Which methods are commonly used to assess building life-cycle costs?

The assessment of building life-cycle costs is a comprehensive process that takes into account various financial aspects throughout the entire lifespan of a building. This includes not only the initial construction costs but also operating costs, maintenance expenses, and potential resale value.

By evaluating the initial costs, one can understand the upfront investment required for construction. The operating costs provide insight into the ongoing expenses associated with running the building, including utilities, insurance, and property taxes. Maintenance costs are crucial for assessing the long-term sustainability of the building, as they represent the necessary expenditures to keep the structure in good condition over time. Lastly, considering the resale value is essential for understanding the building's value at the end of its life cycle, which can significantly affect the overall financial assessment.

Incorporating all these factors ensures a holistic approach to understanding the financial implications of owning and operating a building, making option C the most comprehensive and correct answer for assessing building life-cycle costs.
