"The decision guides found in this resource were created to help building owners find the right control strategy for PPLs in their buildings. The guides are developed for different building types and outline the costs, potential savings, complexities, and user friendliness of various control strategies and their applications to each building type. The guides also aim to help building owners determine whether a control is appropriate for particular project applications such as staged retrofit projects, whole-building retrofits, new construction projects, and projects that involve tenants and landlords. Lastly, the guides provide links to additional resources that can further help building owners assess and reduce the energy use that is associated with PPLs, find rebates for PPL control measures, and procure the right control types for their building equipment."
This fact sheet covers the potential for deeper energy savings and occupant comfort through the integration of lighting controls and automated shading. Research conducted by Lawrence Berkeley National Laboratory found an annual energy savings up to 30% in controlled zones compared to a baseline lighting system. Furthermore, occupant comfort (i.e., non-energy benefit) potential was identified, as the system maintained an acceptable level of Daylight Glare Probability at almost all times and maintained illuminance at the workplane at all times.

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.
Success with lighting controls depends on establishing clearly defined objectives and taking a disciplined approach to design and implementation. This practical guide describes four common use cases for lighting controls and outlines the implementation process, from planning through maintenance.

Connected lighting systems provide a platform where integrated control of lighting and other systems can enhance building performance. With detailed information, coordinated systems can deliver lower operating costs and improved return on capital, as well as enhanced occupant wellbeing and productivity.

COVID-related absenteeism has cost US employers an average of $1 Billion per week since the pandemic began. Concern about the spread of infections in the workplace has driven many building operators to increase outside air ventilation at a significantly increased energy cost. Recent research from Pacific Northwest National Laboratory and others finds that well-designed germicidal UV systems can be more effective and far more energy efficient than increasing ventilation to prevent the spread of airborne illness. The Better Buildings Lighting Systems Technology Research Team shared insights on germicidal ultraviolet radiation and its impact on both energy use and airborne pathogens.

Indoor farming, or controlled environment agriculture (CEA), is an energy and resource intensive process but has the potential to produce high value crops at maximum productivity and resource efficiency when ideal growing conditions are met. To meet ideal growing conditions, the facility’s horticultural systems, like lighting, HVAC, and humidity must be finely tuned and controlled. Integrating these systems can yield synergistic energy savings and, just like commercial facilities, the lighting system and controls can serve as a solid foundation for integration through data collection via sensors and providing a network interface. Watch to learn from the Better Buildings Lighting Systems Technology Research Team and two Integrated Lighting Campaign Recognized partners, University of Vermont and Vertical Harvest Farms, as they share their success stories in integrating their lighting with horticultural controls.

Healthcare Campus Recognized for Innovative Use of Lighting Sensors and Controls
The Minnesota Department of Transportation (MnDOT) has more than 1,075 buildings with 137 truck station campuses across the state. MnDOT’s Cedar Avenue truck station, located in Richfield, Minnesota, provides critical roadway snow removal support within the Minneapolis metro area. It includes administrative offices, a training room, and a large breakroom, along with truck maintenance and service facilities.
The focus of this case study is to highlight the strategies used at Cedar Avenue truck station for integrating plug load and lighting systems. An integrated controls pilot project with retrofit installation was conducted from October 2019 to April 2020 and has been recognized by the Integrated Lighting Campaign in the following categories:
- Integrated Controls for Plug Loads & Lighting Systems
- Integrated Controls for HVAC & Lighting Systems
With a large portfolio of buildings, college campuses present a unique opportunity to adopt connected lighting systems for the benefit of the students, professors, administrative staff, and the public. And that’s just what both California State University, Dominguez Hills (Cal State Dominguez Hills) and the University of Minnesota did. Cal State Dominguez Hills wanted to decrease energy costs at James L. Welch Hall (Cal State), a four-story building housing multiple functions, including administrative and admission offices, classrooms, tech support, server rooms, and a police station. The University of Minnesota had similar goals for Jones Hall (UMN), one of their mixed-use buildings on campus with a combination of offices, classrooms, and public space.
Denver Water is recognized for implementing Integrated Controls for HVAC and Lighting Systems.
IMEG, a national engineering and design consulting firm, put innovation to the test when designing their new Chicago office. In collaboration with Pacific Northwest National Laboratory (PNNL), IMEG implemented several emerging lighting techniques as part of a study to better understand the physiological and psychological impacts on occupant comfort, well-being, and energy savings.
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.
