Question


In a company’s renovation of a small office building, two feasible alternatives for upgrading the heating, ventilation, and air conditioning (HVAC) system have been identified. Either Alternative A or Alternative B must be implemented. The costs are as follows:

Alternative A:
Rebuild (overhaul) the existing HVAC
•Equipment,labor,and material store build.............$18,000
•Annual cost of electricity..................................... $32,000
•Annual maintenance expenses .............................$2400

Alternative B:
Install a new HVAC system that utilizes existing ductwork
• Equipment, labor, and materials to install ............ $ 60,000
•Annual cost of electricity........................................ $ 9000
•Annual maintenance expenses ...............................$16,000
.Replacement of a major component at EOY (4).......$9400

At the end of eight years, the estimated market value for Alternative A is $2,000 and for Alternative B it is $8,000. Assume that both alternatives will provide comparable service (comfort) over an eight-year period, and assume that the major component replaced in Alternative B will have no market value at EOY eight.

(1) Draw net cash flow for each alternative.

(2) Use a cash-flow table and end-of-year convention to tabulate the net cash flows for both alternatives.

(3) Determine the annual net cash-flow difference between the alternatives (B A).

Explanation / Answer

Answer:

Assumption : Since no market rate of return is mentioned in the question, let 5% be the market rate of return.

(1) & (2)


(3) Annual net cash flow difference between alternative (B-A) = $ (223768 - 238864) = $ -15096

Alternative A Alternative B Particulars Amount PV factor @ 5% Net cash flows Amount PV Factor @5% Net cash flows Initial Cash flows 18000 1.00 18000 60000 1.00 60000 annual cost of electricity 32000 6.46 206720 9000 6.46 58140 Annual maintenance cost 2400 6.46 15504 16000 6.46 103360 Major replacement cost at EOY 4 0 0.82 0 9400 0.82 7708 Estimated market value at EOY -2000 0.68 -1360 -8000 0.68 -5440 Net present value 238864 223768
