[esp-r] Re: question about the ish module

[Jon Hand]

Sorry not to answer this sooner....

The shading and insolation module (ish) only deals with reducing the amount of
solar radiation arriving at a facade and being transmitted into a zone.

It does not have a concept of reflections from obstructions or other zone
surfaces.  I think this might be the first time there has been a request
for treating reflections.   If there were more requests for this and
someone to volunteered to champion the topic then there might be
progress.

Subject: [esp-r]  question about the ish module

Dear ESP-r users,
it is likely that my question has already been posted on the list.
Sorry for the repetition.

The question is the following. I see that the present version of the
Ish module does not take into account the radiation reflected by solar
obstructions into a zone (first reflection). Are you aware of any
tricks to get (at least partially) around this limitation? And are you
aware of any further improvements of Ish coming with the next versions
of ESP-r?

Thank you in advance
