The Upper Arlington Public Library anticipates increasing visibility and saving money on utility bills by upgrading light fixtures at the main library at 2800 Tremont Road.

The Upper Arlington Public Library anticipates increasing visibility and saving money on utility bills by upgrading light fixtures at the main library at 2800 Tremont Road.

Library officials and board of trustees members discussed the pending upgrades at the board's Dec. 15 monthly meeting at the main branch.

John Forgos, a general contractor who handles repair and maintenance issues at UAPL's three branches, said light levels throughout the main library are below current standards.

Industry standards for libraries dictate that light-detection levels should register at meter readings of 30 to 40 foot-candles per square foot, Forgos said.

Light levels are particularly low in the main branch's adult section, coming in at readings of just 1 to 12 foot-candles per square foot.

"Only the atrium meets or exceeds requirements," he said.

Replacing 160 light fixtures throughout the main branch in addition to 429 that have already been replaced would also cut energy consumption by 40 percent, Forgos said.

American Electric Power's guidelines indicate that libraries should burn 1.3 watts of electricity per square foot, while the main branch burns 2.5 watts per square foot. Forgos estimates replacing light fixtures throughout the main branch would reduce consumption to 1.5 watts per square foot.

The project includes the installation of sensors that would lower lighting levels in the atrium on sunny days when natural light is sufficient to illuminate the area, Forgos said.

According to estimates, the lighting upgrades will cost $213,000, which includes a $24,000 fee for Forgos to manage the project, said library director Ann Moore.

The board voted to authorize Forgos to engage a minimum of three architectural/engineering firms to prepare design bids for replacing fixtures in the atrium and adult sections of the main branch. Work is tentatively scheduled to begin in April.
