Abstract
Nayyar, Ridhima A. Assessing the Potential for Energy and Economic Savings from Lighting Retrofits at Illick Hall. Word processed and bound thesis, 164 pages, 44 tables, 34 figures, 2010
A majority of the lights used within Illick Hall at SUNY-ESF were last upgraded ~15 years ago. I performed an energy and economic analysis of various lighting retrofit scenarios within Illick Hall to test if any of the proposed lighting retrofits yield lighting energy savings of greater than 25% over the existing lighting system. The lighting retrofit scenarios involved replacing the existing T8s with energy efficient T8s, T5s and LEDs, both with and without occupancy sensors. I also hypothesized that the lighting retrofits will yield a monetary payback of less than five years. I calculated the annual electricity consumed by lighting and various costs of implementing lighting retrofits, across the whole of Illick Hall and various room categories.
Only two out of the seven proposed lighting retrofit scenarios yield lighting energy savings of more than 25% along with a monetary payback of less than five years for the whole of Illick Hall. Corridors, laboratories and offices occupy ~75% of Illick Hall's floor space. Energy savings of greater than 25% and a payback of less than five years can be achieved for four out of the seven proposed lighting retrofit scenarios within corridors. None of the retrofit scenarios for laboratories and offices result in energy savings of greater than 25% coupled with a payback of less than five years.
Key Words: energy efficiency, LED, lighting systems, occupancy-sensors, payback-period, lighting retrofits, T8, T5,
