"A 3.45 megawatt cooling, heating, and power (CHP) system was placed into operation for Southeast Regional Hospital with 360 beds. The CHP system was part of a new 20,000 sq. ft. central utility plant that provided the 800,000 sq. ft. health-care facility with cooling, heating, and power. By centralizing all of the utilities in one location, the hospital accrued significant energy savings, as well as improved maintenance efficiency. The financial facts related to the project are summarized as follows:

Installed cost: $3.6 million

Annual energy cost savings: $738,000

Annual O&M costs: $302,000

Project service life: 16 years

Salvage value: $300,000

At an interest rate of 5%, what is the net savings per dollar invested (rounded to the nearest hundreth)?"

"A local city that operates automobile parking facilities is evaluating a proposal that will erect and operate a structure for parking in the city's downtown area. Three designs for a facility to built on available sites have been identified and the costs and benefits are given below in thousands of dollars.

Design 1

- Cost of site = $286

- Cost of building = $1700

- Annual fee collection = $598

- Annual maintenance cost = $359

Design 2

- Cost of site = $263

- Cost of building = $2300

- Annual fee collection = $618

- Annual maintenance cost = $284

Design 3

- Cost of site = $260

- Cost of building = $500

- Annual fee collection = $729

- Annual maintenance cost = $357

The cost of building and cost of site are one-time costs to be paid immediately. The city's interest rate is 5.2%, and the life of the project is 37 years. If the three designs are mutually exclusive, which design is the best alternative? You can use incremental benefit-cost ratios or present worth calculations. Enter 1, 2, or 3 as your answer."

"A country is considering five different strategies to protect its border against illegal drug smuggling. The following depicts the cost of each strategy and the effectiveness, measured in tons of drugs apprehended. Use incremental cost-effectivenss ratios to select the strategies that are NOT dominated (see example 16.6). You may select more than one strategy.

Strategy A: Cost = $220 million; Effectiveness = 586 tons

Strategy B: Cost = $160 million; Effectiveness = 541 tons

Strategy C: Cost = $256 million; Effectiveness = 670 tons

Strategy D: Cost = $229 million; Effectiveness = 544 tons

Strategy E: Cost = $136 million; Effectiveness = 757 tons"
