Particularly noteworthy and useable is the material from the Vital Signs
curriculum materials project, located at
http://www.ced.berkeley.edu/cedr/vs/inf/rps.html
I highly recommend
"Thermal Mass in Passive Solar and Energy Conserving Buildings"
by Bruce Haglund and Kurt Rathmann from the University of Idaho
There is also some excellent information located at
http://www.aud.ucla.edu/energy-design-tools/
in particular, the Solar 5.4 software simulation program and the
examples and users manual that accompany it.
