The Elephant in the Laundry Room
Today, the ENERGY STAR standard represents a minimum 20% improvement in energy efficiency over the standard clothes dryer with the most efficient large (7.4 cubic feet) clothes dryer using only 556 kWh per year and the most efficient smaller (4.1 cubic feet) clothes dryers using an impressive 149 kWh per year. ENERGY STAR has introduced a Combined Energy Factor (CEF) metric to help buyers compare models that have different total energy consumptions and the size of the clothes dryer. Using this metric, the smaller dryers represent the highest overall efficiency with a CEF of 5.7, while the larger dryers top out at a CEF of 4.3.
Look out for a new Earth Advantage home certification measure for ENERGY STAR clothes dryers in the next iteration of the program, which will be released in 2019. Our experience has shown an appliance upgrade can make the difference between Zero Energy and Platinum certification! Be sure to consider this technology when pursuing your next Zero Energy Ready home.
