What is the main purpose of whole-life cost analysis?

• A. To compare options based on total cost over the building's life cycle, including operation and maintenance.
• B. To estimate only construction time.
• C. To maximize annual tax incentives.
• D. To optimize aesthetics.

Answer: (A)

Whole-life cost analysis focuses on value over the entire life of a building by including all costs from construction through operation, maintenance, replacements, and end-of-life disposal, usually discounted to present value. The main purpose is to compare different design or procurement options based on their total cost over the life cycle, so decisions account for long-term economic performance rather than just the upfront price. This helps balance initial investment with future running costs, energy use, and maintenance needs. Other options—such as estimating construction time, seeking tax incentives, or optimizing aesthetics—address different aspects (schedule, fiscal incentives, or appearance) that aren’t the core aim of lifecycle costing.
