The cooling loads did not converge to within 0.04 (4 % of load). The cooling loads did converge with a maximum load difference of 0.06. It seems reasonable to me that the loads did converge to a small value, especially since the temperatures converged to 0.06 C.
You could either increase the number of warnup days to see if this will help the simulation converge or change the loads convergence tolerance to 0.065 to get rid of these warnings.

Hello dear forum,
I'm about to submit the EAp2 form for LEED Certification, but I still have trouble with simulating the Baseline model. I got the following errors, not only for the FLOOR12:OFICINA2 zone, but also for many zones in my model.
Please advice how can I fix it. Do I have to change the warmup days?
** Severe ** CheckWarmupConvergence: Loads Initialization, Zone="FLOOR12:OFICINA2" did not converge after 25 warmup days.
