On a project with older existing HVAC&R system that uses CFCs what can the project team do to earn LEED certification?
A: Purchase carbon credits
B: Replace the CFCs with Halons
C: Replace the CFCs with natural refrigerants
D: Purchase Renewable Energy Certificates to offset the CFC use

参考答案: C

本题解释:
This is not a strategy to offset CFC use in a building;CFCs and Halons both cause damage to the ozone layer. Halons are primarily used for fire suppression systems;The project team can replace or retrofit the existing system with one that is CFC-free, or agree to have a phase out plan that is completed 5 years after project completion;Renewable Energy Certificates are used for Green Power and are not related to CFC use in a building.
