Equipment inventory Project teams must identify all refrigerant-containing equipment in the LEED ID+C: Commercial Interiors project, including new equipment installed in the project scope and any existing equipment within the project boundary, owned or controlled by the tenant. Equipment that contains less than 0.5 pounds (225 grams) of refrigerant, such as standard residential refrigerators in dwelling units, can be excluded from the calculations.
Manage the inventory during the construction phase. If equipment substitutions occurred during the submittal and procurement phases, update the inventory to reflect the actual installed equipment.
Table 2 is a sample and noncomprehensive list of the types of refrigerant-using equipment that may be included in a project’s scope of work.
A refrigerant inventory for the complete building is acceptable in lieu of a project-specific inventory. Ensure that the inventory is updated with any new equipment installed within the project scope.
Additional considerations — equipment inventory Completing the inventory in the Construction Documents phase provides owners and design professionals with a complete understanding of the future climate impacts.
