Warner Bros. invests in energy conservation measures, including the installation of efficient lighting, updated HVAC equipment and automated control systems such as timers, motion sensors and wireless thermostats. Over the years, these projects have combined to conserve over 12 million kilowatts annually, the equivalent of providing electricity to over 1,000 homes.
Our Studio is also participating in an enterprise-wide energy initiative lead by the Time Warner Global Real Estate Group (TWGRE) to manage utility usage across our real estate portfolio.
Warner Bros. is installing new “house lights” equipped with energy-saving technologies on our stages. These induction lights are 240 watts compared to conventional 400 watt metal halide lights typically used in high bay applications. Also, these innovative lights turn on at only 40 watts to provide instant low level light. Then, each light has a motion sensor that, when activated, increases to full light levels. So, only stage areas in use are fully lit. It is estimated that this technology will save about 35,000 kwh of electricity per stage, per year.
The large doors at the front of each stage are referred to as “elephant doors.” These sliding doors are equipped with sensors that automatically shut of air conditioning systems when the doors are opened beyond a few feet. This reduces air conditioning demands and conserves energy by preventing cool air from escaping. It also keeps the stages more comfortable for our production crews and audiences.
RENEWABLE ENERGY – SOLAR
In addition to energy conservation, Warner Bros. invests in renewable energy projects.
In 2002, Warner Bros. piloted a small solar project on the roof of the Warner Bros. Photo Lab. Following the success of this pilot project, a 72-kilowatt solar power system was constructed on the roof of the Studio’s Mill Building in 2006. This system was the first large-scale solar power project in the entertainment industry. In 2008 this system was expanded to more than 500 kilowatts, comprised of 2,722 solar panels spanning 79,000 square feet of roof space.
Additionally, in 2009 a 100-kilowatt system was installed on Stage 23, bringing the Studio’s total solar energy portfolio to over 600 kilowatts. These projects have an expected 30-year lifespan and generate 1.15 million kilowatts of clean energy annually, enough to power over 150 average homes.
