Dear all<br>
<br>
I'm looking to replicate some of the functionality of IES Radiance in
the full version of Radiance. This is so we will not be as restricted
by licensing ;)<br>
<br>
The feature I'm interested in is the illuminance calc on the working
plane of a space. This is frequently used to feed in to such things as
BREEAM or LEED credits.<br>
<br>
OK<br>
In IES Radiance, working on a multi roomed model, I would:<br>
<ol>
<li>Set up some basics, i.e. CIE overcast, materials, image quality</li>
<li>Select analysis type "illuminance - working plane" (usually 0.85
metres above floor level)<br>
</li>
<li>Select a space</li>
<li>Simulate!</li>
<li>Repeat 3 until all the spaces I'm interested in are simulated.<br>
</li>
</ol>
In terms of post processing I would <br>
<ul>
<li>convert each pic to daylight factors <br>
</li>
<li>Query the PIC by tracing an "Area of Interest". This is used to
work out DF min, max, ave, uniformity, etc. With this I can exclude
overlapping spaces and other features such as notional corridors from
the working plane calcs.</li>
</ul>
If I were to export a 3rd party CAD model (via, say su2rad) consisting
of N number of rooms, are there alternatives to the simple IES
approach? <br>
For example, a cad model would not possess the massing data of IES. <br>
<ul>
<li>Perhaps a surrogate for step 3 would be to define the view
explicitly in a file? <br>
</li>
<li>How do I set step 2 up? <br>
</li>
<li>I suspect it may all be controlled in view?</li>
</ul>
<ul>
<li>Post processing: Is there a tool with similar "area of interest"
functionality for querying PIC files?<br>
</li>
</ul>
I've had a good search through "Rendering with Radiance" but it doesn't
appear to cover this.<br>
<br>
Many thanks<br>
<br>
