Dear TRNSYS users, The documentation on Multi-zone Building suggests that the emissivity values of the glazing layers (Emis F and Emis B from the property data block of a glazing) are used by the
window model. However, when I try to manually change these values for a glazing, the U-value (u-WIN, output 50) of the glazing does not change.
But, I also observe that two glazing systems that have the entire property data block same, except ‘Emis F’ of the inside pane (e.g Window IDs 2201 and 2202), report different
u-WIN values. And, when these ‘Emis F’ values are kept same, u-Win values do not match. Can somebody explain how does Trnsys read emissivity values of the glazing? Is there a way to change the emissivity values of a glazing surface?
