We have a project with a central plant with chillers that has R-11 refrigerant. An economic analysis has been performed by a 3rd party that states it is not economically feasible to replace the chillers within 10 years. We will also be providing documentation stating the leakage of the refrigerant is less than 5%.
Besides the backup documentation for the economic analysis and leakage rates, is there any additional information that needs to be provided? Has anyone used this compliance path and can provide us any details on comments GBCI has made during the review that can help us prepare to submit this prereq? We want to be sure we don't encounter any issues during the review, and if necessary, provide more documentation up-front to prevent any issues. Thank you in advance.
