"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.

Understanding the needs of the industry and the customer to support the adoption of IoT technologies that can increase the uptake of energy saving products (e.g., LED lighting, sensors and controls) through energy savings opportunities (e.g., plug loads and HVAC) or valued non-energy benefits.
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.

Fact sheet that addresses when occupants interact with buildings and the data generated. The technology under consideration tests the promise of the Internet of Things (IoT) by using relatively inexpensive and easy-to-install wireless, lighting-fixture-based sensors that detect and record changes in occupancy, temperature, visible light, infrared radiation, and LED power consumption.
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.

GSA's GPG program commissioned LBNL to assess wreless ALC at two federal sites in Northern California. Results showed 54% normalized energy savings for GSA when fluorescent lamps with dimmable ballasts were retrofitted with wireless ALC, and 78% when the wireless ALC retrofit was coupled with LED fixtures. Wireless ALC integrated with LED fixtures is recommended for new construction and renovations, with simple payback between 3 and 6 years. It should also be considered for retrofits in facilities with minimal existing controls, high lighting energy usage, and high electricity costs.
