Which statement best defines cost-benefit analysis in green design?

• A. Focusing only on initial construction costs.
• B. Weighing the costs and benefits of sustainability strategies over time.
• C. Measuring the color and texture of materials.
• D. Estimating the fastest method to install the project.

Answer: (B)

Cost-benefit analysis in green design means weighing both costs and benefits across the project's life cycle, not just the upfront price. It looks at initial construction costs alongside future energy savings, ongoing maintenance, durability, health and environmental impacts, and even end-of-life considerations. By evaluating these factors over time, designers can compare options using metrics like lifecycle cost or net present value to determine which choice delivers the best overall value. That’s why the statement that weighs the costs and benefits of sustainability strategies over time is the best fit. Focusing only on initial costs ignores future savings, measuring color and texture isn’t about value, and the fastest installation method relates to schedule rather than long-term value.
