At NYIT in 1993 a 100ton electric A/C system (electric driven compressor) with a 100ton natural gas absorption system. Electric then was $.12/kwh and the natural gas unit was expected to half the energy cost. Other date is listed below. Make a financial analysis and decide if a replacement is worth it. Lifespan of electric system=10 years and salvage S=0; Lifespan of the absorption system is 20 years and S=0(even after 10years) Energy savings = 50% of electric; Maintenance Cost/yr,Electric $2000/yr, gas $6000/yr: Initial cost of electric=0 (sunk cost), gas $60,000 and the installation is additional. $20,000. Gov’t funding is 30% of the initial cost. The interest rate is 6% and the air-conditioning system operates on average 1000hrs/yr. The may assume any other unknown factors. On a quantitative basis is the switch justified. Work the problem out either on a present value basis for 10 years or annuitized cost per year for the same time period.
