A retrofitted space-heating system is being considered for a small office building. The system can be purchased and installed for $98,000, and it will save an estimated 200,000 kilowatt-hours (kWh ) of electric power each year over a six-year period. A kilowatt-hour of electricity costs $0.13, and the company uses a MARR of 12% per year in its economic evaluations of refurbished systems. The market value of the system will be $19,600 at the end of six years, and additional operating and maintenance expenses are $10,800 per year. Use the benefit-cost method to make a recommendation. Click the icon to view the interest and annuity table for discrete compounding when the MARR is 12% per year. The conventional BC ratio of the system is (Round to two decimal places.) This BC ratio indicates that the project is A retrofitted space-heating system is being considered for a small office building.
