FAQs about EAp3 :

If a project’s base-building systems do use CFCs, and an economic analysis is required, is it necessary to analyze both the conversion AND replacement of those building systems?

The LEED Reference Guide states that if CFCs are maintained in the building, the project building must reduce annual leakage to 5% or less, and total leakage over the remaining life to less than 30%. However, the EAp3 credit form does not request informat

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 EAp3?

EBOM-2009 EAp3:Fundamental Refrigerant Management

DHC Plant with CFC refrigerant

Our project is served by district heat and cilled water plant. The plant, owned by different componay from our project owner, uses CFC refrigerant for some of chillers. It is difficult to do feasibility study for replacement of equipment by ourselves as well as to request the plant owner company to write a phase out plan. Is it possible for our project to meet this prerequisite requirement?

Per the District Energy Guidelines for EBOM, when a third party owns the district energy system, the EAp3 and EAc5 requirements apply to the downstream equipment but not the upstream equipment. So you're not obligated to try to convince a different company to change the way they do business with refrigerants. So, as long as you meet all of the EAp3 requirements for your own downstream equipment and make reference to the district energy guidelines, you will have the opportunity to meet this prerequisite.

Noriko, I'm not sure I understand your question. Are you talking about a LEED-CI certification within the LEED-EBOM certified building? That would depend on the specifics.
