Rubin, F L

The minimum annual cost method, the classical method of determining insulation thickness, is reexamined. This approach ignores profit. A variation includes a profit as a ''cost''. The installed cost is annualized and added to the cost of the lost energy. Payback period on installed cost is sometimes examined. All total cost methods are rejected, and incremental analysis is recommended. It examines each layer of insulation. The selected thickness has the final layer complying with a specified economic criterion. Selections are always for lesser thicknesses than those of the total cost methods, which dilute the energy saving of the initial layer with the savings of subsequent layers.
