[EnergyPlus_Support] Calculated design cooling load for zone is zero.

Hi,all. Happy new year!
I made a model with DB, and then ran with E+, there are some mistakes like calculated design cooling load is zero. Then I checked sizing:zone and thermostat input. And I can't find erro.The temperature in those zones can't be controlled in summer. Did anybody met this kind of problem before? Could you make some suggestion for this warning? Thanks.
The erros are copied below:
** Warning ** Calculated design cooling load for zone=BLOCK1:ZONE1 is zero.
