The Building Technology and Urban Systems Department at LBNL has an extensive array of testing capabilities for material characterization and performance monitoring of a wide range of building technologies.
Our Lighting Systems Test Facilities aid research that improves the energy efficiency of lighting systems.
- Integrating Sphere: Provides fast and accurate measurement of the total light output of a lamp.
Windows & Envelope Materials
- Advanced Windows Test Facility: Tests new window technologies for energy savings and occupant comfort. This multi-room laboratory simulates real-world office spaces and measures the performance of commercially-available and prototype window systems such as electrochromic windows and automatically controlled shutters and blinds.
The Glazing Optics Laboratory has a complete set of instruments designed to characterize the detailed radiometric and optical properties of window glazing and shading materials, including:
- Photo-Goniometer: Measures light transmission and reflection of light-emitting, light-scattering, and light-redirecting materials.
- Pelletron: An electrostatic ion accelerator made for ion beam analysis of materials.
Thermography and Heat Transfer
Thin Film & Deposition Systems
- Coating Lab: Contains chambers for growing thin film window coatings.
Additional LBNL Facilities
In addition to the above Department-specific facilities, LBNL is home to a number of world-class facilities, including:
- Advanced Light Source (ALS): A particle accelerator that generates bright beams of x-rays for scientific research in biology, chemistry, physics, materials, energy, and environmental science. This national user facility attracts more than 2000 researchers and students annually from around the world.
