Which projects would not be eligible for LEED certification(choose 2)
A: A new project that uses hydrocarbons (HCs) as refrigerants
B: A new project that uses CFC refrigerants
C: A new project that uses no refrigerants
D: An existing project phasing out the use of CFC refrigerants no later than 5 years after the project is completed
E: An existing project reduces CFC by 95% prior to submitting the LEED application and will continue to use for another 10 years

参考答案: BE

本题解释:
Notes:

Reference: LEED 2009 for New Construction and Major Renovations Rating System
Hydrocarbons (HCs) are a group of refrigerants that are a type of natural refrigerant. Examples of hydrocarbons include propane, butane, ethane, isobutene, and isopentane.

New buildings cannot use CFC-based refrigerants. This is called Fundamental Refrigerant Management in LEED.

The use of no refrigerants is preferred when possible.

For existing buildings with CFC-based refrigerants, a phase out plan must be in place that eliminates all CFC-based refrigerants within 5 years of project completion. For such projects, the refrigerant leakage rate must be reduced to no more than 5% each year.

E: This would not be eligible unless the project had a phase-out plan in place at the time of the application and the CFC-based system was phased out within 5 years (not 10 years).
