include refrigerant-using equipment installed as part of the tenant scope of work if tenants specify the equipment on their construction documents. When including tenant equipment, include all refrigerant-using equipment specified on the tenant drawings.

OPTION 2. LIMIT REFRIGERANT LEAKAGE

Include at least 20% of the total predicted heating and cooling generation capacity in the project’s scope of work for the base building.

Example 1: Eligible project An owner pursues LEED BD+C: Core and Shell certification for a speculative office and laboratory base building. The base building systems include chillers, central air handling units, and laboratory exhaust fans. Through energy modeling or load calculations, the project team confirms that the total heating and cooling generation capacity exceeds 20% of the total predicted capacity. The building is eligible to pursue this credit and document compliance for the systems within the scope of work.

Example 2: Non-eligible project An owner pursues LEED BD+C: Core and Shell certification for a speculative office building. The scope of work is limited to a cold, dark shell. The project excludes base building systems and cannot pursue this credit.

District Energy Systems

OPTION 1. NO REFRIGERANTS OR LOW GWP REFRIGERANTS

Path 1. No Refrigerants

Refrigerants cannot be used to generate any district energy source serving the project. Teams connected to a DES for any energy source should work directly with their provider to determine if compliance is met for this option.

Path 2. Low GWP Refrigerants

Teams can elect to include the refrigerant impacts from the DES when compliance cannot be demonstrated based solely on new equipment within the project scope.

Where teams include DES equipment within the calculations, account for all new and existing equipment containing refrigerant from all district energy sources serving the project. Teams
