Hi!

Please can someone explain to me what is the pump usage,%, under the part load performance?

Thanks,

Hi,

I think these are for the rooms below ground, i.e. at the basement levels. They are in contact with the ground but are not exposed.

Hello,

Thanks for the replies.

I've tried the "Rebuild", nothing happened. Unmatched adjacencies are still there. I will upgrade to 6.4.0.7, and will advise you guys what happens. Thanks.

Hi!

Why do I get unmatched adjacencies when I put holes between the rooms? The store is divided into several room types (zones) but they are not separated by a wall (thus the holes). The adjacency issues only comes up when I add in 100% holes into the partition walls. But when I leave at least 10 ...

Hi Phil,

Alright then. Thanks very much.

Hi Phil,

Thanks for the reply. What I mean is, in the Create target construction tab, you can input the u-value that you want, say, 0.504 W/(m²-K), but how about the corresponding cM value? How do you determine this, or can you just accept the default value for it?

Thanks,

Xye

Hi!

I'd like to ask about the Project constructions > Tools tab.

How do you specify/determine a value for the Target cM value?

Thanks,

Hi Phil,

Thanks for the response. I've figured out the solution to the problem. I just have to change the building fabric u-values, as the instability occurs when there's too much heat gain in the room.

Hello!

I'd like to ask how to do a profile using PIR (Passive Infrared) Sensors (motion detection) to control the artificial lighting?

Many thanks,

Hi Phil,

Thanks for the response. I wonder if you have encountered this error message:

"Error: Instability in room B1. Possible remedies: reduce time step; set control radiant fraction to 0; check gain and ventilation levels; reduce Macroflo opening areas."

I did all the suggested remedies but I ...
