Luther to begin room-by-room energy and lighting study

Recipient of a 2012 Second Nature Climate Leadership Award. One of eight colleges across the country to receive an "A" on the 2011 College Sustainability Report Card.

Luther is starting a campus-wide, room-by-room energy study that will focus on modifying lighting levels and improving HVAC controls and performance.  Luther College sustainability staff and work-study students are collaborating on this unique project with Michaels Energy, an engineering firm in La Crosse, Wisconsin. Potential opportunities for energy efficiency associated with this study include:

  • Reducing over-lighting by replacing or retrofitting fixtures, lamps and/or ballasts.
  • Increasing the opportunity for day-lighting or reduced artificial lighting when reduced levels meet occupant needs.
  • Modifying switching and wiring to allow multiple lighting levels or zoned switching based on daylight availability.
  • Increasing the use of day-lighting by using daylight sensors and controls.
  • Eliminating lighting usage when spaces are unoccupied via occupancy sensors.
  • Reducing HVAC energy use when spaces are unoccupied.
  • Reducing HVAC energy use in variable-occupancy spaces through the use of carbon dioxide sensors. 

The goal is to complete the study by June 2014.
