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.

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

Denver Water is recognized for implementing Integrated Controls for HVAC and Lighting Systems.
