How to calculate weather impact on control unlagged to head.
(OP)
Dear All,
I am looking for a rule of tumb to calculate if a dont lag (insulate) the top section of a column what the impact on performance would be ?
I am basically looking for a rule of thumb calculation.

The other consideration, as was rightly mentioned by Ash, is the operability. Overhead cooling by fin fans will provide you with a rain detector, cooling improving as the weather gets worse. The same thing would happen to your column, along with changes in wind speed, ambient temperature and the like.
To be honest, I would have a wander round site, look at a few similar temperature/pressure columns and see what's been done there, and a chat with operations to see if it works. A few quick calculations on cost of energy vs heat loss to confirm that what was appropriate is still right now that energy prices have increased, then stick with something that has been shown to work.
