试卷: LEED GA模拟题A[查看] 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. |
