AB - Support for complex fenestration in lighting simulation has been in the
focus of recent Radiance development. The concept of contribution
coefficients has driven not only climate based simulation, but also
allowed to efficiently study variants for fenestration designs and to
derive the area-averaged BSDF from geometrical fenestration models.
With the new refined algorithms implemented in Radiance, we show from a
users point of view what solutions are currently offered to model
components of fenestration systems which are available on the market. As
a test case, an interior space is modeled in detail. Problems arising
from combining the new approaches to model complex fenestration when
aiming at daylight metrics currently in use and the transfer of measured
data are discussed. Fields for future development are proposed.
