BASE FILE

Add a camera (positioned at top of marker), set its angle to 90 degrees horizontal and 60 degrees vertical.
Check lighting conditions (Jan 1st 2pm)
As seen from the Radiance illuminance results, the space is quite well daylit.

Add a spotlight, set to night time (7pm)

It is easier to prepare complex geometries in dxf (using a proper CAD tool). Try this lamp geometry. Insert a lamp using the guide line, and set the lamp to HighBayNarrowBeam with 600cd and 450lm.



Running a Radiance Luminance render this time, we get the following *.pic images.





Qn: What is the luminance ratio between the sculpture and the background?

Link to eco file. Note Radiance results not coupled yet.

Check new lighting conditions (Jan 1st 7pm)
Conduct a seperate Radiance illuminance render for the analysis grid and import the results.



Qn: Comment on the illuminance for the various functional activities, what would your strategy for improving the space be?

Glare (Jan 1st 7pm)
Radiance comes with a few tools to calculate glare from luminance images. First, we'd like to generate a camera view representative of the entire visual field. Add a 180 degree hemispherical camera 500mm away from the desk, 1200mm from FFL.



Proceed to generate a Radiance Luminance image from this camera.

Ecotect file with 180 degree camera here. No embedded results.
Using command line, use findglare to calculate glare sources (into *.glr file) from the luminance image.




Then use glarendx to calculate UGR or VCP (8.5 and 98% respectively in this case) from the *.glr file.



What happens to the UGR if the intensity of the lamp is doubled?
