A major efficiency project underway at Norlin Library is updating the building in terms of sustainability, comfort and operational savings. As part of a broader initiative spanning 18 buildings across the university, Norlin’s upgrades are among the most impactful.

The project, which began in May 2025 and is expected to continue into summer 2026, includes converting approximately 4,500 light fixtures, representing 10,000 bulbs, to energy-efficient LEDs.

A brighter, safer and smarter Norlin

More than half of Norlin’s lamps have been converted with the goal to not just improve efficiency, but also the experience of studying and working in the spaces.

“We’ve heard from staff in one of the updated spaces that it feels like coming out of the Dark Ages,” said Claire Hoag, director of the Libraries Engaged Spaces Team. “The difference in brightness and clarity is dramatic.”

The new lighting features a 3500 Kelvin color temperature, a warm illumination that’s noticeably different from the cooler tones of the previous fixtures. Occupancy sensors and programmable controls will allow lights to automatically turn off when spaces are unoccupied and back on when needed. By the end of the project, there will be programming to automate lighting schedules, turning off lights at night and back on in the morning. Importantly, night lights will remain lit in stairwells and exit pathways to ensure safety during power outages or emergencies. Up to 95% of the offices in Norlin will also have the ability to dim their lights.

A highlight will be upgrading the existing high bay lights over the Ask a Librarian desk with new light fixtures. These updates are expected to:

• Significantly reduce energy consumption
• Transform the spatial experience of the room
• liminate the white noise currently produced by the existing lighting

“This is a big step toward more comfortable and efficient spaces,” said Christopher Yago, head of Libraries building management and Norlin Building Proctor. “We’re excited to see how these changes benefit both the built environment and the people who use these spaces every day.”
