D: Soft cost

参考答案: B

本题解释:
Life cycle costing (LCC) is the evaluation of the total cost of a building or product over its useful life, including initial, maintenance, repair and replacement costs as well as savings. LCC evaluates economic performance; By far the largest portion of the expenses in a construction budget, the hard costs are mostly comprised of the actual construction costs incurred to build the project. The hard-cost categories are the bricks and mortar of the project. Examples of hard costs include masonry, wood, steel, carpet, tile, mechanical systems, roofing; A soft construction cost is one that is not directly related to building, construction, etc. These include building permit fees, architect fees, legal, financing, engineering fees, commissioning, and other costs incurred before and after construction.
Life cycle assessment (LCA) is the investigation and valuation of the environmental impacts of a given product or service. LCA evaluates environmental performance. This view takes into account the whole life of a product or project (not assessing it from a single point in time).
