Is it possible to use DesignBuilder / Radiance to determine the hours per year that a point 1.5m in front of the glazing, 0.72m above floor level will receive shading or sun penetration? And present t ...

Great, thanks for your help, Andy.

Hello,

I am trying to export the attached model to a .dxf file. I'm not getting any errors or crashes but the export never completes and I eventually have to force Design Builder to close as it wo ...

Hello,

I think I have come across a bug in the reports that DB generates. It only seems to affect zones sepparated by virtual partitions.

I've attached a xls file showing the problem. Take a lo ...

Thanks for the swift response Andy.

I had considered thermal storage, but over a week simulation run the net change still seemed high. Running longer simulations (month or more) gives a net change ...

Hello,

I'm curious about the results I'm getting when running this simulation. The heat losses through internal partitions seem very high, considering that all the zones are heated to the same temp ...

Thanks Andy, at least I know I am on the right track. It looks like I will have to be getting into the IDF files for the time being.

Any clues as to when v2.2 is expected to be released?

Hi,

I am trying to model the HVAC system for a new building. The building has two wings, connected by a narrow corridor.
The north wing is served by a constant-volume system. The south wing is ope ...

Hello,

I just posted to try and get help with a problem I am having, but was unable to attach the DSB file. The follwoing error message came up instead:

"Sorry, but the maximum filesize for all ...

Hi all,

I'm curious to find out a few more details regarding whta goes on behind the scenes with respect to 'Compact HVAC' systems. In particular, how is fan energy calculated? Does DesignBuilder e ...

It's easy enough if you export the results to a spreadsheet package such as Excel, and then sort the data in ascending/descending order. Or you could see it graphically from within DesignBuilder if yo ...

Thanks Andy, I installed the new version and that solved the problem.

Cheers,

I've got a problem with cutting a block along a plane. Attempting to cut the model as attached, along the plane defined by the construction lines causes DesignBuilder to crash without completing the o ...

Thanks, running DesignBuilder with the .exe file does produce the same output as running EnergyPlus directly. That's half the problem solved!

Now, do you know why the .exe and .dll produce differen ...

I'm having a little problem running simulations in DesignBuilder and in EnergyPlus.

What I am trying to dp is use DesignBuilder to generate IDF files of several options for building design, shading ...
