Problem with the Thermal Load Balance

[serismoon]

Hello everyone,

I am getting this error when doing the energy balance. I don’t want to use the ideal air system and don’t know how to add the annual load into my code.
Can someone please help me?

Thanks/ Serina

Honeybee_Energy Balance data matching error for model

Yes, @AbrahamYezioro has correctly identified the use of (non ideal air) detailed HVAC as the source of the error. But it’s not a bug and let me explain why you aren’t able to construct energy balances or match data to rooms with detailed HVAC results. When you run a simulation with detailed HVAC, the energy use happens on the basis of each piece of HVAC equipment rather than each room like ideal air systems. So I can have one boiler that serves 10 rooms and I can get the fuel energy use of th…

Here is the answer to your question

Thanks. ^^
So will the energy number be inaccurate if this error is shown?
In my case the bathrooms and the air spaces don’t need any heating nor cooling but they do need ventilation.

yes

The mentioned ventilation is another topic.

The ideal air is just for the architectural point of view for visual representation.
When you use HVAC system (not ideal), for having data, you need to read the sql then for each sector, use LB Mass Arithmetic Operation. This will give you the required loads.
