Also check out a book called The new Cottage Home by Tim Tolpin, has some very nice floor plans that could lend themselves nicely to cob construction.</DIV></DIV>

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