Hi Valentin..

Thanks for your suggestion.
I have tried to do it, but I could only move a building block, whereas this building block has 9 component blocks. Do you think I have to move them one by ...

Dear Sir,

How to move a building block and some component blocks in a same time? So far I know that I have to move them one by one.. and it takes time, because I have 12 blocks! Is there possibili ...

Dear Sir,

Thanks for your suggestion.
I have calculated the heat balance, and the 'roofs' resulted by DesignBuilder apparently is only the conduction in the roof material.
I have to add convectio ...

This is the graph based on case 600 ASHRAE, with the roof material of steel, 0.0135 m thicknes.

Dear Sir,

In fact, my problem is that I found the 'roof heat gain' is very small (less than 10%)compare to the solar radiation.
Even I use the simple building of Case 600 ASHRAE, and using steel ...

Dear Sir,

I am now simulating a simple building in a tropical climate of which its solar angle is always high. I want to prove that applying roof insulation will reduce cooling energy demand.
Howe ...

Dear Sir,

I have just tried to simulate this building using DesignBuilder version v.1.4.0.056, just have a look what happens if I put insulation on the roof. The result shows that the zone sensibl ...

OK Andy,

I attached the model.

Thanks,

Andy,

Thanks for the suggestion.
I have tried to change the EP version for the new DB, and it gave the same result which means that when I do simulation using DB V.5.0.74, and using EP version 2.1 ...

Dear Sir,

I have just installed the newest version of DB, v.1.5.0.076, and simulated three different building models, then compare the results with previous version, v.1.4.0.056.
1. Case 600 ASHR ...

Hi Laurent,

Thanks for the explanation.
Concerning my last question, how to set the cooling machine so it works from 21.00 to 05.00? Do I have to set the Cooling Setback to (for example) 40°C? (to ...

Dear Sir,

I am simulating a building which is conditioned (cooling only) using daily schedule of 'ON' from 21.00 to 05.00.
I set (in the activity tab) the cooling set point temperature of 26°C a ...

Hi Carlos,

For your question concerning zone volume, maybe you can try to check the zone volume using Energy Plus.
Hopefully it helps.

Good luck,
Rahmi

Dear Sir,

I am now simulating a two storeys building, and I have a staircase connects between the storey. I draw a hole on the ceiling and assume this as the staircase. In my simulation, how do I k ...

Hi Arturo,

Thanks for the idea. Yesterday I also thought that it could be done like that. But, still I get stuck with the initial point.
1. Which comfort conditioning temperature should I use for ...
