What defines the total of the energy necessary for an entire product”s lifecycle?
A: Embodied energy
B: Simple payback
C: Life cycle analysis
D: Life cycle assessment

参考答案: A

本题解释:
Embodied energy is the energy used during the entire life cycle of a product,
including its manufacture, transportation, and disposal, as well as the inherent
energy captured within the product itself. (USGBC)

Simple payback takes the cost of an item or strategy and divides that number
by the yearly savings that product or strategy creates. If replacing a
CFC-based system costs $150,000 but saves a property manager $50,000 a
year, the project will have a simple payback period of 3 years.

Life-cycle-analysis (LCA, also known as life cycle assessment, ecobalance,
and cradle-to-grave analysis) is the investigation and valuation of the
environmental impacts of a given product or service caused or necessitated
by its existence.

Life cycle assessment evaluates a products “environmental impact”.
