Bridging and program performance

Andy,

more questions...

1. I see that DB doesn't account for bridging in the EnergyPlus simulations. Will this be remedied in the future?

2. DB interface is *very slow*, the slowest I've seen in any program. To make myself clear, the CPU dependant things like 3D and simulations are fine, it’s the GUI that is bafflingly slow: changing tabs, changing construction types, materials, opening dialog boxes, etc. Every change or click makes the computer blink for about ~1-2 seconds... making DB painful to use. Also the file i/o is very slow. Simulations happen in reasonable time, but then it takes DB a couple of minutes just to load the data in. I don't know if these are limitations of your framework, but will this improve in the future?

Troy,

1. We plan to account for thermal bridging across corners and edges in the near future.

2. I have come across this problem with the DesignBuilder interface on my development machine just recently and I know roughly what is causing it, but have not yet found a solution. The problem is due to a bug with a third party component used by DesignBuilder and I have contacted the developers to get a fix for this. Do you have another computer you can try?

Most DesignBuilder users do not encounter this problem (you are the first to mention it) - it only occurs under certain situations and I managed to stop it happening on my computer by restoring the Registry to a previous setting.

Has anyone else out there seen this problem?

I will let you know as soon as I have any more information on this.

Andy
