A Clear View of Window Energy Savings

May 06, 2019

A leading energy efficiency group recently highlighted research from Lawrence Berkeley National Lab (Berkeley Lab) as part of a blog post about new in-store labels for window coverings. The labels for attachments such as blinds and shades are informed by a product rating and certification program developed via extensive modeling and research at Berkeley Lab. The text from the American Council for an Energy-Efficient Economy (ACEEE) follows:

Super Window Could Save Billions

June 05, 2018

About $20 billion worth of energy leaks out of windows in the United States each winter – and that’s with double-paned insulating windows installed on a majority of buildings. The Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) is now working with manufacturers to bring to market a “super window” that is at least twice as insulating as 99 percent of the windows for sale today and will be ready to achieve mass-market status.

Helping Arizona Beat the Heat

April 09, 2018

Scientists said they were experimenting with using white paint over black asphalt as a way of cutting temperatures in the Phoenix area. Ronnen Levinson of the Energy Technologies Area said it could possibly reduce the heat island effect, a term given to urban areas that are hotter than nearby rural areas.

Energy-Saving ‘Living Lab’ Climate Leadership Award

A “Living Lab” model led by ETA’s Eleanor Lee received a Climate Leadership Award from the Center for Climate and Energy Solutions.

Berkeley Lab Takes Home 2016 R&D 100 Award for Cool Roof Time Machine

September 06, 2017

R&D Magazine's R&D 100 Awards, established 54 years ago, recognize 100 technologies and services introduced in the previous year deemed most significant by an independent panel of judges. This year's winners received the awards at a November 3 event in Washington, D.C.

Retrofits Slash Energy Use in New York Living Lab

July 12, 2017

By using advanced lighting and automated shades, scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) 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.

Not All Cool Pavements Are Created Equal

May 18, 2017

Berkeley Lab finds that the choice of pavement material can significantly impact carbon emissions, creates decision tool for cities to use

Cool pavements can help keep cities cool, right? Yes, but according to new research from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), many reflective pavements have some unexpected drawbacks relative to conventional pavements when considering the entire life cycle of the materials.

Energy-Efficient Windows Save Billions

April 26, 2017

For the past 40 years, Berkeley National Lab has been partnered with the window industry to help save American consumers money in energy costs by pioneering new energy-efficient windows, design tools, and window-rating systems.

The lab worked closely with window manufacturers and the building industry to develop, produce, validate, and deploy energy-saving low-emissivity or "low-E" coatings. Today more than 50% of window sales in the commercial market and 80% of the sales in the... Read More

Innovative Device Reduces Energy Use in Buildings

December 09, 2016

Researchers from the United States and Brazil have developed a new device that can reduce energy losses in buildings by measuring and assessing the energy performance of windows without removing them from their site.

Fluorescent Ruby Red Roofs Stay as Cool as White

September 21, 2016

Elementary school science teaches us that in the sun, dark colors get hot while white stays cool. Now new research from Lawrence Berkeley National Laboratory (Berkeley Lab) has found an exception: Scientists have determined that certain dark pigments can stay just as cool as white by using fluorescence, the re-emission of absorbed light.
