Fixing CheckWarmupConvergence: Loads Initialization

edit

I am working on Large office IDF with Ice storage. I am getting some warnings and severe errors that I wanted advice to fix:- error file:-

** Severe  ** CheckWarmupConvergence: Loads Initialization, Zone="BASEMENT" did not converge after 30 warmup days.
**   ~~~   ** See Warmup Convergence Information in .eio file for details.

I tried increasing the tolerance to 0.07 and 0.1 but still getting the errors. Can anyone help me help get to identify the problem and solution.
