Hi Annalaura,

Have you run a simulation being at site level, in order to verify if weather data is accurate enough?

Also, you can open the .epw file with Excel and use Text to columns command t ...

Hi Anna,

I’m not really an expert in this field, but as far as I understand, the compact method is the most precise and reliable.

In the other hand, each method handles data in a different way, ...

You must choose simple or compact HVAC in Model options.

if i choose this in the model options why can i choose the simple systeme or the compact ones, in the HVAC again?

No, you can’t. If you ...

Anna,

1. You have to choose compact HVAC only if you need to model mechanical ventilation in other zones (mixed ventilation). To learn about simple/compact HVAC options please read:

Anna,

If you are talking about visualizing normalized results after simulations, DB help says:

Normalise by floor area
Check this option if you wish data to be displayed 'per floor area' i.e. ...

Anna,

You have to select “calculated ventilation” in Model options. Then you need to active natural ventilation in HVAC tab. Also, it is necessary to have active openings (e.g. open windows) in Ope ...

Sorry for the delay to answer this topic.

If I understand your question, I think you can model this situation using calculated ventilation and compact HVAC model options.

The double fa ...

I’m afraid you can Smile

. It is possible to merge zones and blocks drawing holes and activating the model option Merge zones connected by holes (Model options > Advanced). Also you can use the model o ...

Hi Teresa,

It is difficult to know what is happening, but you can delete auto generated vents going to surface level (in the corresponding surface) and deselecting "Auto generate" check box.

Hi Teresa,

I’m afraid it is not currently possible (as far as remember) to obtain summarized loss/gains values. However, you can generate it easily. Just ask the software to show data in daily inte ...

Dear Teresa,

We have not updated downloadable DB version in Sol-arq because we have some troubles with our current site and are preparing a totally revamped one. However, software translation has b ...

Thomas,

You can do that by deactivating ‘Use slider controls’, in Program options > Interface > Interface style. Then you will be able to input the values manually.

Hi Antonio, welcome to DesignBuilder.

Even with adiabatic surfaces, DesignBuilder takes into account for heat flows due to thermal mass. It is the reason you see heat gains related with those surfa ...

Hi Francois,

If you have a complete hourly data set for a site you could try with EnergyPlus Translator, as Andy wrote in a similar previous topic:

“If you plan to do serious weather file transl ...
