Warning: Calculated design heating load for zone is zero.

edit

Hello my friends,

I have a problem with my simultion in EnergyPlus.

My building is locate in Mumbai, India. I'm using the system VRF for attend necessities of cooling in the design. My project need only cooling because mumbai is too hot whole year.

My intention is apply the parameters and the software calculate using autosize. In the thermost, it's necessary to specify a setpoint of heating but I don't need heating in my project.

When I simulate, there are a warnings about:

* Warning * Calculated design heating load for zone=4A61D4 is zero.

* ~~~ * Check Sizing:Zone and ZoneControl:Thermostat inputs.

Note: I use "Do Sizing Zone Calculation" on the SimulationControl.

How I can solve?

Thanks for attention.
