Lifecycle Cost Analysis: Which statement best describes LCCA?

• A. Life-Cycle Cost Analysis (LCCA): The evaluation of the cost of, for instance, boiler systems in a building from installation to replacement, including the cost to install, fuel to run, maintenance, salvage value after the useful life, and how long one system is expected to last, considering inflation.
• B. Life-Cycle Cost Analysis and Life-Cycle Assessment measure the same thing.
• C. Life-Cycle Cost Analysis focuses on environmental impacts across the lifecycle.
• D. Life-Cycle Cost Analysis is used to compare only initial installation costs.

Answer: (A)

Lifecycle Cost Analysis looks at the total cost of owning and operating a system over its entire life. It includes not just the installation price, but also the ongoing costs to run (like fuel), regular maintenance, possible replacements, and the salvage value at the end of its useful life, all evaluated over the chosen time horizon and often adjusted for inflation or the time value of money. The statement that best describes this is the one that lists installation, fuel, maintenance, how long the system lasts, salvage value, and inflation, because it covers all the components that contribute to cost across the lifecycle. The other options mix in environmental assessment or limit the scope to upfront costs, which does not reflect the full lifecycle perspective. In practice, LCCA helps pick the option with the lowest total lifecycle cost, not just the lowest upfront price.
