Clothing Wear and Tear of Heat Pump vs. Electric Clothes Dryers with Addendum
Heat pump clothes dryers are significantly more energy efficient than conventional (ENERGY STAR®) electric resistance clothes dryers. The goal of this project was to determine whether heat pump clothes dryers offer non-energy benefits—specifically, reduced clothing wear and tear—that could help consumer adoption. Multiple machine types ran over 100 dryer cycles, using loads specifically chosen to…

Revising the TV Energy Use Test Procedure: Incorporating HDR and other Needed Changes
The measurement method of television energy consumption has been largely consistent within the United States for the last decade. TVs have improved remarkably in energy efficiency during that time. It is important to understand how much of those apparent energy savings are the result of fundamental improvements to TV technology itself versus optimizing how TVs…
