Tower Goes Dark for Longhorn Lights Out

Tower lighting is delayed for Earth Day

The University of Texas at Austin Energy and Water Conservation (EWC) Program is asking the campus community to turn off lights, computers, and other equipment when leaving campus buildings for the weekend on Friday, November 22, 2013.  Called Longhorn Lights Out, this voluntary initiative demonstrates how simple, individual actions can result in significant energy savings across campus.   During the September 2013 Longhorn Lights Out, the university saved almost 17,000 kWh of electricity--equivalent to turning off 1,900 compact fluorescent bulbs and removing the greenhouse gas emissions of 2.5 cars for one year.

In support of Longhorn Lights Out, the Tower will not be lit from sunset on Nov. 22 to dawn on Nov. 23.  The dark Tower will mark the third Longhorn Lights Out promotion and the first time the Tower has been dark for that initiative. (For safety reasons, the clock faces and aircraft warning lights on the Tower will be lit.)

On Friday, volunteers from the student chapters of Engineers for a Sustainable World and American Society of Heating, Air-conditioning and Refrigeration Engineers (ASHRAE) will assist with turning off lights and electronics, as they did in September.  The Division of Housing and Food Service will participate as well, as part of the division's sustainability efforts.  EWC is partnering with Texas Tower Public Relations in the College of Communications to promote the event.
