There’s a global movement, circa 2016, via the Kigali Amendment of the Montreal Protocol, to transition away from HFC refrigerants that have high Global Warming Potentials (GWP) to alternatives that are better for the environment. For those in Maryland and Virginia, the date you should be familiar with regarding codes and standards changes is January 1, 2024 – which is right around the corner.

Trane has already been working to implement changes earlier than these mandates and regulations came into effect.

What Considerations Are There in Transitioning from High HFC Refrigerants to GWP Solutions?

  • Total cost of ownership and energy efficiency of the entire system:

    • Efficiency of equipment selection and capabilities

    • Operation of your equipment through building automation systems

    • Maintenance of refrigerants, tracking replacement, and completing proper documentation for annual emissions reporting

  • Environmental impacts, such as Lowest Green House Gas (GHG) emissions

  • Safety in utilizing lower GWP refrigerants, including toxicity, flammability, asphyxiation, and physical hazards
