$150 billion/yr. in potential US energy savings, enhanced competitiveness, and reduced CO2 emissions depend on swiftly adopting Diagnostic Benchmarking. Expected savings consist mostly of no-cost Operating and Maintenance (“O&M”) improvements in existing buildings. Early energy audits required that O&M be improved before considering retrofits. But audits didn’t effectively identify O&M opportun...

There is a growing need to develop more robust and energy-efficient network architectures to cope with ever increasing traffic and energy demands. The aim is also to achieve energy-efficient adaptive cellular system architecture capable of delivering a high quality of service (QoS) whilst optimising energy consumption. To gain significant energy savings, new dynamic architectures will allow fut...

Energy simulation models are developed with EnergyPlus for two office buildings in a R&D center in Shanghai, China to evaluate the energy cost savings of green building design options compared with the baseline building. As a R&D center of an international IT corporation, there are data centers in the two buildings, which make them different from typical office buildings. The data centers house...

A Ginzburg-Landau–like functional is proposed reproducing the main low-energy features of various possible high-Tc superconducting mechanisms involving energy savings due to interlayer interactions. The functional may be used to relate these savings to experimental quantities. Two examples are given, involving the mean-field specific heat jump at Tc and the superconducting fluctuations above Tc...

The field of low power compilation could be applied to sensor networks to yield significant savings for the sensing, computation, and communications processes in sensor networks. Such savings could come via simple low power savings flags for future compilers used by sensor network developers. In this paper, we instrument the Moteiv Tmote Sky as a representative sensor, and conduct a set of expe...

The state of California has committed the unprecedented sum of $2.2 billion in ratepayer funds to utility-based energy efficiency programs from 2006 through 2008 and finalized in 2007 the determination of its shared-savings incentive mechanism for the 2006-2008 programs and beyond. A rigorous scrutiny of the California energy efficiency programs and the associated incentive mechanism could help...

The anticipated explosive growth of pervasive and mobile computing devices that are typically constrained by energy has brought hardware and software techniques for energy conservation into the spotlight. While there have been several studies and proposals for energy conservation for CPUs and peripherals, energy optimization techniques for selective operating mode control of DRAMs have not been...
