Re: [TRNSYS-users] Solar absorptance and long wave emission coefficient

[Marion Hiller <Hiller@Transsolar.com>]

Fatmina,

0 and 1 aren't good choices for solar aporptance.
The manual of Type 56 (05-MultizoneBuilding.pdf) has a list of solar absorption values 
(5.2.4.2.2. DEFINITION OF A NEW WALL TYPE).
For longwave emissivity 0.9 is good value.

Betreff: [TRNSYS-users] Solar absorptance and long wave emission coefficient

Dear Sirs

I am modeling a building on TRNSYS, I defined a zone, what will be the value of solar absorptance and long wave emission coefficient for the floor ( note that the exterior layer of floor is made of tiling), and also for internal walls do they have a solar absorptance and long wave emission coefficient or should I put it 0

Regards

Fatima Harkouss
