Online Tool Fills Gap for Energy Retrofit Projects

A national online energy data management system is transforming how energy retrofit projects implemented by a wide variety of users – including local, state, and federal governments – develop projects and track performance.

‘Super Window’ Could Save $10 Billion Annually in Energy Costs

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. Lawrence Berkeley National Laboratory 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.

Scientists Discover Material Ideal for Smart Photovoltaic Windows

A photovoltaic glass that is also reversibly thermochromic is a green technology researchers have long worked toward, and now, scientists at Lawrence Berkeley National Laboratory have demonstrated a way to make it work.

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.

Berkeley Lab Helps California Get to Zero Net Energy Homes

California has established ambitious goals to reduce energy consumption in buildings, including a policy goal for all new residential buildings to be zero net energy (ZNE) by 2020. Now Berkeley Lab has launched two projects to help the state meet its ZNE building goals.
