without considering the ventilation path.
Match ventilation to the building
A basic storage shed and a conditioned workshop have different needs. If the shed will be insulated, heated or cooled, use a building assembly appropriate for your climate and intended use.
