Shading and Lighting Retrofits Slash Energy Use in New York “Living Lab” Office Demonstration

By using advanced lighting and automated shades, Berkeley Lab scientists found that occupants on one floor of a high-rise office building in New York City were able to reduce lighting energy usage by nearly 80 percent in some areas. The dramatic results emerged at a “living laboratory” set up to test four sets of technologies on one 40,000 square-foot floor of a building.

‘Expert in a suitcase’ Cuts Power Bills 10% in Small Commercial Buildings

The knowledge and expertise of a seasoned energy efficiency professional has been packed into a high-tech suitcase. The Sensor Suitcase is a portable case that contains easy-to-use sensors and other equipment that make it possible for anyone to identify energy-saving opportunities in small commercial buildings.

Art Rosenfeld, California’s Godfather of Energy Efficiency, Dies at 90

Art Rosenfeld, a Lawrence Berkeley National Laboratory Distinguished Scientist Emeritus who is also known as California’s “godfather” of energy efficiency and who has been credited with being personally responsible for billions of dollars in energy savings, died Friday at his home in Berkeley, California. He was 90.

The Rosenfeld Question: Art Rosenfeld’s Tang Lecture Given by Ashok Gadgil

How do you speak on behalf of a living legend like Berkeley Lab’s Art Rosenfeld, a particle physicist who attained international recognition as the “godfather of energy efficiency?” That was the challenge faced by Ashok Gadgil on September 25 in Taipei City, Taiwan.

Nine Innovative Approaches That Utilities are Using to Plan for Increased Rooftop Solar

Berkeley Lab-led report offers a comparative analysis of roughly 30 recent utility integrated resource plans or other generation planning studies, transmission planning studies, and distribution system plans.

Berkeley Lab Awarded DOE Grants for Greener Buildings

Berkeley Lab has been awarded more than $4 million by the Department of Energy (DOE) to undertake three projects aimed at improving the energy efficiency of buildings, which account for more than 40 percent of the country’s energy consumption and greenhouse gas emissions.

5 Nanoscience Research Projects That Could Deliver Big Results

Berkeley Lab researchers are using the science of the very small to help solve big challenges. That’s because, at the nanoscale—the scale of molecules and proteins—new and exciting properties emerge that can possibly be put to use. Here are five projects, now underway and recently highlighted in the News Center, which promise big results from the

Data Centers Continue to Proliferate While Their Energy Use Plateaus

As the number of data centers continues to increase in the United States, the good news is that they are becoming much more energy efficient. A new report from the Lawrence Berkeley National Laboratory has found that electricity consumption by data centers nationwide, after rising rapidly for more than a decade, started to plateau in 2010 and has remained steady since, at just under 2 percent of total U.S. electricity consumption.

Roof Racks a Drag on Fuel Economy

As you get ready to hit the road this summer, with the kids loaded inside and the bikes strapped to the roof of your car, you may want to stop and consider that the roof rack on your car may be costing you as much as 25 percent more in gas.

Berkeley Lab Projects Could Save California More Than $2 Billion Annually in Energy Costs

Plug loads, or devices that plug into the wall, are responsible for at least 25 percent of electricity use in California buildings. And not only is that percentage growing, it’s a hard number to manage.
