The Path to a Safe Refrigerant Transition: It’s Coming Whether We’re Ready or Not

A safe transition to low-GWP refrigerants in the US is made more complex by the Montreal Protocol, the original international treaty finalized in 1987 to phase down Ozone Depleting Substances, or ODS, which included HFC predecessors CFCs and HCFCs. The Kigali Amendment to the Montreal Protocol amended the international treaty in 2016 to reduce greenhouse

Are we Getting Closer to Allowing the Use of Flammable Refrigerants?

One of the barriers to the new refrigerants is the recognition of flammable refrigerants in building codes. Codes dictate so much about building construction and what mechanical equipment can be used. There are codes for fire protection, building construction, mechanical systems, and other aspects of buildings; all affect the HVACR system. A good article on

The Role of Design in Innovation and Sustainability

Henry Ford once said, “You can have any color you want as long as it’s black”—a slogan that launched the early industrial model. And still today industry relies on economies of scale—and scaling means as little product differentiation as possible within a product line. Industrial efficiency thrives on product commoditization, but in a competitive global
