1 2013 SHWEC Wisconsin Sustainability Internship Report Energy Reduction at Meriter Hospital – Dane Wudel Meriter Hospital Madison WI UW Solid & Hazardous Education Center

2 About Meriter  Primary facility covers 628,842 square feet  Annual electricity demand is roughly 24 million kWh  Lighting accounts for 28% of electricity usage; the largest single contributor to this demand

3 Lighting Survey  Document light fixtures throughout the hospital  Look for remaining A19 and T12 bulbs scattered throughout  Find energy efficient alternatives to current lighting schemes

4 Methods and Assumptions  Took apart one of each fixture on a floor and documented the number and location of fixtures per floor  Looked at one of each type (i.e. patient rooms) of room to avoid disruption to patients and staff  Looked for potential savings with a payback period of about 5 years or less  Strictly based on energy savings only

5 LED Lights  Minimal energy usage  Finally affordable  100% recyclable  Longer lifespan; less maintenance  No ballast needed  Designed for retrofits  Developed for most bulb types
