If you are considering smart outlets for your lighting integration project, the National Renewable Energy Laboratory has published a resource that answers common questions and explains the benefits. Smart outlets control the flow of power to devices plugged into them and measure their energy use. These outlets collect control and energy data, which are then sent wirelessly, often via an intermediate gateway, to a cloud database or the building’s energy management system (EMS). With the help of machine learning algorithms, the collected data could be used to predict schedules and save energy. Plug and process loads (PPLs) consume about 47% of primary energy in U.S. commercial buildings. As buildings become more efficient, PPL efficiency has become pertinent in achieving aggressive energy targets.

The project provided a packaged solution for a retrofit of the lighting, including site survey, design, system selection, and financial assistance with materials and labor.
The city of St. Paul upgraded about 13,100 ft2 of its Street Maintenance Division building with a new networked light emitting diode (LED) lighting system integrated with heating, Ventilation, and Air Conditioning (HVAC ) and plug load controls. The city installed the lighting and plug load controls and worked with a lighting manufacturer to commission the networked lighting control system. A local HVAC controls contractor was hired to integrate the lighting with the HVAC system.
The county partnered with Slipstream–a non-profit focused on energy efficiency and climate solutions–to integrate lightemitting diode (LED) lighting with luminaire-level lighting controls (LLLCs), automatic receptacle (plug load) controls, and zoned heating, ventilation, and air conditioning (HVAC) controls in one floor of a multi-story building in downtown Minneapolis. The floor is occupied by an outpatient clinic and a fitness center; both are served by a common variable air volume (VAV) system, covering a total of 7,300 ft2.
The Minnesota Department of Transportation (MnDOT) maintains the state roads and highways in the Twin Cities Metro area from the Cedar Truck Station. Before the retrofit project, the building used outdated fluorescent lighting that over lit the building.
The University of Minnesota wanted to reduce energy costs in Jones Hall since the building had fallen behind in some of the University’s aggressive sustainability initiatives and needed new lighting and controls. The mixed-use building, one of many on campus, includes a combination of offices, classrooms, and public spaces, and is currently home to the University’s Admissions, Language Center, and College of Liberal Arts classrooms.
This is a case study for the Tinker Air Force Base. By replacing the existing lighting with LED fixtures, this project saved more than 60% energy compared to the existing technology. This is consistent with savings of converting either fluorescent or high-intensity discharge fixtures with either new LED fixtures or retrofit kits, which typically result in at least 45% savings. The lighting controls saved between 8-23% compared to the LED baseline. Because LEDs are very efficient, the new LED baseline uses less energy. As a result, the 20%+ savings does not result in sufficient savings for a reasonable payback. However, using lighting controls to control other building systems can make the lighting and control system more cost effective.
