Reply to comment by SomeConstructionGuy in Really want to build a house like this. Passive home stays at 70 degrees in Maine w/o furnace. by Twigglesnix

thank you for your help, I’m not trying to fully insulate the basement just trying to strike a balance between reducing heating costs, having a warmer floor during the coldest days and not spending a lot of money. I’m also thinking it would help avoid a sticking point when I sell since I can get this done for about $600 and insulation and maybe $30 for a painters suit, goggles and mask.

Depending where your mechanical equipment, what it is and how it’s insulated you may or may not gain much insulting the floor system. Depending what type of foundation you have (concrete, block, stone) it’s pretty darn easy to install 2” foam on exterior walls. Foam board on the foundation walls will certainly help all aspects.
