DOE proposes first update to commercial furnace standards in 20 years
Posted by Joanna Mauer on January 16, 2015

The U.S. Department of Energy (DOE) proposed new standards today that would provide a modest boost to the efficiency of commercial furnaces. The standards for commercial furnaces are due for an update as they have not changed in more than 20 years.

Commercial furnaces are typically used to provide space heating for low-rise buildings such as schools, restaurants, big-box stores, and small office buildings. (Larger buildings generally use boilers to heat hot water that is...

Dishwasher energy and water use would continue to decline with new efficiency standards
Posted by Joanna Mauer on December 11, 2014

The U.S. Department of Energy (DOE) proposed strong new efficiency standards today for dishwashers that would reduce energy and water use by 24% and 38%, respectively. The new standards would save money for consumers on their utility bills and help continue the 25-year trend of declining dishwasher energy and water use.

DOE estimates that the new standards would save 1 quadrillion Btus of energy over 30 years of sales, an amount equivalent to the annual energy use of almost six million U...

New standards to improve efficiency of clothes washers in laundromats and apartments
Posted by Joanna Mauer on December 08, 2014

The U.S. Department of Energy (DOE) issued new efficiency standards today that will reduce the energy and water use of commercial clothes washers, which are used in laundromats and multi-family buildings.

DOE estimates that the new standards will net a typical owner of a commercial clothes washer $165 to $290 in savings over the life of the machine. On a national level, the new standards will save 70 trillion Btus of energy over 30 years of sales, an amount...

The good news, and the not-so-good news, on the new DOE water heater test procedure
Posted by Anthony Fryer on June 30, 2014

On Friday, the Department of Energy (DOE) issued a new test procedure for residential and some commercial water heaters. The new procedure addresses a number of longstanding testing issues in order to better replicate real-world usage and to more accurately measure energy consumption across various technologies. Unfortunately, DOE missed an opportunity to ensure that one of the most energy-efficient technologies, the electric heat pump water heater (HPWH),...
