Denver's National Renewable Energy Laboratory installs Heat Shield window film to help reduce their carbon footprint.

 Heat Shield window film was installed at NREL (National Renewable Energy Laboratory Golden, CO). NREL’s data center was experiencing unacceptable and potentially very costly heat related failures. The cause was Colorado’s intense sunshine. Heat Shield competed against 3M window films Prestige 70 film and was awarded this contract due to their superior products and local commercial experience. Data center manager Kevin Donavon said, “Since the application of Heat Shield on our southern windows we have not had one heat related failure to our servers”.
