Irvine, December 6, 2017 — At an early age we are taught that it is important to turn things off when not in use. Now, it’s more complicated: roughly 50 devices and appliances in the typical American household are always drawing power, even when they appear to be off, according to a U.S. Department of Energy report. These so-called plug load devices – products that are powered by means of an ordinary AC plug – are the focus of UC Irvine’s CalPlug research center.
The unique facility was established to improve energy efficiency in the use and design of these proliferating devices. By all estimates, the number and energy intensity of plug-in devices will increase to 30% of total U.S. energy use by 2030. Critical to CalPlug’s success is its partnerships with government agencies, manufacturers, retailers, NGOs and utility companies. Initial funding came from the California Energy Commission and the center is now supported by member companies and funded research activities
A dozen LADWP engineers visit CalPlug this fall to further collaborations.
“CalPlug focuses on energy efficiency solutions, efficiency evaluations of consumer electronics, standards development, user-behavior studies, and education and public outreach,” said G.P. Li, the Center’s director.
In 2012, CalPlug began collaborating with the Los Angeles Department of Water and Power, the largest municipal utility in the country. The initial partnership was led by David Jacot, LADWP director of efficiency solutions, and Amir Tabakh, chief of efficiency solutions engineering & LADWP La Kretz Labs. In a recent visit to UCI, twelve LADWP engineers met with CalPlug researchers to delve further into future opportunities.
“We want to partner with UCI because you are researching innovative solutions for plug load energy efficiency,” Tabakh told the CalPlug team. “It is very important to focus our attention on this critical area of mutual interest as household population grows in southern California, so too will the energy demand.”
Educating consumers is key to improving energy consumption behavior. CalPlug routinely demonstrates prototype development, and welcomes partner companies to showcase their products and technologies in the Center. During their visit, the LADWP engineers saw a dizzying array of activity.
Projects showcased included:
In addition to demonstrations, CalPlug regularly hosts workshops and events to maximize communication of the latest research findings. Typical events include experts from different sectors to ensure informed decisions and actions on technology and business development. Among the many outcomes, collaborators hope efforts will help new construction and developers attain zero net energy code and standards mandates by 2020 and 2030 for residential and commercial buildings, respectively.
Ultimately, the goal is to bring awareness of, and solutions for, the burgeoning plug load devices that are guzzling power even when they are not in use.
“Consumer education and adoption is the key to reducing energy consumption,” Li explained to the LADWP engineers. “Collaborations with partners like you will lead to rate payers making more informed decisions and saving a lot of energy and money.”
