EQUIPMENT INVENTORY
Project teams must identify all refrigerant-containing equipment included in the scope of work, including any existing equipment within the project boundary owned or controlled by the project owner and/or facilities manager. 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 non-comprehensive list of the types of refrigerant-using equipment that a project’s scope of work may include.
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.
