Using Less Energy to Keep Drinks Cold

American Council for an Energy-Efficient Economy, Aug. 5, 2015, by Joanna Mauer.

"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."

Slash Plug Loads in 6 Steps

Buildings, Jan. 2015, by Janelle Penny.

"Plug loads are becoming one of the fastest growing end uses of energy, the New Buildings Institute warns, and their drain on energy budgets is on the rise. [Plug load] includes any devices that plug into a building’s electrical system. In a typical office, the worst offenders are desktop equipment such as computers, monitors, and printers, notes Suzanne Foster Porter, director of research and technical services for ECOVA, an energy and sustainability management firm. Small offices also see a disproportionate amount of their plug load stemming from IT closets and computer rooms."

Gaming Consoles Deliver Excitement, Value for the Energy Buck

Electric Power Research Institute (EPRI), Dec. 2014, by Clay C. Perry.,-Value-for-the-Energy-Buck.aspx

"An EPRI research team compared the energy consumption of the Microsoft Xbox One, Sony PlayStation®4 (PS4), and the Nintendo Wii U consoles while running the popular game Call of Duty®: Ghosts. In a head-to-head, hour-long test – the Wii U consumed 30 watt-hours (Wh) of electricity. Xbox One measured in at 105 Wh, and PS4 weighed in at 124 Wh."

Rulemaking for Commercial and Industrial Fans and Blowers

U.S. DOE, EERE, Building Technologies Office, Appliance & Equipment Standards, Jan. 12, 2015.

"DOE published a Federal Register notice of comment period extension for the notice of data availability regarding energy conservation standards for commercial and industrial fans and blowers. 80 FR 1477 (January 12, 2015). The comment period has been extended until February 25, 2015."

New Standards to Improve Efficiency of Clothes Washers in Laundromats and Apartments

Appliance Standards Awareness Project, Dec. 8, 2014, by Joanna Mauer.

"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 Denies Petition; AHRI Sues Over Rule

Air Conditioning, Heating, Refrigeration News, Oct. 13, 2014, by Jen Anesi.

"On Sept. 23, the U.S. Department of Energy (DOE) denied a petition from Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and Lennox Intl. Inc. that asked the government agency to reconsider its June 3 final rule establishing energy-conservation standards for walk-in coolers and freezers (WICF). AHRI and Lennox, who argued the final rule was promulgated unfairly and contained nearly unattainable efficiency standards, filed the petition for reconsideration on July 30 in hopes the DOE would review its WICF final rule without the need for court intervention."

Take Care in the Kitchen: Avoiding Cooking-Related Pollutants

Environmental Health Perspectives, Jun. 2014, by Nate Seltenrich.

"Researchers now understand that the process of cooking food and even simply operating stoves—particularly gas appliances—can emit a cocktail of potentially hazardous chemicals and compounds. Within our homes, these pollutants are less diluted than they are outdoors, and in the absence of proper ventilation, they often are trapped inside."

Includes a discussion of the kitchen ventilation requirements in ASHRAE 62.2.

The Impact of Transactive Energy on Appliances

Appliance Design, Apr. 2014, by Dr. Kenneth Wacks. (Free registration required to view full article.)

"Transactive Energy (TE) combines market forces and control techniques to achieve grid balance. Since renewable power from sources fluctuate, TE seeks to adapt customer equipment demands for power."

New Refrigeration Efficiency Standards To Take a Bite out of Supermarket and Restaurant Energy Costs

American Council for an Energy-Efficient Economy (ACEEE), Feb. 28, 2014, by Joanna Mauer.

"The Department of Energy (DOE) issued a final rule for strong new efficiency standards today that will take a big bite out of the energy consumption of the refrigerators and freezers used in supermarkets, convenience stores, restaurants, and commercial kitchens. The significant reductions in energy use that we’ll see with the new standards are made possible by the availability of technologies including LED lighting and occupancy sensors, high-performance glass doors, and high-efficiency motors, which all provide big efficiency gains." Includes a link to the final rule.

Site Assessment for Solar Water Heating Systems

Home Power Magazine, Feb./Mar. 2014, by Vaughan Woodruff.

"Without a proper site assessment, you may be putting your solar thermal system at risk for poor performance."
