LIGHTSOUT HOUSTON - BEFORE


LIGHTSOUT HOUSTON - AFTER


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.


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.


THE SIGN COMPETITION

A key strategy that spread the word

Over 150 signs distributed in 100 buildings

Signs posted on websites, elevator lobbies, and Captivate screens


RESULTS…

• 90 million square feet committed to maintaining a sustained reduction in the use of non-essential electricity.

• This equates to 350,000 kilowatt hours or $35,000 saved over one weekend.

• Annualized, this would be 42,800,000 kilowatt hours or $4.3 million – enough electricity to power 3,140 average Texas homes for a year.

• At a time when companies are looking for ways to save money, conservation may be the simplest solution yet.
