Plug & Process Loads
Plug & Process Loads
Plug and process loads (PPLs) consume about one-third of primary energy in U.S. commercial buildings. As buildings become more efficient, PPL efficiency has become pertinent in achieving aggressive energy targets. Through the PPL Technology Research Team, partners participate in a platform to share experiences and learn from their peers, and work together to create resources on PPL energy reduction strategies and their applications, covering a wide variety of electronic, computer, refrigeration, and cooking devices, including equipment essential to information processing, medical treatment, and food service businesses.
The Plug and Process Load Team has hosted many webinars about a variety of PPL-related topics. Access all the recordings and slide decks in the On-Demand Webinar Library.
The Plug and Process Load Team collaborates with researchers and industry experts to promote awareness and energy reduction through new technologies. Contact the Plug and Process Load Team to learn how you can get involved.
The Better Buildings, Better Plants Summit is transitioning to a virtual leadership symposium, taking place June 8-11, 2020. Experience 4 days of sessions, workshops, recognition, and more with industry experts and peers.
Office Building Plug Load Disaggregation Case StudyWith thousands of devices in today’s large buildings, individually monitoring every plug load becomes a nontrivial task. To address this, researchers at NREL proposed a method for combining a limited amount of smart plug metering with a device inventory to develop a disaggregated breakdown of device-level power consumption.

Policies and Incentives
PPL Team Quarterly Update
Learn about recent activities and upcoming events from the Plug and Process Load Tech Team.
Low Voltage Distribution Transformer Calculator
Install a distribution transformer that will reduce energy use by more than 15% using this calculator from DOE.
Consortium for Energy Efficiency: Distribution Transformer Initiative
The purpose of this Initiative is to drive market demand for high efficiency through assisting member programs to overcome barriers like first cost, split incentives, and absence of a consistent definition for high-performance.
DOE Appliance and Equipment Standards Program
The Building Technologies Office (BTO) implements minimum energy conservation standards for more than 60 categories of appliances and equipment. This program provides a resource to help consumers make informed decisions when selecting products in order to save energy and money.
Meet the Technology Expert
Dr. Kim Trenbath is a Research Engineer in the Buildings and Thermal Sciences Center at the National Renewable Energy Laboratory, where she has worked since 2013. She leads the Better Buildings Plug and Process Loads Technology Research Team and researches how advanced technologies can reduce plug load energy use in commercial buildings. Her other current research includes fault detection and diagnostics and zero energy buildings. Dr. Trenbath co-manages the ongoing buildings-related JUMP into STEM student competition. Dr. Trenbath has a Ph.D. in Atmospheric Science, a M.S. in Industrial Engineering, and a B.E. in Civil Engineering. Dr. Trenbath is also an adjunct professor at the Colorado School of Mines.
