Cob: second structure spacing

[Darel Henman]

We were all right.

Using Dec. 21 for an overhang, will give you the full sunlight on the
sun's lowest altitude reached on solar noon, when you want it.   It will
also give you sunlight on other days say from Sept. to March while the
sun is still below or equal to the Dec. 21st solar noon altitude, while
the higher noon altitude is cut off.   You'd still get incoming solar
energy until the sun reaches that altitude used.  For example you would
get full winter on Dec 21st if you used this date, but a little less
sunlight each day before or after this date around solar noon.  So if
you want the extra solar energy of high noon suns earlier than Dec. 21st
then that solar noon altitude should be considered.   Since the sun is
rises low, slowly and continualy rises then reaches it's apex, then
slowly curves down (actually as you know its the earth that's spinning
here, but).  You might want to balance to keep out all summer direct
solar energy to keep a place from heating up.

Anyway this is a fun little problem to solve.   Decide when to keep out
the hot summer rays and when you want to get the warming winter sun
rays.
