Recommended energy saving strategies (check all that apply): __X__ leave lighting alone, it’s already efficient ____ replace with more efficient lamps & ballasts ____ delamp to reduce over-lighting __X__add controls to reduce operating hours Part D - F do not to our school. We have two lamps per fixture and are using lamps. As mentioned above all rooms in our school do need occupancy sensors. Maintenance has a plan of installing T-5 lamps in the main part of the Gym to help save on the energy bill. This will hopefully take place next school year.
