Dear Franck, As far as I know, it is not possible to have temperature dependent properties in Type56 wall layers. With the feature that allows you to change the window ID number during the course of a simulation, you might be able to simulate changes in window properties as a function of time however. I believe also that some groups have worked on phase change material components of one kind or another (we did some work on photovoltaics with phase change materials and I also saw a PCM tank model recently). However, none of those models plug in to the building as far as I know. The best approach might be to write a variable property wall component that connects to a Type56 wall through a boundary temperature approach such as is used for modeling slabs on grade.
