Average sun path

In the Ladybug “sub light hours analysis”, how can I represent an average sun path “as a single line”?

I am calculating the amount of direct sunlight to building for a year. So, I need only the single path that indicates the average sunlight for a year.

Please help! Thank you in advance.

Hi limpideyessalmon,

are you sure that “amount of direct sunlight to building for a year” is the same as a single day with average sun position(multiplied with 365)?

What does “average” sun path mean? Average over summer and winter? Try that in Alaska!

Ladybug aside, here is a simple model for sun path. On the ‘Winter|Summer’ slider, zero is winter, 0.5 are the equinoxes and one is summer:

P.S. Sorry, I messed up instead of ‘±tilt angle’, I used ‘±tilt/2’. Fixed in version ‘b’ below:

sun_path_2019Nov9b.gh (10.1 KB)

I realize this is overly simplistic.

Yes, I am.

“Sun position” can be indicated as a single line over the year, such as the line from Spring, summer, fall, and winter. So, the average energy which a building gets over the year can be calculated.

For example,

  1. Every 6 am for a year, the sun position is differentiated. But in the curvy line, the average sun position can be indicated as a point.
  2. From the point, the sunlight which a building gets can be calculated.
    -> This will be the average.
  3. Every single hours for a year, the sun position can be represented as point.
  4. So connected these means the average sun light that a building gets.

That’s what I thought.

Any comments are welcome!

Thanks in advance.

I will check it out. Thank you a lot, Joseph!

Please note the correction I just made in version ‘b’, above.
