LED Lighting Retrofit for the C.V. Starr-East Asian Library
Project Lead: Anthony Bum Kim
Sponsor: Environmental Committee/Graduate Assembly, Jeffrey Kessel – PE/Energy Office/Physical Plant, Frank Carter – Electrician/Energy Office/Physical Plant
TGIF Mini-Grant: $600
Project Theme: Energy Conservation & Efficiency
2013 Application Submission
Status: In Progress
Project Description: As part of an energy-efficient equipment upgrade strategy in the C.V. Starr – East Asian Library, the project leader will replace incandescent bulbs with LED bulbs.
Replace 39 low-efficacy incandescent bulbs with high-efficacy LED ones in the C.V. Starr – East Asian Library.
The modeled life-cycle costing hopes to generate a payback in 126 days and a 10 yr. positive cash flow position of +$51,492.74.
Products purchased and placed on site, waiting for EO Electrician to schedule swap/installation.
An LED specification change was made for a couple reasons.
Since the proposal of this project was approved, CREE has developed and released a new LED spec. bulb certified by the California Energy Commission; this bulb was designed with a higher color rendition index (CRI) to support the qualitative aspects of lighting.
As part of a market campaign this spec. bulb was put on sale from $19.99 to $9.99. The combination of lower initial cost and increased wattage from 9.5 watts to 13.5 wattage has slightly changed the quantitative metrics.
Estimated payback changed from: 126 days to 119 days
10 year positive cashflow position changed from: $51,493.74 to $51,274.77
Calculated Yearly energy savings (kwh) changed from: 11,950.19 to 11,356.39
Calculated yearly GHG reductions (kg Co2e) changed from: 2,473.69 to 2,350.77
