Box 62, Oak Ridge, TN 37831, This program allows individual users to estimate economic levels of insulation for their house, based on local climate data, local prices for energy and insulation, and the type and estimated efficiency of its heating and cooling system. 'while the current program is limited to calculating economic insulation levels for attic floors, exterior walls, floors over crawlspaces, and crawlspace and basement walls, it is anticipated that this will be expanded to include other components, such as windows water heaters, and duct work in unconditioned spaces.
