Dear Christoph, Thank you for your response! The problem is that, it seems to me, that I don’t have internal shading, so QSOLTR should equal QTSABS. Am I right? How should I set window type and external devices to get QSOLTR=QTSABS? Kind regards, From: hotline [mailto:hotline@Transsolar.com] Dear Karol, QSOLTR is the total shortwave solar radiation transmitted through external windows and internal shading. QTSABS also includes the secondary heat flux which includes the convection of internal shader. Hope that clarifies your energy balance a bit. Best, Christoph Von: TRNSYS-users <trnsys-users-bounces@lists.onebuilding.org> Im Auftrag von Karol Bandurski via TRNSYS-users Dear All, I am going to find whole solar gain which come to zone throug windows. There are two outputs that I consider: QTSABS and QSOLTR. It seems to me that bigger should be QSOLTR, because it is shortwave radiation transmitted through window (but not kept 100% in air node). The QTSABS is what exactly has been kept - has been absorbed by inside surfaces. But it is appear that QTSABS > QSOLTR… Could you write me what is right interpretation of those outputs?
