Here's a quote from one of the documents that John references above,
"Thermal Mass in Passive Solar and Energy-Conserving Buildings" by Bruce
Haglund and Kurth Rathmann:

(p7)"A masonry wall with exterior insulation is a thermally elegant
construction. It is effective during both heating and cooling
seasons...A masonry wall that is insulated on the interior is thermally
isolated from internal gains and solar gains that enter the building
through glazing. Its mass is virtually useless in management of indoor
temperatures."
