Weather-stripping of doors, including sweeps on the bottom, is one of the most cost-effective energy conservation measures.  However, no weatherstrip lasts forever and life expectancy is especially short around high-use doors.  So only commercial grade products should be used, and replacement should be a regular maintenance item (generally every one or two years in high traffic doorways).

The following doors should be taken care of as soon as possible:
