In passive solar design, its common for people to overestimate the importance of Thermal Mass TM. It can be easily argued that Airtightness and Insulation are much more important. The paper mentions that ACH50 is important with the insulation but ACH50 is actually more important than insulation in the home as a system.

Use as little as possible, locate it higher on the wall and protect it with as big an overhang as possible. Sunrooms are crappy performers for the most part. What's your main intent? Plants or living space?
