3D-printed polylactic acid-microencapsulated phase change material composites for building thermal management

Abstract The integration of phase change materials (PCM) into architectural elements is an emerging strategy to enhance thermal energy storage in modern buildings. This research examines 3D-printed polylactic acid structures incorporated with microencapsulated PCM, targeting a more efficient thermoregulation in…

Bright Lights + Big City = Millions of Dollars in Savings

The city of Chicago has replaced 210,000 street lights with state-of-the-art LEDs through its energy-efficient street lighting initiative. Pacific Northwest National Laboratory lent its technical expertise to the team – led by the Chicago Department of Transportation – to help identify the best lighting technology and field validation approaches to Chicago’s outdoor lighting modernization effort.
