Advanced Plug Load Controls and Management in the Educational Environment
Mass deployment of advanced plug load management devices can cut energy and costs for community colleges
The project is complete and resulted in the installation of nearly more than 3,500 plug load controllers across multiple community colleges. The research team included the California Conservation Corps as the installers at 65 buildings across 13 community college campuses. The Embertec technology saved 44% of annual plug load energy savings compared to baseline plug load energy use. THe WattIQ technology saved 21% of annual plug load energy savings compared to baseline plug load energy use. The advanced plug load controllers have a simple payback of 8.3 years.
This project deploys APMD technology at approximately 3,500 computer workstations at several community colleges, and focuses on integrating the technology with facility operations to ensure that they meet the needs of the sites and staff. One of the devices is the Embertec Tier 2 Advanced Power Strip which controls an occupant's computer workstation by powering off when it detects no user presence by mouse movement or keyboard hits. The other device is the Ibis Intellisocket which controls large plug load end uses such as water coolers, TV displays, and large printers. Key features of the project include outreach and individual education programs to California Community College Districts, evaluation of sites for participation in the project, purchase and installation of APMDs at approved sites, measurement and verification (M&V) activities both pre- and post-APMD implementation at the selected demonstration sites. The goal is that the plug load controllers are reduce energy use by 20%.
The project gathered a wide range of data about the technology and its performance that was being incorporated into an outreach campaign to build awareness and accelerate the adoption of APMD technology with IOUs and vendors.
A conservative estimate of savings to the participating California Community College Districts is $850,000 per year in immediate and ongoing annual savings.
