Attatched greenhouse book recommendation? And question.

Hello, everyone.
I'm looking at buying the house I've been renting for the past year
in Indianapolis (39N47). It's in the burbs, but the southside is
basicly unblocked, even during December. (The only obstruction is a small
deciduous tree which I am loathe to cut down.) The price is right.
It needs new windows, and of course, the insulation is insufficient
at the moment. I'd really like to add an attatched greenhouse for
both solar gain and to serve as a lounging area.

I'm not handy with tools (that's what friends are for), but I can probably
still pull off first-year calculus if need be. Can anyone recommend a book
that will educate me on my construction options, how to compute the thermal
gain, and other things that a total newbie who overlooks the obvious would
need to know?

On another note, this house already has some solar heating. On the roof
are two panels (one on either side of the peak) that collect heat, and
there are switches to turn on a pair of blowers.  The current owner can't
tell me much about them, and I haven't climbed up in the attic yet to
peer at them. The thing that disturbs me is this:

The air-intake and air-outtake vents are all on the ceiling. Shouldn't
one of them be on the floor? The primary living spaces of the house have
very high, vaulted ceilings, and I have the sneaking suspicion that a lot
of the heat is stratifying or pooling up there.

Any references, resources, and insights greatly appreciated.

Thanks!
WB

I like "The Homeowners Complete Handbook For Add-On-Solar Greenhouses
and Sunspaces"  Andrew Shapiro, 1985
This is out of print, but you can get it from Amazon.com used books
(at a great price).  This book has a lot of solar sizing info as well
as some good construction stuff.

I'd give the heat/return vents a try where they are, and see if you
can detect any bad effects (like short circuiting of the heated air to
the return or lots of temperature stratification).  A couple of dime
store thermometers would be all you need to get an idea how well the
arrangement works.

I got that book on Gary's advice, and it is a great book. Well worth the
price.
