Window Film's Energy Savings Provide Quick Payback

Two, three-sided, 44-story towers clad in aluminum with a total 11,000 windows might pose a challenge for the HVAC system and a problem for the electric bill if placed nearly anywhere in the country. When the towers were constructed on a site in 1975 in sunny Los Angeles, however, they presented a particular challenge.
The Century Plaza Towers, landmark buildings in a town of landmarks, are home to 100-plus tenants, including high-profile film industry entertainers, agents and attorneys. They have suffered from temperature imbalances that made the space uncomfortable and added a significant energy cost burden to building manager, CB Richard Ellis. Cutting down on the solar heat load was critical to maintaining the plan to make the buildings more sustainable.
Renee Watkinson, vice president and director of the management firm, says her firm had taken a number of steps to enhance the towers’ sustainability, including reducing water use and lighting energy costs, and decided window film was the next step.
The firm considered a number of film manufacturers but turned to 3M for the project. Keeping in mind the historical importance of the building, the management team decided on Sun Control Window Film Neutral 35.
The project was completed in four months and utility bills began to drop immediately. Watkinson says the towers save 155,000 kWh per month and the payback was less than eight months.
Preston Commons is nestled in Park Cities, one of Dallas’ most coveted areas. It’s a three-building, Class A office complex with a total of 422,874 square feet, and it had a management problem.
Walls painted in graffiti, restrooms in serious disrepair, and roaches lurking in the cracks — hardly the way you’d imagine describing any school in America. Yet that’s what the students of Enterprise Middle School in Compton, Calif., faced every day.
The University of Utah — Salt Lake City has the goal of having at least one automated external defibrillator (AED) in each of the campus’ 300 buildings. Monitoring that many life safety devices, however, could have been a difficult task.
Chicago’s Museum of Science and Industry has a reputation for being a world-class museum with a focus on educating the public about inventions, scientific discoveries and other notable historic developments. It should be no surprise, then, that the museum would be open to exploring new ideas of its own to meet facility operational requirements.
