It may simply be that the air con is working hard .

I think you're confusing voltage with current Phil. The charging voltage should be relatively constant, it's the alternator's current delivery which changes depending upon the vehicle's demands.

As I said Pete, 14.5 volts is acceptable but it's not normal. I'd suggest that you activate the IPK diagnostics before a journey and monitor the charging voltage. Does it vary depending upon engine speed and/or heavy current demand?
