In addition, Mary Ann Piette, Building Technology & Urban Systems division director and Cindy Regnier, FLEXLAB executive director, highlight FLEXLAB's unique capabilities in support of DOE priorities. From testing whole building retrofit systems to improving how buildings can store and share energy with other buildings on the grid, this short video includes expert commentary on FLEXLAB's capabilities.

Learn how FLEXLAB:

  • Enables integrated systems to work together to save time and money for building owners while improving the comfort of building occupants
  • Tests energy transfer and storage in the form of thermal mass, batteries and electric vehicle charging
  • Tests integration of buildings with the grid, saving energy and carbon emissions
"FLEXLAB can do controlled experiments ... and usually we can't do controlled experiments in a building where people are living and working."
