  • About Us +

    Researchers in the Building Technology & Urban Systems Division (BTUS) at Lawrence Berkeley National Laboratory develop data and technologies that increase energy efficiency and improve the health, safety and comfort of building occupants, in the United States and worldwide.

    We work closely with industry partners, academics and government officials to achieve these goals, and share our research widely
