My understanding is that the minimum acceptable Leakage Rate is 0.5%, even if the actual data demonstrate a lower leakage rate. The v4 form accommodated this by allowing the Lr to be manually entered but the v5 form only auto-calculates the Lr based on the amount of refrigerant added. If I have units that have not had any refrigerant added within the past year, how can I use a leakage rate that LEED accepts while still reporting accurate data on refrigerant added? Has anyone else experienced this problem?

Hi Andy,
Your understanding about the minimum leakage rate is correct. Can you trick the v5 form by adjusting the amount of refrigerant added until the Lr is 0.5%? That may work.

Hi Andy,
I like Ben's suggestion to add refrigerant until an Lr of 0.5% is reached. Another option is to fill out a v4 form and upload it along with a narrative describing the issue with the v5 form.

I am trying to find the v06 form per GBCI response to inquiry; Does anyone know where this v06 form is? I have not been able to find it and would really appreciate a suggestion.
Thank you for contacting GBCI. For projects with no refrigerant added, the recently released v06 form for EAc5 enforces a minimum 0.5% leakage rate without requiring the project team to enter an alternative amount for pounds of refrigerant added. The project team should enter 0 pounds in this case. If using a prior version of the form, the only workaround is to enter the pounds of refrigerant added that corresponds to 0.5% of the total refrigerant charge.

Hi Kimberly, you can download the v06 form for EAc5 here: http://www.usgbc.org/node/1731233?return=/credits/existing-buildings/v2009.

Thank you for the link to the new form. It works but unfortunately it can not yet be used to submit yet see comment on form: "This active sample form is for your recertification reference and preparation work. It has not gone through USGBC's testing and quality control process and cannot be used to submit for recertification. If you have any comments or concerns with the functionality of the form, please submit a brief explanation using the Feedback button in LEED Online." Maybe it will be ready soon. It is a good check though.
