What must occur if a project includes a CFC phase-out plan?
A: The CFC-based refrigerants must be replaced with HCFCs
B: The annual leakage of CFC-based refrigerants must be reduced to 5% or less
C: The CFC-based refrigerants must be replaced with low ODP refrigerants
D: The project must implement green house gas emissions reporting

参考答案: B

本题解释:
The CFC-based refrigerants do not have to be replaced with HCFCs - they can be replaced with other refrigerants.

Be careful of the wording of questions that use absolute terms such as must, not, always, etc.

LEED does not require greenhouse gas emission reporting or tracking.

The project team can take 5 years from project completion to phase out CFC-based refrigerants, as long as the annual leakage rate of CFC-based refrigerants is reduced to 5% or less.

Projects that have a shown a simple-payback of CFC based refrigerant systems will take more than 10 years can be exempt from this requirement, but must still reduce the annual leakage rate to 5% or less.

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.
