U Value of Glazing being changed Automatically

[pratikz]

Hello IES,

I am using IES since 9 months and having been using IES VE 2013 and 2014. In 2014 version with feature pack update, I am facing issues with Net U-Value (including frame) being updated automatically in Project Construction. Its like, I achieve specific U-Value using double glazing window and changing Resistance. Then I press OK and and press save to project construction menu and press OK to exit. But when I reopen the Construction of Glazed, the U-Value is changed to some figure which different to what I had input.

Please help.

Currently, the U-value is getting reset to CIBSE methodology values and thus appears inconsistent when using ASHRAE or EN-ISO instead. IES is aware of the issue and will have it resolved in a future release of the software so that CIBSE is not always the default view.
