Advanced Refrigeration - ARS2022001

Audit Analysis

A straightforward one-time refrigerant replacement project (R-22 HCFC to low-GWP) in North Carolina, validated by Ruby Canyon Environmental under ACR's Advanced Refrigeration methodology v2.1. Additionality is confirmed via a combined test and the permanence profile is inherently strong because the reductions are fixed once the low-GWP refrigerant is installed. Main weaknesses are the project-specific baseline, a 0% leakage deduction justified only as 'deemed negligible,' and low extraction confidence across the document set.

Project Description

Red Flags

• ⚠Leakage deduction is 0% with only a 'deemed negligible' justification; no quantitative analysis of potential refrigerant leakage over the 10-year crediting period is documented in the validation report.
• ⚠The GWP value used in the initial ER calculation was incorrect (AR4 value instead of the required AR5 value of 1,710); the error was caught and corrected during validation, but it signals a quality-control gap in the project developer's methodology application.
• ⚠Low extraction confidence across the document set means at least one key document was poorly readable, limiting the depth of verification possible.
