What is unconditioned space maximum temperature ?

normall it has no specific standard. If it is between a conditioned space and exposed area then we can take it the average. If it is between two conditioned spaces then we can take 5 Degc plus. If it has a heat source then it depends on heat source. If it is just a storage than we can use average between the temperatures.

it is depends up on the maximum peak load of summer seasons it may vary from country wise
