Energy Management System Saves University $400,000 a Year
Weber State University in Ogden, Utah, is committed to becoming a carbon-neutral campus by 2050. But ad-hoc energy efficiency projects have not been enough to meet energy reduction targets, so the university purchased a sub-metering systems for its entire portfolio of energy systems, using Lucid’s BuildingOS to make performance data instantly accessible. Access to real-time data at the sub-meter level allows the university to pinpoint which buildings and systems are consuming the most energy, and when.
Weber State connected its existing building automation system to Lucid’s Tridium JACE and Obvius data-loggers, which allowed the university to monitor multiple points of data in each building.
BuildingOS has benefitted the university’s energy strategy in a number of ways. Access to meter data has allowed Weber State to identify and prioritize retrofit projects. The product’s Building Dashboard publicly displays real-time energy data on the university’s website as well as on several touch-screen kiosks across campus, allowing students to engage in energy savings competitions using the data to make behavioral decisions.
Energy output data allows the facilities team to properly size back-up generators, and electricians use the data to conduct fault leak detection. The teams also set up notifications to alert them any time something unusual is happening.
Energy data is also accessible to other entities on campus. For example, landscapers can track data from their irrigation projects, and project managers can adjust the sizing of equipment in new building construction. On the educational side, professors and students use the data to conduct research on energy efficiency and LEED policies.
Throughout 2013, the university has recovered $1.4 million in energy savings through an array of projects including building management improvements, lighting retrofits and infrastructure changes. Optimizing HVAC system scheduling across campus accounted for about $400,000 in energy savings.
Ultimately, savings from operational efficiency improvements through BuildingOS were responsible for 30 percent of overall energy savings on the campus. Operational savings helped Weber State save 9 percent of its total energy budget in 2013.
Last year, the university replaced high-intensity discharge (HID) lighting at its Dee Events Center with GE’s Albeo LED High Bay lighting with the target of saving $40,000 annually.
