ST. CHARLES MEDICAL CENTER A Green Lights / ENERGY STAR Case Study (ABSTRACT)

This case study abstract describes the process by which Mike Severns, Director of Facility Services at the non-profit St. Charles Medical Center, evaluated energy conservation measures (ECMs) through the EPA's Green Lights and ENERGY STAR Buildings programs. It highlights the Green Lights Program, launched in 1991 to reduce air pollution and electricity costs by promoting energy-efficient lighting, noting that lighting accounts for 20-25% of electricity sold in the U.S.

• The United States Environmental Protection Agency (EPA) established the Green Lights Program in 1991 as a voluntary, non-regulatory initiative to reduce air pollution by encouraging the adoption of energy-efficient lighting. Participants committed to evaluating the replacement of existing office lighting with more efficient fixtures and bulbs, implementing retrofits if they proved profitable. The program aimed to lower electricity costs and reduce emissions of heavy metals, nitrogen oxide, sulfur dioxide, and carbon dioxide.
• Mike Severns, the Director of Facility Services for the non-profit St. Charles Medical Center, was tasked with determining the viability of specific retrofitting projects as part of the hospital's energy conservation program. His decision-making process involved evaluating energy conservation measures (ECMs) based on intangible factors and strict financial analysis to decide if participation in the ENERGY STAR Buildings and Green Lights programs was worthwhile.
• Lighting is identified as a significant energy consumer, accounting for 20-25% of all electricity sold within the United States.
