Hidden Energy Savings: Retrocommissioning and Relamping

Leave a comment

The University of Connecticut is in the midst of an extensive retrocommissioning and relamping project as part of the energy efficiency priority of UConn’s Climate Action Plan.

Retrocommissioning (RCx) is the process by which the systems and equipment of existing buildings are tested and modified so that the building is running optimally and efficiently. UConn has broken up its retrocommissioning projects into three phases over four years starting in 2011. As of Summer 2013, the university had completed retrocommissioning projects for 19 buildings. These projects, along with other UConn energy efficiency measures, should save over 20,500,000 kWh of energy over the course of a year. The largest savings are coming from the Homer Babbidge Library, the Pharmacy Building, and the Student Union.

Of course, energy isn’t free, so in addition to saving energy, retrocommissioning should save the university about 2 million dollars a year.  Phase 3 of the retrocommissioning projects is set to begin in Fall 2013 and continue through 2014. Some of the buildings that will be included in Phase 3 are the South Campus Dorms, the Music Building, the Dodd Center, Von der Mehden Recital Hall, and the School of Fine Arts.

Relamping is another ongoing energy efficiency project at the University of Connecticut. Relamping works to upgrade the lighting systems of a building by replacing inefficient bulbs with more efficient varieties. These upgrades will increase energy efficiency, decrease overall energy use, and reduce greenhouse gas emissions moving UConn forward with its sustainability goals. As of the end of the summer, 80 relamping projects had been completed at UConn. As a result of this effort the university is projected to save 4,065,870 Kwh of energy and $398,013.06 per year. It is incredible that a seemingly small change, like light bulbs, can amount to such large savings.

Both retrocommissioning and relamping are excellent examples of UConn’s proactive and effective push for sustainability. Although most people don’t see the changes from retrocommissioning and relamping, they are one of our most effective energy-saving tools! The average reduction in energy from a retrocommissioning project is 16 percent and the implementation of new lighting systems can reduce lighting energy demand (29% of a buildings total energy demand) by 59%. UConn recognizes the value of both relamping and retrocommissioning and has made them priorities in the Climate Action Plan.
