EPA Proposes Updates for ENERGY STAR Most Efficient Program

Fri, 09/09/2016 - 10:27 -- MrGreen

The U.S. Environmental Protection Agency (EPA) recently proposed new requirements for its 2017 Most Efficient (ME) product program. Currently for 2016, the program promotes the highest efficiency ENERGY STAR qualified products within twelve product categories; boilers, ceiling fans, central air conditioners and heat pumps, clothes washers, computer monitors, dishwashers, furnaces, geothermal heat pumps, refrigerators/freezers, televisions, ventilating fans, and windows.

For 2017, the EPA will retain eleven of those categories and add a new one. Televisions will drop off the ME list temporarily due to the EPA’s investigation into the impact of additional energy saving features found in new models. (For more info on this, see EPA Launches ENERGY STAR Television Spec Version 8 Development.) Clothes dryers will be added in 2017, with criteria for both normal and highest energy-consuming settings.

Based on recent testing of ENERGY STAR products, the EPA decided that most product categories would retain their 2016 requirements for 2017. Computer monitors, however, will see a tightening in the efficiency criteria for high resolution product.

A computer monitor’s annual Total Energy Consumption (kWh/yr) is calculated using the following equation:

ETEC = 8.76 × (0.35 × PON + 0.65 × PSLEEP)

Where: PON = measured on mode power (W), PSLEEP = measured sleep mode power (W)

A monitor’s ETEC must be less than or equal to the maximum allowable annual Total Energy Consumption (kWh/yr) calculated using the following equation:

ETEC_MAX = 6.13 × r + 55 × tanh (0.003 × [A − 59] + 0.01) + 5.0

Where: A = viewable screen area (in in2), tanh = hyperbolic tangent function, and r = Total Native Resolution (TNR) in megapixels, up to 5.0 megapixels total. New for 2017, is a limit of 5.0 for products >5.0 megapixels, resulting in a maximum resolution allowance of 6.13 × r, or 30.65.

The EPA will hold a stakeholder webinar to discuss the proposed 2017 program specifications on September 12th from 1:00 PM to 3:00 PM, Eastern Time. To register for the webinar, click here.
