Lighting Systems

This case study 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 (LBNL) found annual energy savings of up to 30%.

This case study by LBNL explains the energy and cost savings potential of task/ambient lighting systems when integrated with plug load occupancy controls. 

This case study by LBNL explains the energy and cost savings potential of workstation-specific lighting with daylight dimming controls. 

The James Forrestal Building in Washington, D.C. – headquarters for the U.S. Department of Energy – implemented a lighting upgrade project through an energy savings performance contract (ESPC), curbing lighting energy use by about 50% and saving nearly $258,000 per year.

This case study covers how CentraCare upgraded their Becker, MN site by utilizing a packaged solution for a lighting retrofit, including site survey, design, system selection, and financial assistance with materials and labor.

This case study highlights how Hennepin County, MN partnered with Slipstream to integrate light-emitting diode (LED) lighting with luminaire-level lighting controls (LLLCs), automatic receptacle (plug load) controls, and HVAC controls on one floor of a multistory building, 

This case study details the field validation of a lighting retrofit with HVAC Integration and Plug Load Controls at the Minnesota Department of Transportation (MnDOT) building. 

This case study details the field validation of a lighting retrofit with HVAC integration and plug load controls at City of St. Paul Streets Maintenance Division building.

This case study details the field validation of a lighting retrofit with HVAC integration and plug load controls at the University of Minnesota Jones Hall building. 

This fact sheet provides federal facility managers with an overview of the energy savings potential of wireless lighting occupancy sensors for room types, cost, installation of wireless sensors, light source, and codes and standards.

This fact sheet summarizes key components of the Better Buildings High Efficiency Troffer Lighting Specification and how to apply it to save energy and money by upgrading to high- efficiency LED technology.

This fact sheet provides technical information on initial costs, operating costs, current light levels, and dimming requirements to consider when deciding on an LED upgrade for a fluorescent troffer system.

Retrofitting fluorescent troffers with LED sources can lead to project-level savings between 20% and 60%. To achieve these savings while maintaining high-quality lighting, facility managers need to consider a number of factors — this fact sheet provides retrofitting guidance, including the LED and control options available, the benefits and disadvantages of each option, and agency-specific requirements.

Interior Lighting Campaign (ILC) participants have replaced more than 3.5 million lighting systems saving roughly 800 million kWh of electricity annually and $85 million in energy costs. This report summarizes 4 years of results and lessons learned after reviewing more than 3,500 retrofit projects submitted through the ILC.

This report from PNNL summarizes research into industry and customer needs around the adoption of IoT technologies and lays out the barriers and best practices that need to be addressed to move forward.

The full report and report summary focuses on an evaluation of a set of advanced lighting control systems and their potential application to U.S. General Services Administration (GSA) facilities.

The latest high-efficiency alternatives with energy-saving controls—including light-emitting diode (LED), induction, and fluorescent technology options—can save building owners over 40% on their parking lot lighting bills.

This toolkit collects resources from the Interior Lighting Campaign to help facility owners and managers take advantage of savings opportunities from high-efficiency interior lighting solutions.

Researchers from the Pacific Northwest National Laboratory evaluated five different LED systems with ALC at a test-bed site in Fort Worth, Texas, and provided an analysis of the added savings and costs of the controls as well as guidance on where ALC with LED can be best deployed.

This interactive 2020 Summit workshop provided an in-depth look at how leading-edge lighting systems are capable of communicating with other building systems to enable additional energy-saving opportunities while collecting valuable insights about a business’s operations.
