The refrigerant type I need to enter is missing from the credit form. What should I do?

USGBC has instructed teams facing this issue to use the LEED v2009 sample form to complete the refrigerant impact calculation, which can be downloaded from the USGBC LEED Credit Library. This form includes a choice of 'other' where you can insert a new refrigerant type along with the associated ODP and GWP values. You’ll need to include a brief narrative in the Special Circumstances box on the LEED v4 credit form and upload the completed sample form. Since it’s up to you to identify ODP and GWP values for the new refrigerant, you’ll need to provide supporting documentation for these values so that the reviewer can confirm their accuracy.
