[TRNSYS-users] Buildings response to sine of solar radiation

[Maarten Sourbron]

Dear all,

Don't bother about this question anymore, I had left the solarshading on ...
So many parameters to take into account :)

Thanks,
Maarten

Is this zone experiencing any shading from another part of the building? Once the sun moves to a different angle and is no longer blocked, then the radiation would increase.

If I make change the solar radiation into a sine wave falling on a south zone of a building, I get strange peaks in de solar radiation transmitted + absorbed (QTSPAS) for that zone.  Apparently it is function of the minimum of the sine : maximal effect for Qsol_min = 0 and gradually dissappearing if I shift the sine higher (Qsol_min > 0).  See attached pictures.
Does anyone has an idea where this comes from?

Thank you,

Maarten Sourbron
