Light Analysis in SketchUp
IN-DEPTH
Especially if you are creating interior spaces in SketchUp, one common task in lighting
design is figuring out light intensities (e.g., over workspaces). As part of this task, light
amounts must be quantifiable (typically, in a unit called lux). Depending on the rendering
software you are using, this may be a possible output that it can deliver. If the software is
calculating light paths realistically anyway, why not use that data for analysis?
Figure 5.63 shows such an analysis. As you can see, light intensity has been colored in
a false-color pattern, where the brightest areas are red and the darkest areas are blue.
To make such an analysis possible, you must use correct lighting data. Instead of using
just light intensity factors for luminaires, make sure you enter correct wattages. Some
rendering software also accepts watts per square area as a unit. This is especially useful
for area lights such as light boxes and neon fixtures.
