Air source heat pumps seem like magic when they turn one unit of electricity into two, three, or even four units of heat moved. But did you know there's an... Learn More
Recent regulatory changes came into effect in 2025 impacting the allowable Global Warming Potential (GWP) of refrigerants. These changes come with new requirements for how refrigerant-based systems are handled and installed, leading to complications, opportunities, and emerging best practices for equipment selection, architectural and mechanical design, and electrification solutions. This panel will feature manufacturers, consultants, and design professionals discussing how these changes are already rippling out through the design and construction markets and what we may expect to see in emerging design and electrification trends as a result.
Panelists include:
Prior to this, she worked as Vice President Regulatory Affairs at The Air-Conditioning, Heating, and Refrigeration Institute. Helen has also worked in Regulatory Affairs at The Chemours Company and Sourcing Planner at DuPont.
