[esp-r] Sky view factor & External insolation

[Sean C Lu]

Hi

I am thinking to use Esp-r to simulate the solar performace of shading
device ( for exampe, the shading device integrated with solar collector) .
one of the task is to calculate the  solar radiation received by the surface
of the external shading device.

there are two questions for the calculation of incident radiation :

1 can esp-r calculate the insolation for the external face of surface? (The
shading and insolation program (ish) can only calculate the distribution of
insolation within ZONE ?)


2 as we know, the Incident Radiation of Surface = Unshaded Fraction
* Incident Beam Radiation + Sky View Facter * Incident Diffuse Radiation +
Ground Diffuse Radiation
to calculate the component of diffuse radiation ( the 2rd term)  , the
fraction of Sky View Facter must be known, is there any application can
calculate the SVF? ( it seems that the application of ESPmrt  only calculate
the viewfactors between surfaces within A ZONE)


many thanks for your help.
