Which of the following methods can be used for minimizing refrigerant leakage in buildings to...

LEED v5 EAc7: Enhanced Refrigerant Management includes a specific pathway for limiting refrigerant leakage. Under the design requirements, applicable refrigerant systems must incorporate strategies that reduce leakage risk, including automatic leak-detection systems in fully enclosed spaces containing equipment above the specified refrigerant-charge threshold. The operational requirements also include maintaining and calibrating these leak-detection systems and tracking refrigerant leakage. CFCs are inappropriate because they have significant ozone-depletion impacts and conflict with LEED refrigerant-management objectives. Ammonia can have a very low global warming potential and may be appropriate for certain specialized refrigeration applications, but merely selecting ammonia is not itself a general refrigerant-leakage detection strategy. Therefore, implementing automatic refrigerant leak-detection devices is the method directly aligned with EAc7 ' s leakage-management provisions. U.S. Green Building Council
