G,
It is not possible to create laminated glass in DesignBuilder (or E+). You will need to use OPTICS program (you can download OPTICS at no cost from http://windows.lbl.gov/materials/optics5/default ... |

I haven't tried it in ver 1.5.0.076 but it works fine in latest relase version 1.6.9.002. You may want to update to the latest version..

No, not in the current version. .. You will need to add additional chiller in the idf file..

Lance,
If you know the properties of the glass, you can create your own glass. Go to panes library and either copy an existing glass or create new glass.
As you know several combinations of gla ... |

Donnie,
I did some investigation to find out the answer to your question, Is that a limitation from E+?
The answer is - Yes, the current ventilation setting in E+ is for cooling only. It is in th ... |

Yes, it would still be kBtu. You can just multiply it by 0.293 (1 kWh = 3.412 kBtu) to convert to kWh.

Teresa,
The probable cause of these errors is use of different version of E+. You may be creating idf file in older version of E+ and trying to run it in Ver 2.2 without transitioning. Additional fi ... |

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..

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 ... |
