Hi Alison, you are right this is a design credit and can be submitted during design phase. For ‘Installed’ date you can put an approximate date the air conditioning equipment will be installed. The field is useful for the review team to estimate available refrigerants at the time of installation. This credit covers all projects including major renovation that may have existing systems.
My project team decided to commit to LEED certification under the NC rating system after our design was completed and scope was purchased. Can the construction team respond to the fundamental phase out requirements referenced in EAp3 (FYI-our MDF Liebert units were designed to use R22 and were purchased 1 year ago)?
