[esp-r] Emissivity

[Lewis Yook]

Dear All.

Let me ask you a simple but very urgent question. 

I refered to FAQ in Esru documations regarding this matter, but I couldn't find satisfacting answer.

1. Would any one of you tell me which part exaclty shows the emmisivity of the following double window?
=========================================

DCF7671_6omb :Clear float 76/71, 6mm open mid blnd
# def lyr, tmc lyr, vis trn, sol refl, sol absor, U val
1, 5, 0.76, 0.11, 0.28, 2.8
# direct trn @ 5 angles, total heat gain @ 5 angles
0.611, 0.583, 0.534, 0.384, 0.170, 0.711, 0.690, 0.645, 0.487, 0.250
# refr index, absorption @ 5 angles for each tmc layer
1.52, 0.157, 0.172, 0.185, 0.201, 0.202
1.00, 0.001, 0.002, 0.003, 0.004, 0.005
1.00, 0.172, 0.181, 0.178, 0.151, 0.097
1.00, 0.001, 0.002, 0.003, 0.004, 0.005
1.52, 0.117, 0.124, 0.127, 0.112, 0.077
===============================================



As far as I know, the emissivity should be described for each single glass.

2. That means, there should be two emissivity values on in one double window.
Is it wrong?

Your right answer will be highly appreciated.
