Hi,

I'm having the same problem with the latest beta release. When I simulate a whole year (just occupied periods), the interval "6-distribution" gives only one single temperature bin of 20°C. I'v ...

Hi,

No further investigation needed. I figured out that at surface level, the partial ground adjacency is clearly visible.

It just doesn't display what I expect at zone level, but I'm convinced ...

Hi,

I'm trying to simulate a building with an inclined ground slope. I followed the instructions given in the online help (topic = ground modelling). But when I take a look at zone level, a surface ...

Hi,

I'm using the latest DB-release (1.5.0.058) and I see very strange things happen: when trying to adapt an existing wall template, the details of the used walls don't appear. Instead there's som ...

Thanks for the quick reply,

Now it's clear why the shading was acting "strange".

But I think it would be a great feature if the shading control could be met by operative temperature. Maybe an i ...

Hi DB,

I'm having quite a strange problem, I've put window shading controlled by inside air temperature and solar gains almost remain the same (as a variant without shading). Still the inside air t ...

Andy,

I've just sent you the files by e-mail.

Hi Andy,

I have completed a simulation of an office building and get strange results for the fans energy consumption.
If I compare the DB results with manual calulation I get a 4-5 error factor.
...

Problem solved with release 1.4.0.056. Thanks, Filip

Problem solved with release 1.4.0.056.

Hi,

I'm using version 1.4.0.048. A model with an atrium space generates unexpected air changes.

Used parameters: Unitary single zone, mech vent by zone (1.3 ac/h in offices), ventilation schedu ...

Dear Arturo,

Due to confidenciality reasons, we don't post files on the forum. I'm sorry.

Let's hope DB finds a reason for those strange results!

Bye,

Hi there,

Simulating an atrium (but no roof glazing) created by a horizontal hole, we've encountered something strange. Taking a look at the simulation results on the ground floor, we have consider ...

Hey Laurent,

Ye I do see that graph.
But e.g. when I define natural instead of mechanical ventilation, I get that air change graph + in the 'Zone heat balance' "Ex nat vent" is shown.
When using ...

Hey,

"The zone heat balance" shows all fabric heat gains/losses, but suprisingly not all the ventilation heat losses; it only goes from "Glazing" to "External infiltration".
In 'display options' ...

Maximum heating power for a zone:
'Building model options' -> 'Data' tab and in the HVAC tab u can set 'Autosize' to 'Manual'.

Hopefully this helps.
