Insulate all exterior walls to at least R-11.

For example, for an addition you can use an unfaced R-11.5 over 8" Concrete Block (CMU) or preferred 12" thick CMU filled with concrete and wood or metal 2x4 studs on the inside with insulation. In addition to energy savings, you will create a room that has a more comfortable climate and you may consider finishing the floors so that it is more than just storage. Select a 'Formaldehyde-Free' insulation to save on air quality and health.

Consider using 12” vs. 8” Concrete block that is filled. If possible, excavate to have a ‘walk-out’ basement, and add exterior insulation (yellow panels) that also reduce the hydrostatic pressure that can cause leaky basements.
