General instructions 1. It is recommended to use EXCEL to facilitate computations. You will need to display the computations (in Excel or by hand, if you decide not to use the Excel functions). 2. If you make use of Excel, the file must be sent in original format. PDF documents or documents with cells with frozen results (No Paste Values) will not be accepted. Result cells should illustrate the functions used and reference cells, as applicable. The teachers' office area in the Antonio Lucchetti building has issues associated with the air conditioning system. Currently the existing system is centrifugal. The Department of Buildings and Land is evaluating two alternatives to address the situation. The first alternative is to replace the 50 tons centrifuge (chiller), the handle system and its isolation system. The upfront costs are as follows: Unit Cost Life Centrifuge 50 tons Handlers Installation work $33,000 $47,000 $1,400 $2,500 $22,000 15 years 30 years n/a n/a n/a *Reduces to 40% of original cost in case of equipment replacernent. Materials for initial installation ** Islation system ** The cost of replacement materials is also assumed 40% of the original cost.

The total hours a regular employee works at the Campus is 1,950 hours per year, at a rate of 7.5 hours per day. (You must calculate the cost associated withthe time staff spend on the maintenance tasks of these particular equipment.) The additional costs associated with the centrifuge operation are as follows The additional costs associated with the centrifuge operation are as follows Cost item Frequency Every 6 years Cost Cold water pipe insulation $22,000 replacement The costs associated with power consumption to the centrifuge system are as follows: The cost of daily electricity consumption of a 50-ton centrifuge is $150 per day. The cost of power consumption of the handler is $25 per day. The centrifuge system operates continuously. The second alternative is the installation of a system of individual units consisting of four capacitors and 41 consoles. The upfront costs are as follows: Cost item MDV 400 capacitor MDV 450 capacitor Unit cost Units Total cost Life $9,000 $9,700 $700 $900 6 years old 6 years old Consoles 12,000 BTU 6 years old 6 years old 31 Consoles 19,000 BTU 10 Materials" $35,000 n/a The second alternative is the installation of a system of individual units consisting of four capacitors and 41 consoles.

The residual value of the equipment corresponds to the cost of disposition of the unit c. Analyze a 30-year horizon d. Consider an interest rate of 6% 2. Perform a sensitivity analysis, keeping centrifugal system parameters constant, and changing the console system life from 5 years to a maximum of 10 years. 3. Consider that the equipment will be purchased by a manufacturing industry. a. Determine the internal rate of return at which both alternatives are equally attractive. B. Assume that the console system previously analyzed will be used to provide air conditioning in a manufacturing industry that generates a taxable incorne of $3,000,000 to $5,000,000 per year. It will be installed in a certain production area that generates an income of$450,000 gross annually. Operating costs are $125,000 per year. Depreciate the console system, in an operational state, using the Modified AcelerCapital Recovery Finger System and determine the cash flow aftertax.
