FAQs about EAc5 :

Can a project use default leakage rate values or leakage values specified by the manufacturer for equipment rather than actual leakage rate values based on the credit calculations?

Do small appliances (such as refrigerators and water coolers) that have greater than 0.5 pounds of refrigerant have to be included in order to achieve EAc5?

EBOM-2009 EAc5:Enhanced Refrigerant Management

Performance period for leakage rate

I'm wondering what performance period would be acceptable for calculating the leakage rate (lbs of refrigerant added and over what time frame) for this credit. For instance, does the period over which the leakage rate was calculated also have to end within 30 days of all other credits? Or can the leakage rate be based on, say, the first 6 months of a 1 year performance period.

Hi Emily, Based on the v5 form, the leakage rate needs to be annualized rate and so the best would be to see how much leakage was experienced in the past year. I don't think extrapolating partial year data would typically work since we're required to report actual leakage rates.

Ok - say I only have data for the amount of refrigerant added over a period longer than one year. Is it acceptable to extrapolate from that to a period of a year while maintaining the same actual leakage rate? Example: 100 lbs added after 18 months = 67 lbs after 12 months?

Sorry, I think I got it. If no refrigerant was added in the last year, we can just use the 0.5% default leakage rate. Correct?

That's right, if there was no refrigerant leakage in the past year then you can use the 0.5% default. You'll need to include a narrative along with the credit indicating that the leakage was tracked and there was no refrigerant added.
