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.
