Keep your effort below the sweat threshold on the way there. Think walking-effort, not running-effort.

Bikes are about 4x more efficient, so for short and moderate distances, even walking-effort will get you there in reasonable time.

If you sweat at a walking-effort, try dressing lighter or as others have suggested, use wet wipes and spare clothes at work.

You can also consider an e-bike to avoid sweating on the way to work. On the commute home, use less assist if you want more exercise.
