Intent

To reduce ozone depletion and global warming potential and support early compliance with the Kigali Amendment to the Montreal Protocol while minimizing direct contributions to climate change.

Requirements

Do not use chlorofluorocarbon (CFC) or hydro chlorofluorocarbon (HCFC)-based refrigerants in new heating, ventilating, air-conditioning, and refrigeration (HVAC&R) systems. When reusing existing HVAC&R equipment, complete a comprehensive CFC and/or HCFC phase-out conversion before project completion. Phase-out plans extending beyond the project completion date will be considered on their merits. Existing small HVAC&R units (defined as containing less than 0.5 pound [225 grams] of refrigerant) and other equipment, such as standard refrigerators, small water coolers, and any other equipment that contains less than 0.5 pound (225 grams) of refrigerant, are exempt.

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.

Description of change:
1. Delete the phrase "There are no substantive changes to prerequisite requirements;", capitalize the R in "Refer", and add the words "edits and" after the words "with the following".

2. Add new section "Behind the Intent:". Below the section header add the following text:
"Hydrochlorofluorocarbons (HCFCs) have shorter atmospheric lives than CFCs, but they still contribute to ozone depletion. Similar to CFCs, HCFCs have phase-out dates scheduled under the Montreal Protocol.

Both HCFCs and CFCs must be addressed to meet this prerequisite."

"Wherever CFCs are mentioned in the LEED v4 reference guide, the guidance also applies to HCFCs."
