not spending enough time out there. too much in here. and working on the house — the painters have been here for two days, prepping things, and I’ve put in five days of prep before that. mostly removing the damaged 3-inch poly foam insulation on the exterior of the foundation. several hundred square feet, I hope it does not impact the energy efficiency of the house overall, though it’s stupid to even think that — removing that much insulation will affect the thermal efficiency, period. it will. question is, how much. given the particular heating system for the house — the solar heat circulation system — simple but very effective. the house can survive the winter with interior temps dropping only to the 60’s F without additional heating unless there are three days of cloud, then the wood-burning stove can be kicked in. one cord for the entire winter tops. but the insulation, I’ll re-install that on the interior wall over what is already there, especially the north wall. hmmmm.
