Intent
To reduce stratospheric ozone depletion.Requirements
Do not use chlorofluorocarbon (CFC)-based refrigerants in heating, ventilating, air-conditioning, and refrigeration (HVAC&R) systems unless a third-party audit shows that system replacement or conversion is not economically feasible or unless a phase-out plan for CFC-based refrigerants is in place. Phase-out plans should be scheduled for completion within 10 years. The replacement or conversion of HVAC&R equipment is considered not economically feasible if the simple payback of the replacement or conversion is greater than 10 years. Perform the following economic analysis: If CFC-based refrigerants are maintained in the project, reduce annual leakage to 5% or less using the procedures in the Clean Air Act, Title VI, Rule 608, governing refrigerant management and reporting (or a local equivalent for projects outside the U.S.), and reduce the total leakage over the remaining life of the unit to less than 30% of its refrigerant charge. Small HVAC&R units (defined as containing less than 0.5 pound [225 grams] of refrigerant), standard refrigerators, small water coolers, and any other cooling equipment that contains less than 0.5 pound (225 grams) of refrigerant are exempt.

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 answer to this question is available to LEEDuser premium members.

The prerequisite 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%. Do we need to submit documentation demonstrating the leakage raThe answer to this question is available to LEEDuser premium members.

What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
