4. WHY LIGHTSOUT HOUSTON? Housekeeping typically turns off building lights at 10 PM. Office workers leaving after housekeeping at 10:30 PM would leave lights on all weekend. By Sunday night most buildings remain 25% to 75% lit. Security/housekeeping will go back up to turn off lights after tenants have left the building. Need to change behavior. LightsOutHouston.com

5. HOW DOES IT WORK? LightsOut Houston is part of a long-term strategy for Houston to become THE Energy Conservation Capital. The goal is to establish a sustained reduction in the use of non-essential electricity in commercial buildings. This program involves obtaining a pledge by those committed to implementing energy efficiency measures and operating procedures that will lead to a sustainable reduction in electricity consumption.
