Openstudio unwanted changes on idf file Hi Everyone, I was trying to use a openstudio measure to split windows into dif

Hi Archmage, Thanks for your answer. I am going to model a low-e double glazed window with a internal shading layer. I see the ASHWAT model can be applied for heat balance of CFS taking into account it's angular solar optical properties .

Is there any chance to incorporate angular optical properties of shading layer Roller shades and Venetian blinds in daylighting module?

I think E+ takes into account the angular optical properties of glazing layer in daylighting module but it does not consider angular optical properties for the shading layer. Thanks again.

Hi, I need to use window heat balance in Energy plus. In engineering reference there are : 1)different heat balance methods and algorithms given for window, shading, window with gaps,frames,etc. and 2)another heat balance calculation using equivalent fenestration method which uses equivalent layer method for all window and shading layers. Are both methods used at same time for heat balance calculation or the methods are chosen between one of the two depending on the input provided? If they are not used at same time, which model is more feasible based on the data about window and shading we have from window manufacturer and which is better in terms of accuracy ? I'd really appreciate it, if someone could answer my question.
