Direct sun exposure takeout

Post by romark » Tue Dec 22, 2015 4:37 pm

Hello everyone,

Imagine a building between others.
A new construction is projected on a site nearby and the amount of sun bathing of the existing buildings is changed (or vice-versa).
Is there a way to calculate the surface in direct sunlight for a given building elevation at a given time of the day?
Is there a way to calculate the light (energy) / surface in direct sunlight for a given building elevation:
- Over a given time lapse on a specific day?
- Over a given time lapse over a longer period (month, year)?

SketchUp and LightUp have all the information inside (I assume): how to get it out?

Does this ring a bell to anyone?

If not, can at least some extension draw lines on a plane in SU where the shadow hits (intersection between light and shadow materialized on the face)?
I would take out surfaces manually to Excel from there…

Thanks,
romark

Have you tried using the Lux Contours mode and choosing:

Daily Insolation
Daily Sunlight
Annual Insolation
Annual Sunlight

These show the results and the lightmeter will give spot reading for you too.

If you want a comprehensive set of functionality like this, I'd suggest looking at our sister product
LightUp Analytics (lightup-analytics.com)

Thank You Adam & Happy New Year!

The Lux Contours / Annual Insolation did the graphic job nicely (after orienting and repainting solid surfaces white).
I've attached the resulting images.
I'll have to take a look into LightUp Analytics (lightup-analytics.com) for quantities I suppose...

Quick Tip: Uncheck "Show Textures" to just see Lux Contours - no need to paint everything white!

Thanks: I've tried, didn't work for me.
The "no textures" still leaves the color - orange tiles on the roofs in my case - which was interfering with the orange shades of the insolation graph.
The other options (monochrome in SU, etc.) didn't work well either... so I had to paint it all in white.

Sorry Adam: you were right, I was wrong!
The Quick Tip indicated was for LightUp, while I was trying the "no textures" mode in SketchUp.
It works fine in LightUp, no need to paint everything white!
And, as opposed to other software, LU output is not influenced by hidden elements: great!
Also, I didn't notice the "incremental" vs. "final" options in LU were available in insolation mode: final output is so much smother.

Forums are for all of us to progress - I hope this is useful for many...
Here are too new images for the same project (opposite views).

Thanks again,
