<div dir="ltr"><div><div><div><div><div><div><div><div><div><div><div>Hi all,<br><br></div>I know this kind of question has already been asked, but I can't seem to find a complete answer, so here it is again, maybe someone can help :<br>
<br></div>I'm using a window type in a building simulation, and for this I choose a window from the library "/American/w4-lib", ID 2306. Thiw window type has 2 layers of glass separated by a layer of gas.<br>
<br></div>My question is regarding the Emissivity properties that can be read :<br><br></div>Emis F 0.840 0.060<br></div>Emis B 0.840 0.840<br><br></div>I just want to be sure of what that means : I guess "F" and "B" are for "front" and "back", but which of these sides is actually towards the interior of the building ?<br>
</div>Also, which window is on the interior side, and which one on the exterior side (1st or second column ?) ?<br><br></div><div>I think that for exterior walls, TRNSYS uses "back" to describe the "outer" face of the wall (outside). But I also read somewhere (..) that for instance "Rfsol" (so "front" reflectance) in the window description is also for the exterior facing side of the window.. In the end, I don't know if "front" is supposed to mean "interior facing side" or "exterior facing side".<br>
</div><div><br></div>Also, in the window description, there are dimensions (width, height). In the Window Type Manager, there are also dimensions taht you can enter ("For 1 glazing module", just below "slope of window"). Finally, in the different zones of my building where I actually use this type of window, there is an area which correspond to the area of the window I drew in sketchup.<br>
<br></div>==> which one of these area is actually used in TRNSYS computation?<br><br></div>Any help would be greatly appreciated ! I've been looking in WINDOW manual, as wel in the TRNSYS manuals, I can't find anything in there...<br>
<br></div><div>Thanks ,<br></div><div><br></div>Arnaud.<br></div>
