John speaks with Clay Nesler about building energy efficiency, especially how it ties to economic recovery and resilience in the face of the global COVID-19 pandemic. Their discussion includes some of the various efficiency standards throughout the world and different approaches to retrofitting existing buildings.
Buildings — with their thirst for electricity, natural gas, and fuel oil — are a major contributor of atmospheric carbon. However, the building stock in the United States turns over, on average, every century, meaning today’s carbon emission output cannot be resolved without deep changes in existing buildings. The task is transformation. The challenges are
Drew Turner, Global Marketing Manager for Oil-free Solutions at Danfoss, joins host John Sheff in this episode of the Envisioneering Exchange podcast for a dialogue about the decarbonization policies in North America, and the role played by oil-free compressor and heat pump technology in meeting emissions targets and electrifications goals.
Host John Sheff interviews, Peter Dee, Danfoss’ Sales & Services Director for Food Retail in North America, about refrigerant trends in food retail applications, such as using alternative refrigerants, particularly natural refrigerants like CO2. Further they detail on what new and existing technologies are available to support an efficient, cost-effective transition to natural refrigerants, and the impact of refrigerant regulations.
In this episode of the Envisioneering Exchange podcast, host John Sheff and guest Vic Marinich, the Global Marketing Director for Air Conditioning at Danfoss, take a look at the current landscape of refrigerants for air-conditioning applications (from R-22 to R-410A, to R-134a and beyond). Later in the podcast, they discuss the phasedowns of high-GWP refrigerants as well as the emergence of flammable and mildly flammable refrigerants.
Host John Sheff, Danfoss’ Director of Public Affairs, has Dean Groff, Danfoss Food Retail Services Contractor Manager, back to discuss flammable refrigerants, their regulations, and how to safely handle them.
Welcome to the debut episode of the Envisioneering Exchange podcast. In our first episode, host John Sheff, Danfoss’ Director of Public Affairs, and guest Dean Groff, Danfoss Food Retail Services Contractor Manager, discuss the current landscape of refrigerants and the impact of US and Canadian regulations (American Innovation in Manufacturing Act, SNAP, CARB, Climate Alliance).
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
In the previous post, we looked at the global path to a safe transition to low-GWP refrigerants, and the impact that actions by states like California are having on creating a patchwork of regulations and move us toward the use of highly flammable refrigerants. Here, I trace how the move impacts standards and codes, as
The global transition to low-GWP refrigerants is beginning in a disorderly manner in the United States — the world’s most mature HVAC market. In the absence of a federal framework, individual states are beginning to regulate HFCs. A handful of states are following SNAP Rules 20 and 21, the EPA regulations that were vacated by
