What is Life Cycle Cost (LCC) analysis used for in sustainable design?

• A. To compare only initial construction costs
• B. To compare total costs of ownership (initial, operation, maintenance, and end-of-life) to determine the most economical option over time
• C. To assess zoning compliance
• D. To evaluate aesthetic impact on property value

Answer: (B)

Life cycle cost analysis looks at the total cost of owning and operating a building over its entire life. It adds up the initial construction price, ongoing energy and operating expenses, maintenance and repair costs, major replacements, and end-of-life decommissioning or disposal. By evaluating these costs over a defined time period (often using a discount rate), designers can compare different design options to find which one is most economical in the long run. This approach helps prioritize investments in energy efficiency, durable materials, and low-maintenance systems that reduce overall costs and support sustainable goals. It isn’t about zoning compliance or aesthetics, which are outside this type of analysis; it’s about identifying the option that offers the best total cost over time.
