BIPV News: Solaria Solar Windows Accepted By US GSA Green Proving Ground Program

February 5, 2016

After tests at Lawrence Berkeley National Laboratory’s (LBNL) FLEXLAB, Solaria BIPV (building integrated photovoltaics) solar windows have been accepted into the US GSA Green Proving Ground (GPG) program.

Solaria BIPV windows will be installed in a commercial pilot project in Kansas City, Missouri this year to demonstrate their viability as an aesthetic, energy generating solution. The test site slated for this pilot is a federal building in the city.


While demonstrating its BIPV technology in an occupied building, Solaria, the GSA, and LBNL will compile data on energy generation, thermal performance, daylighting, glare, and occupant comfort. This information will be compared with non-BIPV windows in the same building.


FLEXLAB is the first world testbed to evaluate the energy efficiency of major building systems, as an integrated system, under real-world conditions.

According to FLEXLAB, stakeholders can evaluate energy efficient building technologies individually or as integrated systems in advance of building projects or retrofits, in order to:

  • Optimize integrated systems to maximize energy savings
  • Ensure occupant comfort and user-friendliness
  • Verify cost-benefit numbers
  • Train building operators
  • Build confidence in new technologies

“By measuring a building’s energy use under real-world conditions and on a significant scale, FLEXLAB provides real-time assessment of building energy use. FLEXLAB offers a way to test-drive energy efficiency systems, identify problems, and make changes before breaking ground. FLEXLAB unleashes the real potential of energy efficiency in buildings.

“In addition to the factors above, it includes evaluation of the design-build process and economics,” the company
