Storage values - why so high?

[dsat]

Hi, I’m wondering if this results are (or can be) fair for building located in tropical climate?
Storage values are quite high for summer periods …

There is an annotation at storage - in energy balance:

@dsat would be better if you could share your script to review

Thanks, will send soon

Here is a simplified script. I will be grateful for any feedback.

@dsat,
You are using a detailed HVAC system in the file that you uploaded:

So the cooling/heating in your energy balance are not the energy that is added/removed from the zone. Instead, it’s electricity and fuel used by the HVAC system. Long tory short - if you are trying to construct an energy balance, you should always use an ideal air system. Not a detailed HVAC.

Thank you, Chris, I have already figured this out. Another issue is that the model and cooling energy results seem fair for only one glazing surface. If I add even a minor glazing surface on the other wall the cooling energy consumption increase two-fold, which is confusing. Any guides on how to fix the model?

Problem with energy consumption results due to implementing windows on more than one wall

Hi, I am simulating the energy consumption in the small residential dwellings in a tropical climate. The model and results look fair when I have a glazing surface only on one wall of the house. However, when I add even a minor glazing surface in the different wall the cooling energy consumption increase nearly two-fold. Any ideas on how to overcome this issue? In the attachment you can find the model, I am using the visualarq plugin which helps with the parametrical design of the house, howev…

Ok, I found the problem, which seems to be a natural ventilation forced by windows openings. I need to improve the logic of the windows openings
