From 1955 to 1973, he worked in the physics group at University of California, Berkeley, where he did some of the key development of bubble chamber physics, particularly the hardware and software for photographing, measuring and analyzing data.
In 1975, he founded the group that became the Center for Building Science at Lawrence Berkeley National Laboratory. At the center he researched the miniaturisation of electronic ballasts in fluorescent lamps leading to the development of compact fluorescent lamps.
The Center developed a broad range of energy efficiency technologies, including electronic ballasts for fluorescent lighting, a key component of compact fluorescent lamps; and low-emissivity windows, a coating for glass that allows light in but blocks heat from either entering (summer) or escaping (winter). Dr. Rosenfeld was personally responsible for developing DOE-2, a computer program for building energy analysis and design that was incorporated in California’s Building Code in 1978. These codes have served as models for the nation, copied by Florida and Massachusetts, and other states are beginning to adopt them as well. DOE-2 is used to calculate codes and guidelines for energy efficient new buildings in China and many other countries.
From 1994 to 1999 he was a Senior Advisor at the United States United States Department of Energy.
In 2008, Rosenfeld announced his desire to see all new California homes be equipped with a radio controlled thermostat that would allow the State to transmit price and reliability signals to the house, allowing customers to change their energy usage with changes in price.
On March 9, 2010, the open-access refereed journal Environmental Research Letters (ERL) published an article in which more than 50 leaders in the field of energy efficiency proposed a new unit to characterize electricity savings – the Rosenfeld (symbol: Rs). One Rosenfeld is equal to 3 billion kilowatt-hours per year, which represents the electrical output of one 500-megawatt coal-fired power plant under a set of standard assumptions. In reference to such a standard coal plant, one rosenfeld of saved electricity also avoids emissions of 3 million metric tons of carbon dioxide per year. From the abstract:
- The growing investment by governments and electric utilities in energy efficiency programs highlights the need for simple tools to help assess and explain the size of the potential resource. One technique that is commonly used in this effort is to characterize electricity savings in terms of avoided power plants, because it is easier for people to visualize a power plant than it is to understand an abstraction such as billions of kilowatt-hours. Unfortunately, there is no standardization around the characteristics of such power plants.
- In this letter we define parameters for a standard avoided power plant that have physical meaning and intuitive plausibility, for use in back-of-the-envelope calculations. For the prototypical plant this article settles on a 500 MW existing coal plant operating at a 70% capacity factor with 7% T&D losses. Displacing such a plant for one year would save 3 billion kWh/year at the meter and reduce emissions by 3 million metric tons of CO2 per year. The proposed name for this metric is the Rosenfeld, in keeping with the tradition among scientists of naming units in honor of the person most responsible for the discovery and widespread adoption of the underlying scientific principle in question—Dr Arthur H Rosenfeld.
In the Spring of 2011, Rosenfeld was awarded the distinguished Global Energy Prize by Russia. This award is in recognition of his forward thinking and innovations in the area of energy efficiency.
Rosenfeld is semi-retired but still actively promoting energy efficiency. He is currently Distinguished Scientist Emeritus at Lawrence Berkeley National Lab and Professor Emeritus of Physics at University of California, Berkeley. He also serves on the Board of the non-profit American Council for an Energy-Efficient Economy.
