New air conditioner standards will reduce cooling costs for modular classrooms and offices
Posted by Joanna Mauer on September 11, 2015

New energy efficiency standards for certain types of specialized air conditioners will reduce cooling costs for many schools as well as other buildings. The new standards issued by the US Department of Energy (DOE) last week will cut cooling energy use by about 18% relative to the current standards.

The final rule sets new minimum efficiency levels for single-package vertical air conditioners and heat pumps, which are commonly used to cool modular classrooms and offices and...

Using less energy to keep drinks cold
Posted by Joanna Mauer on August 05, 2015

Late yesterday, the Department of Energy (DOE) proposed strong new standards that would reduce the energy consumed by beverage vending machines to keep drinks cold. The proposed standards would cut energy use by 25-65% relative to the least-efficient machines available now, and save money for schools, hospitals, hotels, and other businesses and institutions where beverage vending machines are used.

Beverage vending machines meeting the new standards, sold...

Hot food, less energy waste with new efficiency standards
Posted by Joanna Mauer on June 01, 2015

The US Department of Energy (DOE) proposed new efficiency standards today for kitchen ovens that would improve cooking efficiency and reduce “vampire” energy waste. The proposed standards would cut energy use by 3-12% for electric ovens and 11-33% for gas ovens relative to today’s baseline products. 

DOE estimates that ovens meeting the new standards sold over 30 years would reduce national energy consumption by 700 trillion Btus, an amount equal to the annual energy...

Taming the other energy hog lurking in your basement
Posted by Joanna Mauer on May 14, 2015

Last summer, the U.S. Department of Energy (DOE) issued new efficiency standards for furnace fans, which are a little-known energy hog that may be lurking in your basement. Today, DOE proposed new standards that would help tame another energy hog that may be in your basement—dehumidifiers. However, while the proposed standards would be a good step towards cutting dehumidifier energy...

Proposed pump efficiency standards reflect industry, advocate consensus
Posted by Joanna Mauer on March 18, 2015

The U.S. Department of Energy (DOE) proposed new efficiency standards yesterday for commercial and industrial pumps that are based on efficiency levels negotiated by manufacturers, efficiency advocates, and other stakeholders. The proposal would establish the first-ever national efficiency standards for pumps.

The proposed standards would apply to clean water pumps between 1 and 200 horsepower, which are used for a wide variety of applications such as irrigation, circulation of hot or cold...

New efficiency standards would help address heating bills of many homes in cold climates
Posted by Joanna Mauer on March 16, 2015

On the heels of a proposed rule for new efficiency standards for furnaces, late on Friday the US Department of Energy (DOE) issued a proposed rule for another type of home heating equipment. While the proposed standards for boilers would save money for many consumers in cold climates, higher standards could achieve significantly greater energy savings.
