CI-2009 EAp3:Fundamental Refrigerant Management

May 2011 Addenda - CFC Phaseout Plan

In the May 2011 Addenda to this credit, the references to a CFC Phaseout Plan have been removed. Specifically: Pg. 148 Location: Economic Issues Remove the last two sentences of the section, beginning with, "If savings offset costs…" to, "economically infeasible" Pg. 149 Location: 5. Timeline and Team Remove the second sentence, "If CFC-based refrigerants are located, the building owner should develop a phase-out plan and convert to less environmentally harmful refrigerants." Since the credit states that only HVAC systems built for the project are within the scope of this work, would this simplify the interpretation to "Don't install CFC-based refrigeration equipment"?

Michelle, I do think that sums it up, yes.

I'm looking at this prereq right now and need to verify what the May 2011 addenda states. Note that it was accompanied by the following change in the Rating System language under Potential Technologies & Strategies: When reusing existing HVAC systems, conduct an inventory to identify equipment that uses CFC-based refrigerants and replace or retrofit these systems with non-CFC refrigerants. this is confusing as to whether an inventory and replacement of refrigerants for reused/existing equipment (in this case from a central plant) is a requirement or not - some help?

Michele, I'm not seeing the change you are referring to. Are you sure you're looking at ID&C addenda? They can be downloaded here.

You can also search for addenda through the interpretations page (https://www.usgbc.org/leedinterpretations/lilanding.aspx). At this point, inventory and replacement for base building equipment that is outside of the CI scope of work is not required. The credit form doesn't ask for any basebuilding information, either.

looks like the language was added for the 2009 version but basically, I'm referring to the fact that the Rating System language under Potential Technologies & Strategies is inconsistent with the actual requirements - it's probably left over from the May 2011 addenda that removed the inventory requirement. But thanks Ante for the clarification !

Hi all, I'm still a little unclear on this issue. Ante, are you saying that if the project is a complete gut & remodel, and the base building equipment could therefore be considered inside the scope of work, we would be responsible for removing CFCs, but if the base building equipment is outside of our scope, we do not need to address it? As Michele mentions, the LEED-CI Rating System - which was updated in 2012 after the addenda - states "when reusing existing HVAC systems, conduct an inventory to identify equipment that uses CFC-based refrigerants and replace or retrofit those systems with non-CFC refrigerants." This still seems to imply we're on the hook for any existing CFCs, so I'm a bit apprehensive to advise my team that they're okay leaving CFC equipment in the base building. Thank you!
