Columbia University Wins NRG Bronze Award for Excellence in Energy
Facilities and Operations team recognized for driving emissions reductions and cost savings.
The Facilities and Operations Engineering and Energy Management team has been honored with a Bronze Award in the Energy Efficiency category at NRG Energy’s 6th Annual Excellence in Energy Awards – recognition of the University’s commitment to sustainable operations.
NRG’s Excellence in Energy Awards recognizes businesses demonstrating leadership in energy innovation, operational efficiency, and sustainability. This year’s awards salute organizations “not only meeting today’s energy challenges but also helping to shape a cleaner, smarter energy future.”
Leading Campus-Wide Energy Innovation
For more than a decade, the Engineering and Energy Management team within Facilities and Operations has maintained and optimized critical building systems — mechanical, electrical, plumbing, and fire safety — across Columbia’s campuses. The team continuously refines these systems through data-driven strategies, regular audits, and advanced energy tracking. Working cross-functionally with Columbia’s Office of Sustainability, their efforts extend beyond maintenance to actively planning and implementing sustainability-oriented projects.
The Energy Management team monitors 88 buildings across Columbia’s campus, totaling approximately 9.5 million square feet using sophisticated infrastructure that tracks energy use, cost, and emissions in real time via sub-metering, Supervisory Control and Data Acquisition (SCADA), and Building Management Systems (BMS).
Measurable Impact
The award recognizes several impactful initiatives that collectively save thousands of metric tons of carbon emissions annually:
- Steam System Insulation Upgrades: Comprehensive insulation repair across 39 buildings on Morningside campus identified and addressed missing or damaged steam jacket insulation. The project harnesses QR-coded insulation jackets to ease maintenance and reduce energy loss. Result: ~19,000 MMBtu/year saved and ~1,009 tCO₂e/year avoided.
- Sequence-of-Operations Optimization for Lab Air Handling: In the Northwest Corner Building, four large air-handling units were reprogrammed to act in unison, leveraging shared ductwork and a water-loop heat-recovery system tailored for lab safety. Similar work is underway in Fairchild, Engineering Terrace, and Computer Science buildings. Result: ~21,000 MMBtu/year saved, ~1,085 tCO₂e/year avoided.
- Control System Modernization: On the Manhattanville campus, the team piloted a project to replace proprietary air-handling unit controls on the Kravis and Geffen buildings with adjustable, in-house systems. Pilot projected savings: ~1,030 MMBtu/year, ~69 tCO₂e/year.
- Lighting Upgrades: Campus-wide lighting retrofits and control system upgrades have been implemented in over 2.1 million square feet, delivering energy savings of 2,563 MWh/year and reducing emissions by 939 tCO₂e/year to date.
- Demand Response Participation: In 2024, Columbia responded to 14 demand-response events and earned over $1 million in cost savings.
- Real-Time Energy Monitoring Platform: The team is building an integrated data platform that aggregates sub-meter data, SCADA/BMS data, and utility meter data to monitor energy consumption, cost, and emissions. This enables validation of energy projects and preparation for future carbon-driven operational strategies.
Several of these projects have been financed by Columbia’s Green Revolving Fund, a mechanism that re-invests the cost-savings from completed energy initiatives into future efficiency work, accelerating the University’s progress toward its net-zero by 2050 goal.
Reaction and Significance
“We are deeply honored to receive NRG’s Bronze Excellence in Energy Award,” said David Greenberg, Executive Vice President for Facilities and Operations at Columbia University. “This recognition validates the hard work of our engineers and operations staff and reflects our shared commitment to a more sustainable and efficient campus. Our cutting-edge systems and projects not only generate cost and energy savings — they drive real emissions reductions. We see this as a stepping stone, not a finish line.”
Robert J. Gaudette, Executive Vice President and President of NRG Business & Wholesale Operations, commented, “Over the past six years, we have seen incredible dedication to progress in energy innovation and resilience. These awards are about honoring that commitment and looking ahead to the possibilities still to come.”
