Dear Scumbria: I live in Wisconsin. We just had 6" of snow. I worked 3 weeks out in the Bay area on a warehousing project in February of last year. By my standards, it was typical September weather for my hometown, highs in the 60's and 70's with lows in the 30's and 40's. 2" of foam insulation can have a R value of 20. If the walls are nothing more than 2x4s with two pieces of wallboard (plaster) on them and as cheaply constructed as that, foam filling it should be a snap. Do not forget that you can replace the windows with triple pane low-e glass. You could have the roof foam filled. The R value of an empty 2x4, really 1.5"x3", built wall is about 7-10. The reason foam filling works is it reduces convection currents inside the walls and any air infiltration (drafts). Doing the above, can cut your heating and cooling bills by as much as four times (1/4). The building in silicon valley are built to such low standards that most of them would be condemned in anywhere in Wisconsin. By the way, a basement acts like a high thermal mass to average out the peaks and valleys in temperature (here the ground temperature (below the permafrost level) is about 43 to 46 degree Fahrenheit).
