A retrofitted space heating system is being considered for a small office building. The system can be purchased and installed for $116,000, and it will save an estimated 320,000 kilowatt-hours (kWh) of electric power each year over a four-year period. A kilowatt-hour of electricity costs $0.07, and the company uses a MARR of 15% per year in its economic evaluations of refurbished systems. The market value of the system will be $6,000 at the end of four years, and additional annual operating and maintenance expenses are negligible.
