Your company is trying to reduce energy costs for one of its warehouses by improving its insulation. Two options are being considered and it is up to you to recommend either urethane foam or fiberglass insulation. Use a 12-year analysis period and an interest rate of 7 percent. The initial cost of the foam will be $37 000 and it will have to be painted every three years at a cost of $3 000. The energy savings is expected to be $6 500 per year. Alternatively, fiberglass batts can be installed for $14 000 with no maintenance costs. Fiberglass batts will likely save $2 600 per year in energy costs.
