An EETD Seminar on July 22, 2013. Speaker: Lance Wallace, EPA (Retired)
Ultrafine particles (UFP) are implicated in morbidity (oxidative stress) and mortality (cardiorespiratory disease). They are so tiny (less than 100 nm in diameter) that they can evade cell defenses and perhaps can bypass the blood-brain barrier. Unlike larger particles (PM2.5, PM10) they are not monitored regularly in outdoor air. This has left a gap in our knowledge of outdoor concentrations and the major outdoor sources.

An EETD Seminar on July 19, 2013
Speaker: Arman Shehabi, Sustainable Energy Systems Group, Lawrence Berkeley National Laboratory
The energy use of data centers is a topic that has received much attention, given that these buildings currently account for 1-2% of global electricity use. Cloud computing holds great potential to reduce data center energy demand moving forward, due to both large reductions in total servers through consolidation and large increases in facility efficiencies compared to traditional local data centers. However, analyzing the net energy implications of shifts to the cloud can be very difficult, because data center services can affect many different components of society’s economic and energy systems. This presentation will summarize a six-month research collaboration with EETD, LBNL’s Computational Research Division, and Northwestern University to begin addressing this net energy analysis challenge.

An EETD Seminar on July 9, 2013, with speaker: Prof. Paul Waddell, Chair of the City and Regional Planning Department at UC Berkeley.
This talk describes the UrbanSim land use model system developed by Paul Waddell with numerous collaborators, and its application to the San Fransisco Bay Area in support of the regional Sustainable Communities Strategies planning process. UrbanSim is a micro-simulation model system that represents the location choices of households and firms within the region, and the choices of real estate developers to construct or redevelop buildings on parcels throughout the region.

An EETD Seminar presentation on June 14, 2013, by Dr. Jonathan Koomey, Steyer-Taylor Center for Energy Policy & Finance, Stanford University
In 2010, more than fifty of Art Rosenfeld's friends and colleagues teamed up to propose a new unit of energy efficiency: the Rosenfeld. Its purpose was to allow quick, intuitive, and physically meaningful comparisons between energy efficiency savings and power plants avoided. The Rosenfeld is a unit of of electrical power, equivalent to that delivered to end-users by a 500 MW coal plant operating at a capacity factor of 70%, or 3 billion kWh per year. Assuming the carbon intensity of an average coal plant, that avoided generation equates to 3 million metric tons of carbon dioxide per year. This talk will describe how this useful heuristic came about, and summarize the benefits and potential pitfalls of using it to characterize energy savings estimates.

A Tech Close-Up news story about automated climate control in commercial locations in response to real-time signals from electric utilities. The goal is to reduce power demand at times of system overload.
Participants in the development of this technology include Pacific Gas and Electric, Lawrence Berkeley National Laboratory, numerous energy consultants, and commercial electricity consumers such as Ikea (featured here).
