Entry Type ID Date Applicable Rating System Primary Credit Inquiry (LIs) Ruling (LIs) Related Addenda/LIs Related Resources Campus Applicable Internationally Applicable Country Applicability Reference Guide (Addenda) Page (Addenda) Location (Addenda) Description of Change (Addenda) "LEED Interpretation" "10039" "2011-05-09" "New Construction, Existing Buildings, Core and Shell, Schools - New Construction" "EAc4 - Enhanced refrigerant management" "In the calculation of EAc4, is it acceptable to count the quantitative cooling loads addressed directly by the direct/indirect evaporative cooling units, that would otherwise be met with chillers, so that the refrigerant in walk-in refrigerators is not given an unfair weight in the calculations?" "As the walk-in refrigerators are not part of the base building HVAC systems they are excluded from the requirements of this credit, provided that the total capacity of this equipment represents less than 15% of the total building installed HVAC capacity.\n\n **Update October 1, 2013: Per the rating system requirements, all refrigeration included as part of the scope of work of the project, and having more than 0.5 pounds of refrigerant must be included in the EA Credit 4 analysis, not matter what percentage of the overall HVAC capacity. This interpretation only allows exclusion of walk-in refrigerators that are not part of the base building (meaning that these systems are outside of the scope of work of the project)."
