We have not noticed this issue. Perhaps using "Clear to Default" and then selecting the glazing again helps. If it does not work, you can send the model for us to look at..

Alice,
As Andy mentioned earlier coefficients cannot be used for defining the gas mixture. E+ uses separate object (NOT the COEFFICIENTS) to define the gas mixture. DesignBuilder will introduce the ...

Alice,
I would recommend not to use the values you listed. You would be better off using just pure Argon. It looks like W5 does not store the coefficients correctly in gas table. It does calculate th ...

You are right, Florent. My apologies for not cross checking it. It looks like there is a glitch in reporting the coefficients for the mixtures in WINDOW5. I will clarify with LBNL and get back to you ...

Alice,

You can use WINDOW 5 program, a freely available software ( windows.lbl.gov), to calculate the gas mixtures. For 90% Argon and 10% air mixture the properties are as follows:

Name Arg 90% ...

Max,
The ASHRAE templates are planned for ver 2.0/post ver 2.0. That time you could use the templates for LEED certification purposes..

Carlos,
I agree current version of DB does not allow that option. This option would be included in near future. In the meantime you would need to export idf file and define the set point temperatur ...

Carlos,

The HVAC operation is used for defining your setpoint temperatures. The following article may help in understanding the setpoint temperature definition in DB.

Carlos,
You can define the schedule for heating/cooling under the HVAC tab. You would need to check heating/cooling on..

Mike,
It looks like the problem occurs when you export your idf file using older version, e.g. in your case 2.1... It works fine if you export using the recommended E+ version (ver 2.2) i.e. it does ...

Hi,
Yes, you can get data in /area units. Just check Normalise on under the display options when your simulations are complete.

Rahmi,
The hole for staircase is the same (6.632 m2)for the ceiling of Lt.Dasar/Zone1 and for the floor of Lt.2/Zone 1. The layout also show the staircase in Green both on the floor and ceiling. So ...

Dear Rahmi,
It may be due to large file size. You can save the models without results - Go to File/Save/Save without Output results..

Rahmi,
If the hole is created on the ceiling of the lower zone then it would automatically be created on the floor of the zone directly above. I am not sure how were you able to create another hole o ...

Hannes,
The difference probably is due the different heat transfer coefficients used in the calculations of U Factor. For example, EN673 uses exterior heat transfer coefficient - ho=23 W/m2K while A ...
