Description
The Rodgers Memorial Library in Hudson is a beautiful community asset for the town of Hudson, NH and the surrounding area. The Board of Directors was committed to improving the carbon footprint of the facility, and operating the building in a more energy lean manner.
Investing in energy savings measures which would yield substantial reductions in a cost-effective, verifiable manner was important. The interior lighting consisted of a variety of decorative and architectural designs, and it was desired to retain the aesthetics of the public and employee spaces. This was Stage I of the energy savings.
HVAC – air conditioning in particular – was shown by the analysis to be an additional area which could benefit from improved operations to reduce power use.
Savings Summary
actual projected

Objectives
- Replace all lighting with far more efficient LED technology, with dimmable/controllable capability
- Retain the the many and varied fixture types – hanging round, recessed, linear uplights, panel troffers, etc
- Reduce energy costs, and associated resource and carbon use profile
- Cut operating costs overall
- Identify possible future measures to be taken towards continued reductions
Technologies Deployed
- LED Lighting – reductions in power draw of 55% – 65%. Stage I.
- 13 Distinct LED Form Factors – exterior w/photosensor control. Stage I.
- Refrigerant lubrication – improving heat transfer and compressor operation. Stage II.
“There is no better way to save money on your electricity bill than to upgrade your lighting from traditional fluorescent bulbs to high efficiency LED lighting! We are saving between 18% and 31% each month.”
