The effectiveness of light switch reminders in reducing light usage

A study done by Institute for Research in Construction, National Research Council of Canada, Ottawa, Ontario K1A 0R6, Canada, Department of Psychology, Carleton University, Ottawa and The Rose Technology Group, Toronto

Summary: A carefully controlled field study has shown that reminder stickers attached
to light switch plates reduce lighting energy consumption in private offices. The
magnitude of the energy savings is large enough for the switch stickers to be cost
effective in 10 weeks or less. A questionnaire administered at the end of the study
showed that people were generally receptive to the switch stickers as reminders for
saving energy.
