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
Research +
We are at the forefront of cutting-edge research that redefines building technology and explores all areas of urban systems.

We have been leaders for decades in developing energy-efficient windows, improving indoor air quality, coming up with new ideas to fix the nation's electricity grid, and so much more.

Berkeley Lab Organized an Urban Science Workshop

The Urban Systems Group at Berkeley Lab was official established on September 24, 2018, when a urban science workshop was conducted at Berkeley Lab. The workshop aims to integrate and expand urban science research through feedback on current activities and identification of strategic collaborations and opportunities. This multi-stakeholder workshop includes:

Technical report out on the three-year Laboratory Directed Research and Development project: Urban Integrated Systems
Comprehensive set of presentations on urban science activities at Berkeley Lab and University of California Berkeley (UCB) to collectively understand the current body of work in urban science
Multidisciplinary breakout brainstorming sessions and synthesis, to identify future R&D, funding, and collaboration opportunities between
Transport, buildings and distributed energy resources
International group and Building Technologies and Urban Systems
Energy Technologies Area, Computational Research Division, Earth and Environmental Sciences Area, and UCB
Research, academia, pilot and implementation projects
